ABSTRACT: The corrosional and electrochemical behavior of the Mn
electrode in an Mn electrolyte (mixture of MnS04 and
(NH4)ZS04) was studied. It is established that the rate of cor-
rosion (according to the evolution of HZ) increases by jumps
according to the increase in (NH4)ZS04 content with the Mn con-
tent remaining constant. The rate of corrosion of Mn and its
electrode potential varied considerably with time, while this
change increased with an increase in the concentration of
(NH4)ZS04';."Mean-.vhile, the potential showed a considerable
tendency towards displacement in the negative sense. The

ABSTRACT: The corrosion and the electrochemical behavior of short-
circuited couples consisting of Mn and metallic admixtures
(Cu, Ni, Co) depositing on the surface of Mn in a manganese
electrolyte (MnS04, (N'V2SO4) was studied, In contact with
these metals Mn corrodes with a noticeably positive difference
effect, but the intensity of the work of all the couples studied
is about equal. The work of the couples proceeds under cathode
control. The data obtained provide no possibility to attribute
the increased reverse solubility of Mn during its electrolysis
in the presence of Cu, Ni, and Co to the work of the galvanic

ABSTRACT: A study is made of the effect of Ni, Co, and Cu ion impuri-
ties upon Mn electrolysis. When Mn is subjected to electrolysis
in the presence of impurities, an increase in the intensity..of
the effect of the impurities is observed according to the sequence

Card I/Z few percent Mn precipitate at the cathode. These alloys may

be obtained by electrolysis, with a current efficiency of > 400,16. 2. Ions of
Fe34, have a considerably smaller influence upon electrolysis than do ions
of Fc2~ . When the Fc3+ contents of the E rise fron-1 0.01 to 1.0 g/liter, the
Mn current efficiency declines insignificantly (fron-1 64 to 59%). 3. Addition
of up to I g Al/liter has an insignificant effect in decreasing Mn current ef-
ficiency, but at 3 g Al/liter, the entire E is filled with a gelatinous precipi-
tate of AI(OH)3, the current efficiency drops 107o, and a small amount of Al
is found in the cathodic Mn. 4. As and Sb have a harmful effect upon N4n
electrolysis. 0.001-0.05 g As or more per liter results in a sharp decline ill
currernt efficiency and impairs the quality of the cathodic Mn. The presence
of large amounts of As causes cessation of deposition of metallic Mn, and a
black tarnish appears on the cathode. Before the solutions arrive for elec-
trolysis it is necessary to purify them of Sb and As by cementation of the Mn..
5. Na does not have a harmful effect upon cathodic deposition of hin.

TITLE: The Influence of Phosphorus on the Electrolytical Recovery of
Manganese (Vliyaniye fosfora na protsess polucheniya elektro-

PERIODICAL: V sb.: Elektrokhimiya margantsa, Tbilisi, AN GruzSSR,

ABSTRACT: The influence of P on the process of cathode deposition of
Mn from sulfate solutions was investigated. P was introduced
into the electrolyte in the form of (NH4)ZHP04; it was estab-
lished that as the P content varied frorzi 0.01 to 5 g/liter the
current efficiency diminished from 60 to 181o. Upon removal
of the Mn phosphate deposit the electrolytic precipitation of Mn
proceeds with a normal current efficiency. Tests were per-
formed relative to the leaching of high-phosphorus ferroman-
ganese by HZS04, and the distribution of the P between the pre-
cipitate and the solution was established, also the degree of
fugacity of the P relative to the acid concentration. The follow-
Card 1/2 ing was established from tests comprising the oxidation of Fe

in the solutions obtained after leaching: a) At a pH of 1-2 the Fe o.Xidizes
fully and upon further leaching up to a pH of 5 it precipitates in the form of
Fe (OH)3 which is readily separated by filtration; b) the oxidizing activity
of MnO2 diminishes significantly with increasing pH. At an electrolyte pH
of 3-4 the solutions contain Fe(OH)2 which is not retained by the filter.

of Mn and NH4 in accordance with the concentration of Mn in
the electrolyte (E), the temperature, and the pH of the E. The
following is established: 1. From a standard solution contain-
ing 150-180 g (NH4)2SO4 and 20-25 g Mn/liter having a pH of cd
7.0-7.2 and a temperature of -200C it is possible to separate
Mn only .vhen cd > I amp/dm?-. Maximum current efficiency
with these solutic~n_s was observed when cd was 2 amps/dmZ.
2. A particularly pronounced drop in current efficiency is ob-
served with an increase to cd> 5 amps/dmZ. 3. The higher

of 1.7 it is possible to recover Mn when cd is 6-10 amps/drnz, 5. At high
Mn in the E, an increase in cd has a lower influence upon the indices of the
process of electrolysis. 6. The S content in the cathodic Mn increases with
increasing cd.

