ABSTRACT: A study is made of the relationship between the results of
the separation of mattes (M) by flotation and the Fe contents
thereof and the rate of cooling of the material to be separated.
It is shown that in order to derive high-quality results in the
separation of M under ordinary factory conditions, the Fe con-
tents should be < 176. When Fe contents are > 31o, the separa-
tion criteria are markedly impaired. The question of spparat-
ing ferrous M was successfully sol *ved by changing the ia'te '. at
which it was cooled prior to pulverization. A slowing of the
rate of cooling makes for satisfactory crystallization of the
phase constituents and permits separation thereof in the sub-
Card I/ Z sequent flotation. Thus, the rate of cooling should be

determined in accordance with the Fe. contents of the M. In order to produce
an Ni concentrate with minimum Cu contents, there is no need that all the
material b6~wund until 80% is -40 microns, inasmuch as the Cu content
of the Ni con(~e*ntrate diminishes to a definite level when pulverized until 501o
is -40 microns, but remains constant thereafter, regardless of the finer
grinding. It is recommended that materials be cooled more slowly before
concentration and multi-stage flotation.

ABSTRACT: Recovery of gold from sulphide ores and concentrates
presents in maixy cases considerable difficulties owing
to the extremely small particle size of the metal which
is present in the miaerals (mainly pyrite) in such a
finely dispersed state that it remains unexposed
(i.e. inaccessible to the. cyanide solution) in material
ground to contain 90% of -325 mesh particles. Oxidizing
roasting treatment is often used to overcome this
difficulty but unavoidable losses of gold in dust
formed during roasting and the fact that a thin layer
of low meltingpoint i1xi&s formed sometimes by
certain ore constituents and enveloping the gold
Card 1/5 particles may defeat the purpose of the roasting process,

SOV/149-58-4-14/26

detract from the value of this method. The
hydrometallnrgical process of autoclave oxidation
appears tq be a more promising solution and caustic
soda or ammonia have been recommended. (Ref.1-2) as
suitable leftching reagents, However, these solvents
are of little practical value owing to their high
cost. On the other hand, it has been shown that
sulphides (particularly gyrites) can be completely
oxidised in water at 120 C, and the subject of the
present investigation was to examine the feasibility of
utilising this fact for developing an efficient and
economical method of pre-treating the sulphide
concentrates containing finely dispersed gold. The
gold content of the five different concentrates used in
the experiments varied between 6 and 43 g/ton. (The
complete chemical analysis is given in Table 1.) The
results of determination of the gold content in. various
fractions of the concentrates with the particle size

insigaificant-proportion of arsenic passes into 'the
solution, since practically all As is absorbed by iron
hydroxide for=d as the result of hydrolysis of iron
sulphate. In the experiments carried out by the
present Author, all iron, 95% arsenic and 50% sulphur
were precipitated in the form of basic salts, in which
a small amount of free sulphur liberated during the
oxidation process was present. After removing the
sulphuric acid solution, the precipitate-treated with
a lime solution to remove the last traces of acid and
to extract free sulphur in the form of soluble calcium
sulphido - was subj*cted to the usual cyaniding
treatment, the results of which are given in Table 3.
side by side with those obtained in cyaniding the
roasted concentrates of the same composition. In the
latter case, the maximum recovery of gold was 8?.5%
with the ma5dunim gold content in the tailings equal
10.g/ton. The corresponding figures for the concentrate

These results confirmed the view that in some cases
the gold-bearing sulphide concentrates can be

TITLE: Flotation-Autoclave Method for Treating Nickel-
Electrolysis Anode Slimes
PERIODICAL: Tsvetnyye metally, 1959, Nr 7, pp 36-40 (USSR)
ABSTRACT: The author points out that Soviet and foreign practice for
primary*treatment of nickel-electrolysis anode slimes are
extravagant in,plant size and,reagents. Drawbacks re-
mained in the gravitation-hydrometallurgical method
developed in 1940 by the Leningradskiy gornyy institut
(Leningrad Mining Institute).and applied at a Soviet works.
After research on this a gravitation-autoclave method was
r.ecommended by the author (Ref 1) (Figs 1 and 2 show sul-'
phide oridation as a function of temperature and oxygen
consumption as a function of time, respectively). It was
later decided to use flotation instead of gravity concen-
trationl work abroad (Ref 2) having proved promising. In
contrast to this work (Ref 2) the author dealt with

