ABSTRACT: Utilizing the case of an Al bath as an example, the authors analyze
the significance of the heat of dissolution of raw materials intro-
duced into the bath in batches and the significance of an increase in
electrical potential occurring in the bath during periods between
charging on energy-balance equations for an electrolytic bath. In
computing variations in heat content of a system undergoing an
electrochemical reaction, e.g.: AI?03+1-1/ZC -2AI+1-1/ZC02,
the right-hand side of the equation must show the Al?.03 in the form
in which it is introduced into the bath rather than in the form of
A12_03 already dissolved in the electrolyte. In computing the ener-
Card I /Z gy balance, the alumina (A) must appear in the same form as that

SOV/1 37- 59- 1-460
On the Effect of Periodic Charging of Raw Materials on the Energy Balance (cont. )
in which it appears in the material balance. An increase in the electrical potential
of the bath, which occurs as the concentration of A in the electrolyte is reduced,
results in the consumption of an additional quantity of electrical energy Q9, if
the increase in potential is brought about merely by a change in the concentration
of A, then Q 9= AZ , where AZ is the change in the isobaric -isothermal potential
of the system. If cFther causes Aso are active, the magnitude of the AZ p will be
fully compensated by the electrical energy supplied externally. The magnitude of
the Q will be the sum of two items: Qg = A Zp+ Q' , where Q' represents the addi -
tionaTcluantity of electrical energy consumed in the bath as a result of an increase
in the potential due to any causes aside from a change in the concentration of the A.
Being a separate item on the input side of the energy-balance equation, the heat of
dissolution of the raw material in the electrolyte must not be taken into considera-
tion. A method permitting computation of the mean increase of potential in elec-
trolkzers operating with raw material introduced periodically is given together with
the computation of the mean value of the potential increase in an Al bath (this value
being 0.105 v in said instance). In computing variations in the heat content of a
system undergoing an electrochemical reaction the output side of the balance equa-
tion must be based on thermodynamic data for solid rather than dissolved A-

ABSTRA.CT: The accumulation of sulphur in the aluminate solution in
the leaching of bauxites leads to Increased irreversible losses
of alkali and can have a deleterious effect on the decompois-
ition and other aspects of the process. Ia this article an
account is given of the study of the kinetics of sulphur
extraction Into the solution during leaching of bauxite by
Bayer's method and the influence on it of various factors. The
leaching was carried out in 80 ml laboratory autoclaves the
aluminate solutlons containing from 120-137 g/litre Al 6 and
from 326-335 g/litre of ffa20total- In all experimentsqe
leaching was carried out on diasporic bauxites containing
50,0 - 55-3% Al 0 and 0.25 - 1,9% S, the bauxites being ground
Coad 1/2 to 75% through i78mesh. Lime was added to activate theoleach-
ing, and all experiments were carried out at 200 - 205 C. The
extraction of sulphur is plotted against the duration of

leaching for various conditions and against the silica content
in the bauxite. The experiments were carried out under
conditions rather similar to those prevailing in practice and
the results axe considered to give a useful'indication of the
influence of the sul hur amtent in the bauxite and in the
alumina solution ta part in the leaching on the degree of
extraction of sulphur. As regards the influence of silica it
is suggested that the sulphide sulphur extracted from the
bauxite reacts chemically with the silica to form compounds

of aluminate solutions at the deconposition process in various
industrial regimes is shown. It is found that these properties
change very little in the decomposition process. They my be
assumed without any great error to be constant in the conplete
duration of the process with the exception of the initial period.

TITLE: Properties of Aluminate Solutions (Svoystva alyuminatnykh
rastvorov)
PERIODICAL: Tr. Ural'skogo politekhn. in-ta, 1957, Nr 58, pp 36-50
ABSTRACT: A study is made of the properties of aluminate solutions for
density, viscosity, electrical conductivity (C) and surface ten-
sion. Subjected to the investigation were solutions containing
-30-320 g N?
,99otal /liter and 15-320 g Al 203 /liter, with a
basicity of 1.48-3.53. The solutions are made by dissolution of
grade Aoo Al in chemically-pure caustic. These properties of
the aluminate solutions are measured at 30, 40, 50, 60, and
0V %.,. Density is determined by pycnometer, viscosity by the
Ostwald viscosimeter, and electrical conductivity by the
Kohlrausch bridge. Surface tension is determined by the method
of maximum pressure of air bubbles (the "Rebinder" instru-
ment). An investigation of aluminate solutions of various molar
Card 1/2 Na 20total Al 203 ratios in accordance with strength show that

