ABSTRACT: A presentation, o! results of studies of oxidation rates of
molybdenite and of its interaction with M003, as well aJ of the
interaction Of M003 with CuO, CaO, FeO, and ZnO -avd of the
solubility in ammonia of molybdates formed in the proc..:,s. The
process of FluoSolids roasting was studied in a laboratory fur-
nace with a cross section of 400x150 mm. The following was
established: optimal tempIrature: 5850-5950C; specific output
of the hearth: 1.5-1.6 t/m ; extent of dust removal: 38-42 per-
cent; it was also established that the roasting process may be
carried out without fuel by means of utilizing the heat from the
reactions. Cbernical composition and results of leaching of
Card 1/2 cinder (which results from the FluoSolids roasting process)

A Study of FluoSolids Roasting of Molybdenite Concentrates
are shown, together with analogous information for an industrial roasting
process carried out in a rotary furnace. Extraction of Mo from cinder, pro-
duced in the course of aprocess of FluoSclids roasting, is 921.0-93.5 percent
as compared to the 79.0-79.5 percent Lchieved in the industrial process, The
amounts of tailings from the.two pr. cesses constitute 20-22 percent and 36-
38 percent, respectively.

Title :Vapor Pressure of Molybdenum Trioxide at High Temperatures
Orig ?ub :Zh. neorgan. khimii, 1956, 1, No 4, 632-637
Abstract :The vapor pressure of molybdenum trioxide was determined at temperatures
above the melting point from the baling temperatures at constant
pressure, The following equation was derived for the vapor pressure of
moo : log P~~-7685/T _~_8.26. The latent heat of boiling of Moo 3 is
35-1 *-cal. Comparison of the vapor pressure determined by the Jet method
with the true vapor pressure confirm the assumption that the molybdenum
trioxide molecules become polymerized in the gas phase. The probable
compwiition of the gas molecules at temperatures of 950 lo-boo cor-
responds to M0309'

Title Study of the Reaction of,Oxidation of Holybdenite
Orig Pub: Zh. neorgan. khImli, 1956, 1, No 10, 2245-2256
Abstract: It is shown that at Wo, 5oo and 6ooO molybdenite (I) is oxidized
by oxygen of the air, directly to MoO_? (II). Intermediate inter-
layer of MoOa.,which is observed only at 60001 is formed as a re-
sult of secondary interaction between I and II. Rate and regulari-
ties of the oxidatica of I, at different temperatures, depend on
structure of oxidic envelope. At 6000 this envelope is friable,
velocity of the process is determined by velocity of the chemical
reaction, extent of oxidation depends linearly upon duration, velo-
city constant K - 0.0085 =a/minute. At 5000, as oxidation proceeds,
there is observed a transition from kinetic conditions, o-er inter-
miate, to diffusion conditions, which &-re attained with a thickness

TITLE: The Precipitation of Tungsten in the Determination of this

ABSTRACT: The methods for separating out tungsten from different
molybdenum products are not yet sufficiently worked out.
Usually a colorimetric method is used in which the penta-
valent tungsten forms a yellow complex with a thiacyanogen
salt. R~en the molybdenum concentration is preponderant
a separation must first be carried out. This-is accomplished by
precipitating the tungst en with iron oxide, according to a
report from the Institut tverdykh splavov MTsM S31SR (Institute
for Hard Alloys MTsM USSR). The precipitated tungstea is then
removedq dissolved in hydrochloric acid, and determined colori-
metrically after the iron is first precipitated with lye.
The completeness of the tungsten precipitation was investigated
Card 1/2 using the radioactive isotope tungsten-185 as an indicator.

-The Precipitation of Tungsten in the Determination of SOV/32-24-8-9/43
this,Element in Molybdenum Products
These investigations showed that 70-79% of the tungsten
is precipitated, so this method is not suitable for an
eyact determination of -.Lngsten in molybdenum products.

ABSTRACT: Until 1949.there was no production of rare metals in
China-
this also refers to tungsten, the reserve%3 of which
are very considerable; China's export of tungsten.concen-
trates constituted about one half of world's output.
The Soviet Union helped China develop its production by
sending specialists and by permitting Chinese specialists
to study in the Soviet Union. Ohina now produces gallium..
indium, thallium, selenium, and tellur ium, which are
prepared from byproducts, of nonfervous metallurgy.
Conventional methods of their preparation are described
by the author but no names'of plants or production
figures are given. Ferrous alloys, ferromolybdenum,
ferrotungsten, and carbide's, and metallic tungsten and
Card 1/2 molybdenum are now produced in China, and there is no

