DLBSTRACT- The work described was bak~ed on theoretical ancl applied work on amalgam methods of separating and producing metals at the chemical-sciences Institute of the AC. SC. KazakSSR (Institut Khimicheskikh Nauk MT KasSSR) and the Kazakhak State University imeni S. M, Kirov (Kazakhskiy gosudarstvennyy universitet im. S. M. Kirova) under the directlon of M. T.

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 Use Of an Amalgam Method for Extracting Thallium from Chimkent Lead Workd Dust 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. There are 5 figures, 13 tables and 10 Russian references. ASSOCIATION: institute of Chemical Sciences of the Ac. of Sc.

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; Card 1/2 0.29%'Pb, 0.05% Cu, 0.55% As, 0.65% Sn, 0.67% Fe, 0.99% Al, SOV/136-58-8-8/27 &-traction of Tellurium and Indiiiin from Antimony Slags. 1.4% S (totall), 0.5% 5 (sulphide), 5.64% SiOg, 10-67% 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. ASSOCIATION: Chimkentskiy svintsov-jy zavod (Chimkent lead smelters). 1. Slags--Properties 2. Indium--Separation 3. Tellerium --Separation 4.

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.

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, S/136/60/000/05/007/025 E071/E235 Industrial Tests of the Vacuo Method of Distilling Zinc From Silvery Foam 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- Card 2/4 'tages. ta) an increase in the recovery of zinc in metal 3/136/60/000/05/007/025 E071/E235 Industrial Tests of the Vacuo Method of Distilling Zinc From Silvery Foam (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 Card 3/4 following works personnel participated in the work: S/136/60/000/05/007/025 E071/E235 Industrial Tests of the Vacuo Method of Distilling Zinc From Silvery Foam S.