ABSTRACT: A study is made of anodic polarization (AP) of Mn in solu-
tions of KOH, NaOH, and Na2CO3 of various concentrations, by
plotting polarization curves by the compensation method, and
also by rneans of the Vagramyan recording apparatus. The use
of the Vagramyan method and apparatus made it possible to dis-
cover segments on curves for concentrated KOH and NaOH sol-
utions where 02 liberation proceeds without formation of Mn-4,
and also made it possible significantly to dirninish the effect of
oxidation of the surface on the process of AP and of determin-
ing the shape of the curves in the first stages of polarization
and oxidation of the anode. This did not prove possible by the
method of compensation. Bibliography: 9 references, 1.

of average purity does not provide a reducing environment, it
is not possible to precipitate metallic Mn therefrom by electro-
lysis, and if the content of reductants is higher than the opti-
rnum, they exercise a negative effect; 2) as the quantity of sul-

in the E or presence therein of negligible amounts of oxidizer result in ex-
foliation of the cathode deposit; 4) the yellow anolytes formed when the E is
of high acidity contains an oxidizer that may cause peeling of the cathodic
metal; -11) addition of certain colloids and surface-active substances facili-
tates precipitation of Mn at the cathode from contaminated solutions; the
effect of the addition of colloids upon E carefully cleansed of impurities upon
the process of cathodic precipitation of Mn is 'insignificant; 6) addition of
soaproot to the F has a positivo effect in quantities of 0.001-0.1 g/liter.
When larger amounts are 'added, the current efficiency diminishes. Soap-
root reduces losses of E from the bath and facilitates removal of Mn de-
posits from the cathodes.

gated in an effort to replace them with Al. The degree of ex-
traction of Sb increases as the quantity of metallic Al intro-
duced into the reacting mixture is increased; it reaches a max-
imurn when the amount of Al is twice as great as the stoichio-
metric value. Introducing ar, excess of NaOH into the initial

ABSTRACT The carbonizat3on process was carried out in a 300-c( re-
action vessel ()8% of C02 from a tank were introduced through
a constant-pressure vessel. The quantity of gas being supplied
to the reactor vessel was determined by means of a transparent
tube-type flow gage. The carbonization of the solution showed
that the reaction of Sb sulfo salt with COZ produces an Sb sul-
fide precipitate and that the ( ompound NaHC03 forms in the
solution ac(on-ipanied bV the liberation of H_7S. If the tempera-
t LAre is raised to 1000C the carbonization process terminates in
the formation of Na2C03. The. amount of COZ needed for com-
plete carbonization of the solution is a dire(t function of the
concentration of Sb in the solution. Best results were obtained

ABSTRACT: A description is offered of experiments in cathodic precipi-
tation of Fe from FeS04 solution with soluble (steel, iron) and
insoluble (Pb) anode .s. The experiments studied the influence
of current density, -the strengths of the FeS04 and Fe2(S04)3,
the acidity of the electrolyte, and the duration of the experi-
ment on the process of electrolysis, the quality of the precipi-
tate, and the unit consumption of electric power. It is estab-
lished that the current efficiency for Fe from boiling solution
containing 200 g FeS04/liter, is 93-97%; the power consump-
tion per kg cathode -deposited metal is 1.5-2 kwh with soluble