TEXT: The method of preparing niobium and titanium chlorides from
TIC and NbC, which may be obtained from oxides or directly from Ti and Nb
concentrates, is of considerable interest. Infomation ip- given on results
of investigations into kinetics of chlorinating pure Ti and Nb carbides.
Carbide powders were used as initial material, obtained by the reduction of
TiO and NbO, oxides with lamp black in a coal.-tubular funiaoe in hydrogen
atmosphere fit 1,9000 - 2,00000 and 1,,7000 - 1,80DOCreepiotively. The
chemical composition of the carbides is given in Table 1. The experiments
were performed on compaot~cylindrical 'specimens contained in a tube; chlorine
flrjw was passed through -the tube at a certain speed and temperature; the loss
In weight of the specimen was recorded as well as the amount. of chloride de-

Kinetics of the Chlorination of Titanium and Niobium Carbides
in Pigure 1. The weight loss of the specimens was the basic and most accurate
indicator of the chlorination rate. -The experimental results were expresdid
in the weight rate Wcm:2.min) or linear i-ate . (mmlm.Ln) - characterizing the JX-
tension of the process into the depth of the specimom. Computational data were
checked by direct measurements with the aid of a binocular microscope (x 28).
Table 2 shows that the computational and measured viLLues are in a satisfactory
agreement. The following conclusions are drawn; Ilia chlorination process waz
accompanied by the development of an external graphite layer whose effect an
the rate of the process was not not-ced at 4000C; et 6000 and 8000C a certain
diffusional inhibition of the reaction was observedl cifLorination acquired
the characteristic of an intermediate process between the kinetic and diffusio:z
processes, the first one being prevalent. It was established that the compact
Nb carbide was chlorinated slower at'8000 than at 6D30C. This Is apparently
due to a higher adhesion strength of the graphite 1Nrer to the Nb caLbide. The
chlorination rate of Ti carbide increased rapidly at higher temperatures. The
revealed dependence of the chlorination depth on the duration of the process
was used to calculateLthe optimum time of chlorinatit,.)n of Ti and Nb carbide

TEXT: The processing of Ti-Nb raw material by the method of carbidization
and chlorination was conducted on a laboratory and enlarged scale. The method
consists in heating a mixture of the concentrate with coal in an electric furnace,
at 1,800 - 1,9000C. The complex raw material elements are then transformed into i "_'
carbides and divided into the following tWo groups according to their properties;:,
1) TiC, NbC, TaC; SiC - strong refractory compounds, and 2) carbides of rare
earth elements Ca, Na, Al and Fe, dissolving in diluted acids. Processing of a
carbidization product with 10% HC1 makes it possible to separate all soluble

The lubricating properties ol' natural MoS 2 (molybdenite),
supplied by the Sobin Refining Plant, and of synthetic.
MoS were compared by testing both materials in. oil
sus~elnsion in TsNIIMASH and VIAM friction testing
machines. The lubricating properties of both additives
were practically equal. Synthetic MoS 2 was obtained:
(1) on fusing Moo 3 with sulfur and sodium carbonate;
optimum conditions: sulfur in 15% excess, temperature
7000 C,Itime of reaction 1 hr', (2) on fusing CaMo04

TEXT: The authors present the results of their study of: (a) the
distribution of Re in the products obtained from roasting Kadzhara
molybdenite concentrates.in a boiling-layer furnace, (b) the re-
covery of Re from waste gases of a boiling-layer furnace by means

of a bubbling unit, and (c) the behavior of Re during the calcining
of Koundrad concentrates in the same type of furnace and the ex-
traction of Re with a similar bubbling unit. A tentative scheme is
also suggested for reprocessing bubbler pulp to obtain metallic Re.
It is noted that recent research at the Institut tevetnykh metallov
im. M. I. Kalinina (Institute of Non-Ferrous Metals im. M. L Ka-
linin) has indicated the advantages of the boiling-layer furnace
as compared with tubular, muffle, and reverberatory types. Diagramsll__'~
illustrate the dust-collection system of the boiling-layer furnace,---
the bubbling unit designed by the Gintsvetmet (State Institute of
Non-Ferrous MetallurgyT"for the recovery of furnace gases, and the
laboratory model of the boiling-layer furnace employed by the au-
thors in their tests. The Re distribution in the roasting products
of Kadzhara concentrates, the Re content of bubbler pulp, and the
Re balance for both the bubbler and the furnace as a whole are gi-,
ven in tables. Conclusions: 1) The roasting of Kadzhara concent-
rates in a boiling-layer furnace ensures the fullest sublimation
of Re; 92 - 96% of the Re is sublimated in this type of furnace
Card 2/3