SOV/ 137- 57-10-18787
Properties of Aluminate Solutions
at first specific C rises with Na2O concentration, attaining a maximum at
90-140 g Na2Ototal/ liter, and then declines. The molar C of aluminate solu-
tions drops smoothly as concentration rises. Molar C decreases with in-
creasing A1203 concentration in the solution. As temperature *rises, the C
maximum shifts toward higher concentrations. The viscosity of aluminate
solutions containing up to 100 g Na 20total /liter at vari )us A1203concentra-
tions is virtually the same as the viscosity of NaOH solutions of the same
strengths. The high values of the molar C of aluminate solutions and the low
values V the energies of activation bear witness to the fact that the predomi-
nant Na solutions in dilute solutions are also accompanied by a smaller
amount of OH-. Viscosity is determined primarily by the large. and sluggish
aluminate anions. As temperature rises, the density of the alurninate solu-
tions shows a linear decrease. In dilute solutions, the energies of activation,
1Ej and c are 400-700 cal/mole, while in strong solutions they differ and
depend upon the Na?O:AJ 0 ratio. Surface tension rises with concentration
2 3
and drops as temperature rises.

ABSTRACT: The structure of aluminate solutions was investigated by
means of the ultramicroscopic method. These investigations
showed that the alumirate solutions do not contain submicrons.
The behavior of the aluminate solutions in the decomposition
process was investigated by ultramicroscopic observations
according to the influence exerted by diverse additions, as
e.g. aluminum salts and colloidal aluminum hydroxide.
The heterogeneity of the solutions highly increases on the
addition of aluminum gel to the aluminate solutions. A high
concentration of submicrons occurs, which further agglomerate
into micro- and macro particles, as well as an intense de-
composition of the alumim to solution under the formation of
highly dispersed hydrargillite.

as well as new concepts of the growth of the hydrargillite

ABSTRACT: The author replies to Lyapunov's criticism (Tavetnyye Metally 1957
Mr.7) of points in two of his papers on reasons for the periodical
size reduction of aluminium hydroxide in the decomposition of aluminate
solutions. He presents results of additional experiments (in which
V.A. Derevyankin participated) on the decomposition of a solution
(132.5g total'Na2O and 125.2g A1203 per litre) with coarse-grained
primer, the sizing of the product being tabulated. This showed that
many new small crystals are produced, thus confirming his previous
statements. He refers to eleetron-microseopic studies which showed
the appearance and growth of dendrites at isolated points of the
surface of hydrargillite crystals and deals with the heat effect of the
hydrolytic decomposition of sodium aluminate. Ile agrees with Lyapunov
that the heat effect on the surface of growing particles due to the
beat of crystallization is small, but denies that this beat has no
influence on the growth and relates this to the "wave" mechanism of
crystallization established by O.M. Ansheles, V.B. Tatarskiy and A.A.
Shteynberg (ref.12). He indicates an error in Lyapunov's treatment of
the crystal-boundary temperature and defends his own recommendation

initial and final decomposition temperature. In support of his
recommendation he cites experience at the Urallskiy (fig.2) and
Bogoslavskiy (fig.3) aluminium works. The latter contradicts
Lyapunov's attribution of size changes to temperature changes.

of one of the causes of the reduction of the size of the crystals.
With an increase of the temperature of the aluminate solution up

is kept in the parent solutions for some time, baydrite is
found in the precipitation prodraots of this hydroxide. 2) The

ABSTRACT: Tais is the firot article of a series devoted to study
of different aluminum hydroxides and oxides on the rate
of decomposition of aluminate solutions. Decomposition
of the aluminate solutions with seed crystals of
boemite and diaspore was studied in this article. The
starting aluminate solutions were prepared from "pure"
brand aluminum and chemically pure NaOH. The amount
of A12 03 in these solutions was 120-135 g/liter and that
of Na20 gen.' 122.5-144 g/liter; Na2okst, 1121-131 g/literj.:

aluminate solutions varied from 0 to 2%. The foil 'owing
seed crystals were used: boemite obtained by roasting
hydrargillite at 300P for 3 hours, henceforth called
thermal boemite; boemite obtained by hydrothermal
recrystallization of hydrargillite at 3000 for 8 hours;

small amount of seed crystals (the seeding ratio 0.05

they are composed'of hydrargillite and seed crystals

sis of the precipitates obtained during the decomposition

with aluminate solutuion 18 transformed first into '

tion of boemite Into diaspore, compared to hydro-
thermal boemite, is due to the partially distorted
crystalline lattice of unrecryatallized boemite, the
outer layer of which is transformed at first into ; ,
bayerite and then into hydrargillite. The induction
periods (as it is shown on the decomposition kinetics
curves) is due to the recrystallization of the outer

of the formed crystals taken with an electron microscope
are given. It was concluded that diaspore is inactive

