University imeni S. M, Kirov (Kazakhskiy gosudarstvennyy

of the Chemical-sciences institute of the AV YazSSR. Sintering.
dust analyses for different periods are tabulated (T~Lble 1) and
laboratory-scale experiments with the dust are described. Here,
roasting of 20-25 kg batches was carried out at ~ 400 - 500 o C,
showing (Fig. 1) that an appreciable part of the sulphide sulphur
and thallium is eliminated within the f'-rst hour at 4000 C.
Four-fold beaching of the dust (two 250-9 smaples) with water
at 80 - 90 C showed (Table 3) that 80-90% of the thallium was
extracted in the water, the extraction increasing with tempera-
ture. Cementation of thallium with zinc amalgam was carried
out on the acidulated extract which was continuously circulated
(Fig. 3): the results (Table 4) showed that 98-99f extraction
of thallium from the solution could be obtained. It was shown
that the amalgam (ori inally 0.36 - 0.40 g/litre Zn .127
g/litre Cd and 108 mg~litre Tl) could be decomposed y anodic
oxidation with special electrolytes at current densitiees of
100 - 50 A/m2, the density being gradually reduced as the
appropriat-e metal was removed from the amalgan. The flori-sheet
based on the laboratory results (Fig. 4) was put into practice in
a lari:er scal~e ple-at (Fig. 5) at the Chimkensk Works, where it

treated several tons of dust from April to October, 1956, and
was used for balance experiments in October of that year. The
article gives details of the different stages and balances for
the different metals. These show that with the proposed
method pure metallic thallium can be obtained with a yield of
6%, about 30% being in returns and 5% being lost. An edit-
orial note invites discussion on the amalgam method.

TITLE: Extraction of Tellurium and Inditun from Antimony Slags
(Izvlecheniye tellura i indiya iz sur'Myanistykh shlakov).
PERIODICAL: TsvetnyyeMetally, 1958, Nr.8, pp.34-39 (USSR)
ABSTRACT: The authors have previously shown (Ref.1) that at the
Chimkent lead smelters the tellurium-content of the
slag from re-smelting of sodium antimonate can reach
0.2-0.8%. Since th-!se slags also contain indium the
authors carried out work to determine the nature of the
distribution of this element in the various products of
the lead industry (Table 1) as a preliminary to the
development of a process to recover it and tellurium.
It was found that the indium tends to concentrate in the
dry dross during de-coppering of crude lead. This dross,
dusts from the shaft smelting of sinter or circulating
materials or antimony slag could be used for indium
ret,overy. The last material, obtained from a pilot-
plant, was chosen,, its composition being 9.6% Sb;

NaOHY 54.65% Na2CO3, 0.3-0.4 Te. 0.01-0.02% In. It was
fo-.Jlid that tellurium and indium stay in the solid residue
(Table 2). lkftar a sulphatizing roast at 280-300'DC the
indium can be leached out by water at 85-90 C but the
tellurium is practically insoluble. Based on this a
flowsheet (Fig.) has been devised which gives elementary
tellurium (by caustic-soda leaching of the insoluble
residue from the indium leaching, followed by electrolysis)
and an indium concentrate from which metallic indium, can
be obtained. There is 1 figure, 5 tables and 4 Soviet
references.

ABSTRACT: The Chimkentskl,y svintsovyy zavod (Chimkent Lead Works)
was bullt In the fJ.r3t fIve-year plan and produces lead,
copper, bismuth, antimony, noble and rare metals as well
as lead objects. The works was reconstructed in 1949-
1955 without production delays; eg sinter handling was
modernised7 the shaft furnaces reconstructed, a hydro-
metallurgical plant was built and the works pioneered in
the use of high-velocity turbulent dust-catchers (which
proved very success:021 but are still being improved).
Teams from the G'protsvetmet7 Gintsvetmet and Institutes
of the AN Xaz SSR (AS Xaz SSR) as well as A,K, Simakov,
formerly works director and now president of the
Vostochno-Kazakhstanskiy sovnarkhoz (East Kazakhstan
economic-council), participated. Extensive work is now
proceeding on mechanization and automation: compressed

bunkers, the sinter-plant transportation control system
has been improved and trials of an electro-vibro conveyor
for finished sinter have given promising results. The
works was the first in the USSR to adopt continuous
tapping of products from the smelting furnace and up.-
draught sintering, pre-pelletizing of the sinter mix,
semi-automatic smelting furnace charging, slag treatment
by the pulverized-coal injection method and continuous
refining are to be adopted in the next few years. The
author names some noteworthy personnel and the honours

TITLE: industrial Tests of the Vacuo Method of Distilling Zincpl-
From Silvery Foam
PERIODICAL: Tevetnyye metally, 1960, Nr 5, pp 31-38 (USSR)
ABSTRACT: In 1955 on the Chimkent lead works, Pilot plant tests of
vacuo distillafl-onof zinc -from silvery foam (60.3% Pb,
26.3% Zn, 99.564 kg/t of noble metals, including a
little gold; 0.3% Cu) were successfully completed
(Ref 2). Later, an industrial plant was designed,
testing of which during 1958 to 1959 is described. A
sketcn of the side view and the longitudinal cross-section
of the vacuo furnace is shown in Fig 1 and a schematic
diagram of the whole installation in Fig 2, The operating
principle of the furnace is similar to vacuo-separating
furnaces used in the titanium industry for distilling off
magnesium and magnesium chloride from titanium sponge.
During testing, the installation was somewhat modified;
its final design is outlined. The capacity of the furnace
Card 1/4 is 1.0 to 1.5 tons per charge, 2.7 to 3,6 tons per day,

the power consumption is 9? W, At a temperature of the
process of 9200C and a residual pressure in the retort
of 1 to 2 mm. Hg, the following results were obtained.
The yield of products, %: lead 58, condensate 25, dross
12.5. The distribution of metals,.-%: zinc in condensate
89.3, in dross - 8.?, in silvery lead - 2; lead and
noble metals in silvery lead - 82.9 and 81,6, in dross
11.8 and 14.1 and into condensate 5 and 4 respectively.
Metal balances of some heats are given in Tables 1, 2
and 3; a comparison of the yields of products obtained
by the usual and vacuo distillation is given in Table 4;
a similar comparison of the chemical comp6sition of
distillation products is given in Table 5 and of the
recovery of metals, in Table 6. A comparison of the
results previously optained on the pilot plant with the
results obtained on the present installation is given in
Table 7. It is concluded that
in comparison with the usual
process the vacuo distillation has the following advan-

(20%) at the expense of producing lead and dross, with
a lower zinc content, the further processing of which will
ijivolve lower losses of noble metals; (b) a decrease in
the yield of dross by a factor of 1.5 and a decrease in
the transfer of noble metals and lead into the dross;
(c) an increase in the recovery of noble metals and lead
into silvery lead; (d) an improvement in sanitary-
hygienic conditions of working, The branch of Gintsvetmet
for technical and economic investigations carried out a
comparative evaluation of the existing, vacuo and electro-
the--mal (used in UKSTsK) meth-ods of distillation of
zinc from silvery foam which Indicated that the vacuo
method is the most economical. An order was placed with
OKB Electropech and Works producing electro-thermal
equipment for the degi-gn7and construction of electrovacuo
furnaces capable of dealing with the whole throughput of
the Chimkent Works, In addition to the authors the