S/697/61/000/000/004/018
Study of the behavior ... D228/D303
as compared with only 50 -_675 in muffle,and rotary tubular furna-
- ces. 2) The existing dust-collection system of the boiling-layer
furnace does not guarantee a satisfactory degree of Re extraction,
since the loss of metal in waste gases amounts to about 80%. The
lowering of the temperature of the Cottrell filter to 55 - 800 do6s
not reduce this.loss on account of the condensation of H 2so 4* 3)
Much better results can be obtained with the bubbling Unit, and the
bubbler's efficiency with respect to Re Is stated to equal 89 - 96%.
75 - 92% of the metal in the' bubbler pulp is in solution, and the
concentration of dissolved,Re rises as the duration of the bubbling
lengthens. It is recommended that the pulp be removed from the bubb---~
ler when the Re concn. and acidity of the solution is 0.15 - 0.3 and
30 - 50 g/1 respectively. 4) The high degree of Re sublimation (92
93,2%) from the ash of Koundrad concentrate shows that the same
technique can also be applied to this materiali there is no diffe-,
rence in the behavior of Re during the roasting of both cancentra.-
tes and the processing of their gaseous products in the bubbling
unit. There are 3 figures and 4 tables. /-Abstracter's note: P,,48

TEM Information Is given on the autoclave method of rhenium precipita-
tion from potassium perrhenate solutions at elevated temperatures and high hydro-
gen pressure. The authors studied the eftect of the medium (initial acidity of
the solution), partial hydrogen pressure, temperature, time and potassium per-
rhenate concentration, on the rate and degree of rhenium deposition-and on the
composition of the deposits and the metallic powder-obtained. The investigation
was made with the participation of graduate A, Peredereyev, on a stainless steel
1-~. .r autoolave with a magnetic mixer designed by Visbnevskiy. The siction
of the mixer that is located in the reaction zone and the Impeller, are made of
titanium. The autoolave was heated by a dismountable electric fu=.ace whose
temperature was regulated by an electronic potentiometer 91A-12 (EPD-12). The

batch of potassium perrhenate was placed into a quartz glass container, filled.
with 200 ml distilled water and the rated amount of sulfuric acid. After heating
the.autoclave to a given. -temperature, the mixer was.switched on and the hydrogen
was added until the required partial pressure was attained. The pressure was
maintained constant. The results of each experiment were evaluated from the
rhenium content in the solution and in the wasted and dried precipitate, and
from changes in pH of the solution. Rhenium content In the solutions was deter-
mined by the photocalorimetrical method and in the precipitates by the weight
method. The precipitates were reduced with hydrogen to metal and the rhenium
metal was analyzed as to its content of potassium sodium and calcium. It was
found that 98 - 99% Re were precipitated into a deposit which contained rhenium
particles and lower Re oxides under the following conditions: potassium per-
rhenate ooncentration,25 - 150 g/l; hydrogen pressure 10-60 atm.; temperature
2000C. It is shown that under optimum conditions of autoolave reduction (KReoj~ -

admixtures of potassium, sodium and calcium. Theset values which are permissible
in respect to the sintering properties of powder-pressed rhenium, correspond to
the purity of rhenium obtained from ammonium perrhenate by the conventioral

TEXT: The crystal structure of powdered MOS2 prepared by five-

Sample onewas formed by the tnteraction of mol,,--denum trioxide

P-MOS2. Fig.3 is a comparison of the results of X-ray studies for
the three types of structure (a - a-MOS2,- 6 - P-MOS2, B and '2
new structural type). Since the interplanar distance is the same
in going from one form to another, it can be assumed that the
layered lattice and the disposition of the sulphur atoms around
the molybdenum is retained. It is.proposed that the new form is
hexagonal with c greater than in the lattice of P-MoS2.
Changes can be seen in the new structure depending on its method of
preparation. This is explained by statistical interchanging of
hexagonal and rhombohedral packing. The lubricating properties of
the artificial MOS2 are not different from those of natural MoS2.

MUODICALI Zhurnal prikladnoy khimii, v. 34, no. 3, 1961, 679 - 682
TEVt A preparative purification method for molybdenum trioxide from tungsttn
and other impurities is described- The method is based on distillation of molyb-
denum oxychloride by heating a mixture of molybdenum trioxide and sodium chlorlds.
Thus the turiggten content can be decreas-'d from an Initial content of 0,01 to 1%
W down to 10-1 - 10-3% W. The present method was already published by A. N. Zelllc-
man [Soviet patent no. 1131145 ~1957)1 and develope4 as a result of prior iuvesti-
gations (Ref. 1: ZhOlVa, 24, 1916 (1954)]. Previous experiments demonstrated the
reaction of MoO5 with NaCl at 5000 - 70DoC resulting in formation of sodium molyb-
date and dioxychloride, The latter evaporates at this temperature. On the other
hand it was'Observed that at 5000 - 6500C tungsten trioxide does not react
sodium chloride forming volatile compounds. Tests for the present method m:e,' , car-
ried out with MoO3 + W03 mixtures varying +Aie ratio of W/(Mo + W) from 1 to 2~%.