ABSTRACT: In the Iresent paper the action of iron on the structure and
properties of alloys obtained from manganese and copper was in-
vestigated. The alloys in the manganese corner of the ternary
system manganese-copper-iron were investigated vrithin the
concentration range of 50-1W-0' Lin. The initial materials used
for the production of these alloys had a purity of 99,6~o. The
investigations of the alloys dealt with the microstructure,
e,lectric n.~sistance and dilatometric analysis. In the alloys
containing 60-90~c manganese and the same quantities of copper
and 'iron, the microstructure corresponds_ to the eutectoid type.
This structure was probably caused by the decorl'oosi'ion of the
P-manganese phase. A dendritic 3tructure occurs in alloys con-
taining 50-60~'L' manganese, after th-eir Gradual cooling. The in-

the ternary system show that an addition of iron does not
stabilize the r-solid solution. ;ill alloys containing 50-100~-
manganese are two-phase mixtures of r+a Yn. The electric re-
sistance was measured by means of the potentiometer of the
P1017 -1 type. The results of the determinations of the electric
resistance are presented in table 3. The transformation a-'110
manganese in the binary alloy Mn-Cu could not be found by dilato-
metric investigations. However, -- transformation of that kind
can easily be observed by a dilatometric investit;ation of the
binary alloy Pe-11n. It follows from these investigations that
an addition of iron to manganese alloys does not exert any in-
fluence upon the stabilization of the ~-solid solution, but
causes the intense decomposition of this phase on a decrease in
temperature under the formation of the a-manganese phase, due
to which the alloys become cracky. There are 5 figures, 3 tables,
and 6 references. 3 of which are Soviet.

ABSTRACT: The system manganese-copper-cobalt and above all ternary systems
enriched with manganese were investigated. Purest electrolytical
manganesep copper, and cobalt with a purity of 99,15~6 were the
initial materials for the production of the alloys. The micro-
structure, hardness, electric resistance, and the dilatometric
analysis of the samples were investigated. From the investi-
gation of the microstructure the authors concluded that the
addition of cobalt does not stabilize the C and heat resistive
solution. The manganese alloys of the ternary system manganese-
co-oper-cobalt (UP to 50% manganese) represent bi-phase mixtures
(t'+ alAn). The hardness of the alloys showed that the ol"-phase
is not stabilized in the manganese-cobalt-alloys with less than
50% cobalt. In alloys with 65 and 70c,'0 manganese and 10% cobalt
Card 1/2 an unimportant reduction of the hardness takes place. In the

case of a further increase in the cobalt content the hardness
is increased and the alloys become extremely solid and brittle.
The determination of the electric resistance was carried out
by means of the potentiometer of the type KITT -1. Comparatively
higher values of the electric resistance occur in alloys with
20-30% cobaltj These alloys are of no practical interest, since
they are not plastic. The dilatometric investigations in the
ternary s stems show that an intermediate phase occurs in alloys
with 5-10~ cobalt which is characterized by an anomalous
expansion in the temperature range of 350-650OC-

claimed that more~than a decade of Investigatiori, testing of flow-
sheets and el6ctrolytic-tank'designs.,utilization of Soviet and non-
Soviet,data, and reverification of published results obtained at the
pilot plant of the U.S-..Bureau of Mines have led to the development
of a definite, and to some extent original, method of obtaining high-
purity chromium. Choice.of a simple, economical flowsheet required
the study of methods for obtaining and purifying compounds of triva-
lent chromium. The most acceptable method, technologically, has
proven to be a two-stage refining of ferrochrome. It is described
in the Introduction by R.I. Agladze. -Compounds of hexavalent c1frorti-
ium are obtained in the first stage by direct electrochemical
dissolution of carbon-containing ferrochrome; in the second stage,
electrolysis of the chromium salts, reduced to the trivalent state,
is carried out. The method is considered significant in view of
the-possibi-lity It affordsof using not only standard ferrochrpme,
but also ferrochrome with a-high content of impurities and a low
chromium content. This feature makes it feasible to use low-grade
chrome ores. Studies are made of the anodic dissolution of ferro-
chrome in sulfate, carbonate, alkaline, ammoniacal, and chromate
solutions. The following methods of reducing hexavalent chromium