Slimes
and some nickel ferrite. Preliminary experiments showed
that in acid solution flotation of sulphides, selenides,
tellurides and noble metals is very active; part of the
copper and nickel went into solution while the nickel
ferrite and nickelous oxide were mechanically entrained in
the concentrate. Optimum H2SO4 concentration in the pulp
was found to be 20%, though 3-5% and 250 g/ton of reagent
gives satisfactory results. Alcoholic IM-66 was used as
frothing agent. With re-purification of the flotation
concentrate its recovery was about 60%. To improve its
quality wet electromagnetic separation was used, the pro-
duct (mainly sulphides of nickel and of copper) being
subjected to autoclave treatment. A flowsheet (Fig 3),
based on these results, used to treat several portions of
slime; the combined products showed a high concentration
(Pt * Pd;;p 56%) and recovery of platinoids in the final
concentrate (Table), whose yield is about 3%. Further
improvement is obtained by roasting at 800 - 9000C. The

under sulphiding conditions to give a platinoid-enriched
product for retreating with the feed slime: overall
platinoid recovery can then rise to 99%. Losses of rare
platinoids in autoclave solutions were small, but the
author mentions the possibility of precipitation from
sulphate solution. The flowsheet provides for recovery
of selenium and, in some cases, tellurium, a separate
method for their recovery, developed at the Leningrad
Mining Institute by T.N. Greyver (Ref 3), is also
available. The author recommends the large-scale testing
of this flowsheet. There are 3 figures, 1 table and

ABSTRACT: Amalgamation of Permalloy, Kovar (18% Co, 29% M, 53% Fe), alloy E1996:
(2% Be, 93% Ni), platinum and "Armco" iron was studied by measuring wettability by
mercury under various conditions calculated to prevont formation of oxide films. These
included hydrogen reduction of the test plates and wetting under an acid layer following
-electrolytic reduction of oxide films. Surface preparation and experimental techniques
are described. Other experiments involved effects of temperature, environment,
hydrogen pressure and the Hg-Pd contact period on solubility of Pd coatings in mercury,
as Well as the wetting of these metal and alloy surfaces by zinc, ammonium and sodium
am The results Indicate that amalgamation of Iron-nidwl alloys cannot be effected

ABSTRACT: A discussion is presented of the two fundamental operations
in a flowsheet developed by the Mekhanobr Institute for a soda
autoclave process of treating VI-ore concentrates: Autoclave
leaching (AL) and separation of the W and Mo. The conditions
for maximum extraction of the metal in solution and the methods
used to reduce Na?C03 consumption in AL and of reacting
Na2C03 with CaW04 are examined, as is the efficiency of the
introduction of balls into the pulp in AL and examples of AL of
products' high in W and Mo. The Mekhanobr investigations have
established, and industrial practice has confirmed, the possibil-

ABSrRACT Since i948 the ".Russkiy dizell" works has been making en-
-gines of the families A and AP 30/50-with outputs of 400, 600
and 800 h.p.'at 300 r.p.a. which hava been widely used. The
most extensively used are models 6 AF 30150 and 8 A?30/50 which
are used as the main engines in ships vith direct drive-of the
screw. Engine AP-30/50 is two-stroke, trunk type, compressorless
reversing engine,working on solar oil or diesel fuel. The prin-
cipal data of engines-A and AP 30/50 are given in Table 1.
Engines A and"Af 30/50 are simpler and convenient in operation and
repair and cheap to.produce. They are very reliable but they
have a number of defects suc4 as the appearance of cracks in the
pistons of engines made befote 1951, contamination of the lubricat-
ing oil system by fuel and high wear of the universal joints of
the lubricator drive and various other defects. Therefore, the
Russkiy dizell works, in 1955, worked out a project of modern- .1
isation of engine 8 AVL30/50-2, a general view of which is given
1/3 in. Fig.l. A most important item in the modernisation is the
introduction-of oil cooling for the main pistons. This makes the

Modernisation of (diesel) engine 8 Ai~ 30150. (Cont.) 3a4/7/3.e/i4
engine more reliable and^affords the posiibility of'increasing the
output of the engine by increasing the speed and using super-
charging. The construction of pistons with supply of cooling oil
through the. crankshaft And- connecting rod is illustrated in Fig. 2.
The use of oil cooling made it possible to reduce the temperature
of the piston head from 600 - 635 C to 400 C. The piston rings
and particularly the oil control rings were altered and are now
of longer life. With the introduction of piston cooling a greater
quantity of oil is required and the output of the oil pump, filter
and cooler have been increased. The design of the super-charger
pump, illustrated in Fig.3,'has been considerably altered. The
driving mechanism of this pump has also been simplified and im-
proved. The compressor cylinder, which is little used, has been
removed from the engine, which simplifies servicing and improves
reliability. The governor has been improved. A new main starting
valve has been.designed and is illustrated in Fig.4. It is more
reliable than the previous design. in order to cut down the time
required to approve the modernised engine as a whole, most of the
parts were tried out for considerable periods in standard engines.
2/3 The complete modernised engine 8 AP-30/50-2 has been tested for
3000 hours including an 800 hour acceptance test and this