ABSTRACT: This Is a contibuation of studies (Abstract 77626) on
the rate of decomposition of aluminate solutions under
the influence of added aluminum-oxide grains. This time,
the authors used -alumina and corundum seeds,and the
transitional products between the two, to accelerate
aluminate decomposition by growing crystals. The
three types of seeds were produced on annealing
hydrargillite at 8000 C for 4 hr, diaspore at 1,200 0 C
for 5 hr, and hydrargillite at 1,100 0 C for 12 hr,
respectively. Figures I and 2 illustrate the seeds of

effectively accelerate the decomposition of dis-
solved sodium aluminate after a certain period of
induction, while corundum does not affect the
aluminate decomposition during any duration. The
Induction period decreases with the increasing
quantity of the seeds relative to that of the alu-
minate solution, i.e., with the seeding ratio.
Organic tmpurities first reduce the decomposing power
of I '-alumina, but later increase it considerably.
The decomposition of aluminates by '-alumina gives
rise to the precipitation of extremely fine aluminum
hyd'roxide. Up to 30% of the grains remain smaller
than 40 . . Small amounts of organic impurities
increase this fraction up to even 70%. However, the
higher contents of organic substances make the hydroxide
slightly coarser. Larger quantities of seeds (seeding
ratios 0.2-0-5) also reduce the grain size of the
hydroxide. The precipitate, generated by the
transitional products from alumina to corundum,
Card 2/6 consists of up to 25% of the fraction under 4o I

then into hydrargillite. Electron microscopic data
disclosed the composition of of amorphous
minute particles, whose porous aggregates have large
surfaces per minute volume. During the induction period
they become covered with dendritic crystals of boehmite
and hydrargillite, 0.1-0.5 : long and 0.1.~,. across,
whose crushing off at stirring of the solution produces
numerous new -crystallization centers. Some of the fine
grains of .'-al=ina recrystallize into hydrargillite
completely and form pseudohexagonal Dlatelets. In
conclusion, the authors state that the seeding capa-
city of boehmite and ' -alumina is related to their
Card 3/6 instability in the presence of hydrargillite.

TITLE: Effect of addit1ons of titanf4m oxide and silica on
the leaching rate of aluminum hydraxide

TD,XTt The main part of this article deals with tble study of kine-
tics and the nature of dissolving pure aluminum hydroxide in the
presence of titanium and silicon oxides. To establish the nature
of dissolving thecrystals of hydroxide use was made of electron
microscopy, by which means data was obtained on the formation of
protective surface films on hydroxide crystals and also on the
form of traces of chemical compounds, developed by the reaction of
Ti and Si oxide with an alkaline solution of aluminum during leach-
ing. The composition of these compounds were not studied. For
leaching experiments following aluminum hydroxides were used: 1)

Hydrargilite? obtained under control conditions; 2) Bemite, prepa-
red by the recrystallization hydroargilite under hydro-thermal
conditions at 3000C and for 8 hours; 3) Dia8por, prepared by the
method of A.W. Laubengayer and R.S. Weisz (Ref. 6: J. Am. Chem.
Soo. 65, 247, 1943), i.e. by beating bemite in presence of water
at temperature 350-3750C with 2 % of diaepor seed. The results of
the experiments confirmed that titanium oxide appreciably lowers
the leaching rate of diaspor and bemitep but has no effect on the
dissolving rate of hydroargalate. It was also confirmed that tita-
nium oxide inhibition at a temperature of 1500C and higher pre-
vents the leaching of bemite and diaspor~'but on reaching 2300C it
no longer prevents the leaching rate of bemite while the solution
of diaspor is still inhibited. In this respectp T102 gel and ru-
thile differ, the latter being less active. In the presence of
waste (3-4 % of the initial weight of solid phase), the inhibiting
action of titanium oxide is much smaller and at temperatures above
1750 becomes practically zero. The oxides of silicon also deter
the leaching of aluminum hydroxide# but to a lesser extent than ti-

tanium, oxide. The best inhibitors are silica gel and opal. Elec-
tron microscopy has confirmed NaK. Druzhinina's suggestion on the
mechanism of the inhibitive action of titanium oxides# i.e. the
formation of protective films on aluminum hydroxide. The thinness
of film is appreciably less than 100 1 and on the addition of
waste films wero not formed, With an increase in leachin4 time#
the protective films crystallize into needle-shaped crystals which
still form protective layers, but now these are porous and alka-
lies diffuse to aluminum hydroxide and the dissolving rate is high-
er. Additions of silicon oxides form crystalline protecting films
of sodium aluminum silicates on aluminum hydroxide insulating it
from alkaline attack. The formation of aluminum silicates on the
surface of aluminum hydroxide crystals can be explained In the
following manner: Silicon compounds contained In bauxite react
with alkaline aluminum solution to form sodium silicate which in
turn, reacts with sodium aluminate to form a complex compound ga,20-
A120 -2SiO2 2H20. The form of reactionj state the authors, is pro-
babli.

The equilibrium of the above reaction Is displaced to the right
since sodium aluminum silicate is fairly insoluble in aluminum so-
lutions especially of low or medium concentrations. The best condi-
tion for above reaction to take place is at the surface of bauxite
particles. There are 4 figures and 7 referencess 6 Soviet-bloc and