compounds are investigatedt the electrochemical method, the action
of sulfur-c.ontain-ing substances, and the Action of materials con-
taining cellulose. Also investigated.are methods of purifying the
chromium compounds of iron, the principal contaminant, by fractional
precipitation of hydroxides, direct precipitation of iron hydroxide,
or solution of ferrochrome In alkaline, carbonate, and other elec-
trolytes. One of the possible processes of obtaining high-pLirity
chrome bydroelectrometallurgically is presented with an accompanying
floW~dheet. The principal components are chromium sulfate, ammonium
sulfate (or chrome ammonium alum), and a certain quantity of biva-
lent chromium ions, which form during the electrolytic process
and whose preservation at a definite concentration is necessary for
stabilizing the process. Carbon-containing ferrochrome isused..as
the raw material for the production of chrome-ammonium alum. -Ammo-
nium bichromate is obtained by anodic dissolution of ferrochror6e in
reusable solutions at a. definite pH value. Iron hydroxide and other
Insoluble residues are filtered off. Industrial water is used for
preparing new portions of the electrolyte. The electrolyte, a so-
lution of ammonium bichromate or a mixture of bichromate and chro-
mate, is reduced in the presence of sulfuric acid with iron filings

or other reducing agents to the complete conversion of bichromate
to chromium sulfate. The eleletrolyte is the 'n transferred to crystal.-
lizing tanks for-crystallization of the chrome ammonium alum. A
small quantity of catholyte, containing bivalent chromium ions, is
added to the crystallizing tanks to speed up crystallization. The
acidic mother liquor is returned to the section for the reduction
of bichromate, and the chrome ammonium alum Is dissolved for the
feeding of the catholyte of the chromium tanks. An anolyte, & mix-

reducing, where it Is reactivAted. A trial run oii an industrial
scale has shown that the process may successfully compete with the
production of chromium by aluminum reduction and demonstrated the
high quality of the product. The studies in this collection and
the proposLad method of producing high-purity chromium are considered
by the staff of the Institute of Applied Chemistry and Electro-
chemistry as just one stage in their work. Investigations of other
methods will be reported In a later volume, The investigators are
studying the possibility of obt-'aining chromium in a single-stage
electrolysis involving solution of ferrochrome and cathodic precipi-
tation of the pure metal in a single tank. For this purpose chlor-
ide and chromic aclid electrolytes are being considered, the latter

TITM On -the Problem of Obtaining Carbonless Chromium Alloys and
Chromium by Electrolysis
PERITODICAL: V sb.: Gidroelektrometallurgiya khroma. Tbilisi, AN GruzSSR,
1959, pp 201 - 219
TEXTS The autbors studied the effect of Fe and Ni concentration in
the electrolyte on the current efficiency, the amount and composition of the
cathode deposit of a carbonless Cr-alloy; they also investigated the
possibility of purifying the electrolyte from Fe and Ni by pre-electrolysis
(for'elektroliz) whereby initially a rich Cr alloy Is being obtained -and then,
pure Cr is produced proportionally to the reduced concentration of substpunces
Introduced in the electrolyte. A mixture of Cr, Ni (100 g/1) and NH4 (100 9/1)

On the Problem of Obtaining Carbonless Cbromium Alloys and Chromium by
Bleotrolysis
sulfates was used as the initial electrolyte. The temperature was 35 - 450C.
The experiments were carried out in cells with diaphragms. It is shown that
in purifying the electrolyte from Fe by pre-eletrolysis a carbonless alloy
rich in Cr is obtained containing 13.5 - 2% Fe. The efficiency for alloy
current is 32 - 40%. The Fe-oontent in the cathode deposit depends on the
Fe c6ficentration in the electrolyte, the acidity of the catholyte and the
time of electrolysis. To obtain electrolytic Cr, containing < 0.5% Fe, the
concentration of the latter in the electrolyte 45;z0.1 g/1, for the deposition
of non-ferrous Cr or Cr with Fe traces it is 0.02 &/1. The presence of Fe In
the electrolyte improves considerably the appearance of the cathode Cr deposit.
The presence of Ni in Cr-electrolyte reduces sharply the current efficiency for
Cr and entails the blackening of the cathode deposit; electrochemical treat-
ment of the electrolyte does not improve the process characteristics. In the
presence of Fe ions, changes in the Ni concentration in the electrolyte within
the limits of 0.1 - 1.0 g/1 do not impair the characteristics of the electro-
lytica.1 process and do not affect the Ni content in the cathode deposit,