The mixtures were obtained by mixing an ammonium molybdate solution with ammonium
tungstate solution with subsequent evaporation of tho liquid and calcination
(5500 - 60000 of the residue. The latter was then thoroughly mixed with finely
ground s6diiar, chloride, placed in a horizontal tubular oven and heated by passing
air (about 10 Vhr). Molybdenum oxychloride sublimated, was dissolved and molybde-
num and tungsten were determined, The latter was first determined colorimetrically
by the method of the Vsesoyuznyy institut tverdykh splavov (All-Union Institu:~e of
Solid Alloys), but since this method was insufficient in further fxpcriments a
spectral-inethodo developed in the MDU.(Moscow 6tate University) by N. 1. Tarasevich
et al. [Ref. 4: zL, 8 (19~91] was applied. The obtained results (Table 1) demon-
strate that the sublimates contain a maximum of about 0,001% W/(Mo + W), azO irde-

TITLE: Separation of cerium from other rare-earth elements using the method
of oxidation with oxygen under pressure

TEXT The authors studied the possibility of accelerating oxidation of
Qe3t in aqueous pulp of rare earth element hydroxides by pressure as developed
In Oranienbaum (Germany). The acceleration can be aclAewd by the use of oxygen,
and by raising the temperature and pressure. Experimental investigations were
made on a 1-liter-autoclave with a Vishnevskly electromagnetic mixer at 2,600
rpm. The solid-liquid ratio in the pulp was 1 : 5. The necessary alkalinity
of the pulp was obtained by the addition of a 40% NaOH solution. To produce a
neutral or weakly acid medium the pulp was neutralized with nitric.acid. The pH
value was determined with a J111-5 (LP-5) potentiometer with a glass electrode.
The effect of the oxidation medium, the temperature and the method of preparing
the hydroxide, on cerium oxidation in the pulp was investigated. Studying

the effect of alkalinity, partial o3qygen pressure and temperature on the rate
and completeness of cerium oxidation, the following optimum conditions were
found- pH = 10, oxygen pressure 5 - 10 atm; temperature 1300C. Under theje
conditions full Ce oxidation is cbtained within 30 minutes. The rate of ile +
oxidation depends on the method of preparing the hydr3xides; oxidation in a
mixture of hydroxides precipitated from chloride solutions with ammonia, pro-
ceeds incompletely. In a mixture .-f.hydroxides, obtained by the decomposition
of b1sulfates, or precipitated wiLn caustic soda, cerium oxidation proceeds ra- .01
pidly. Cerium concentrates with up to 95% CeOp content can be obtained. This
article was recommended by the Kafedra metallurgii redkikh metallov (Department
of Metallurgy of Rare Metals) at -the Krasnoyarksiy institut tsvetnykh metallov

TEXT: The authors investigated the possibility of
accelerating the process by the use of oxygen at increased
tetnper~aturez (25-200 *C) and partial pressuires (3-15 atin), using
in the ~xpcriments a mixture of alkali earth hydroxides obtained
from a malt.of chlorides containing, ~,):' 29.55 rare earth elements
(of which 509.0 was Ce0q); .7.61 CaOi 2.37 SrO; 0. 51 MnO;
0.23 Fe2U3; 0,43 Th02. After solution of the chlorides in a
2~'o hydrochloric acid and purification from thorium and partially
from iron and manganese, the rare earth elements were precipitated
as acid sulphates and the latter decomposed with sodium hydroxide
(in some cases directly precipitated with sodium hydroxide or with

hydroxides - of rare earth, ale,inents in an aqueoUs pulp With oxygen
under pressure, optimum condiiio_n~s~ 10, oxygen pressure
10 atm, temperature 130 C. Under these conditions complete
oxidation of cerium is achieved in 30 minutes. The velocity of.
oxidation of Cc3+ depends on the method of preparation of the
hydroxides. oxidation in the mixture of hydroxides, precipitated
from a solution of chlorides with ammonia, is incomplete; Ce
oxidises rapidly in a mixture of hydroxides produced by decom-
position of acid sulphates, or precipitated with sodium hydroxide.'
After the oxidation, cerium was separated from other rare earth
elements by treatment with a 105~ nitric acid. Concentrates
containing up to 95ulo' of CeOO can be obtained.