Modernisation of (diesel) engine 8AP30/50--(Cont-)
confirmed the reliable oberation of 'the irarious mo&riised parts.
The main parameters of the engine, which are tabulated in Table 2,
were of satisfactory stability. The operating economy of the
engine has been improved. The fuel consumption has been reduced
by 4 grams per horse-power hour and is on an average 178 grams
per horse power hour, the oil consumption has also beEnreduced.
The works has now turned over to regular production of the modern-
ised engine. By increasing the speed of the modernised engine to
375 r. in. it can develop 1000 h.p. With the use of super-
char using the energy of the exhaust gases and relatively
,Silt
pressures of blowing air, the engine power can be in-
creased to 12~O - 1300 h.p. The factory is carrying out work on
the application of a closed cooling system for the engine using
fresh water. The closed cooling system is particularly effective
on the modernised engine which is capable of using cooling water
with an outlet temperature of 70 - 80 C. The fuel consumption is
3/3 then reduced bY 3 - 4 grams per horse power hour. 114-7-29/3-4

at not more than 600 imp/min while the specimens revolved at 60
rpm. The reflection intensity from the (111) planes was measured.
The ageing was performed at 6000Y 7000 and 8000C for periods of
0.25 to 50 hours. Along with the intensity changes, changes in the
hardness were also measured. The ageing of all 4 alloys resulted in
strength increase. The changes of both the intensity and hardness
depend upon the ageing temperaturet but are not parallel. Thus,
the intensity of reflection does not always increase in the initial
stages of ageing as..does the hardnesso At relatively low ageing
temperatures the strengthening is not accompanied by appreciable
changes in t* mosaic structure which contradicts the data of Pivo-

loy was similar to that of the Ni-Al alloyp but the change in the
substructure was less pronounced. The Ni-Cr-Ti alloy showed similar
ageing, to that of Ni-Ti, the process being slower. It is concluded
that the strengthening during ageing cannot be ascribed to the chan-

TEXT. The purpose of this work is to investigated the kinetics of oxidation and the phase composition of the
oxide layers formed on the surfaces of 3K-813, and 311-835 stools and of 3K-559A and 3K-652 alloys when
they are heated in the air from I to 100 hours at 900*, 1000*, 1100* and 1200*C. The high corrosion resis-
tance of these alloys is due to the formation of oxide layers of the spinel type on their surface. The EI-813
and EI-835 steels have a high heat-resistance up to 1000-1050*C due to their high chromium content. The
authors refrain from explaining all the experimental data obtained as they consider their investigation to be
unfinished. In the discussion, Prokoshkin D. A. pointed out the inconsistency of the data on the position of
the Cr,203 layer, There is I figure.

TEM A device developed by R. Castaign (Rech. A6ronaut. 23, 41 (1951);
ONERA, 55, 10952)) was used for the microspectroscopic analysis.
Castaign's microprobe was used to study the dendritic liquation of sili-
con in 55C2 (5532) spring iron (3-5 tons) containing 1.66~~ silicon. The
liquation degree is very high in the axial- part where the dendrites are
especially large; the ratio between maximum concentration in the inter-
axial region and minimum content in the axes is 2.0. Vihen the steel is
rolled, regions of low and high silicon concentrations appear in the form
of thin bande which# after homogenized annealing for 12 hrs at 1200 0 C,
at some places leave a broadq blurred band. Data obtained by X-ray
spectrum analysis on the distribution of nickel in the digfusion layer

heated to 1100 C showed redistribution to occur between the cz-phase and
T--phase of 24.4 and 20.7%, Cr and 4.47 and 6.85% Ni, respectively. The
change in composition of the solid solution and phases separating on the
ageing of alloys were investigated. -:)A 726 (E1726) alloys were studied in
the initial state and after 20.000-hr ageing at 7000C. In the initial
state, only an excess phase (phase I) can be seen on the screen, whereas
after ag-eing small and large bMsh segregations (phaso II) appear. In-
solid solutions, age-ing causes a cLecrease in tungsten and niabium contents
owing to the precipitation of an intermetallic phase with a high content
of these elements (phase II) An W-type lattice was determined by A-rqy

analysis. Phase I containing 71~u Nb appears to be a niobium nitride or
niobium carbonitride. Carbide contains no tungsten and does not change
its composition even after long-time ageing; other carbide-forming elements
are probably not contained in niobium carbide. In the Fe-Cr-Ni alloy type
