Description: 
Probably no area in the world has such large deposits of chromium 
and vanadium as the Kazakh S.S.R. New deposits of iron, copper, aluminum, 
lead, and zinc are continually being discovered. The Kazakhstan deposits 
of copper, lead, zinc, cadmium, silver, tungsten, and molybdenum are the 
largest in the U.S.S.R. There are also rich deposits of manganese in the 
region. It might be said there probably are few chemical elements that 
could not be found somewhere in Kazakhstan; despite this, however, the 
Kazakh S.S.R. still accounts for only 16 per cent of the industrial produc- 
tion of the U.S.S.R. For this reason, considerable attention is being paid 
by the Institute of Metallurgy and Ore Beneficiation to the development of 
methods for the complete extraction of all valuable components from the 
nonferrous and ferrous ores of Kazakhstan. 
Studies conducted by the Institute have concerned the ore- 
concentration properties of slags; extraction of arsenic from speiss; 
recovery of numerous rare metals from smelting dust and slags by leaching 
and hydrometallurgy; electrolytic precipitation of lead and zine and drying 
of lead-zine concentrates; concentration, extraction, and electrolytic 
refining of rhenium; obtaining lead-calcium alloys by ecarbide-thermal and 
electrolytic methods; hydrolysis of chlorides and nature of complex lead 
compounds in chloride solutions; extraction of vanadium and manganese from 
phosphide ores; and hearths for open-hearth furnaces. Studies also have 
been made of the use of radioisotopes in metallurgy, new solvents of rare- 
metal compounds, kinetics of solutions, vibro-inertial grinding equipment, 
nonferrous metallurgy slags, and ore flotation. 
The Institute has also studied principles and processes of working 
mercury mines and high-speed sinking of shafts, and new methods of smelting 
nickel oxide ores. Analytical studies have been conducted on the deter- 
mination of arsenic, tellurium, and selenium in ores. Investigations have 
been made of physico-chemical properties of foam glass. 
The Institute also has the task of studying problems pertaining to 
the distillation of compounds of rare metals from aqueous solutions. 
The Institute develops complete flow sheets and methods for the 
conversion of raw materials by different methods. Flow sheets are being 
developed that may eliminate the loss of valuable metals in slags and 
tailings. Work is progressing on a more complete extraction of dispersed 
elements from intermediate products, i.e., extraction studies on indium, 
selenium, germanium, gallium, rhenium, cadmium, thallium, lead, zinc, and 
other metals. New flow sheets are being worked out on the Koynakly copper 
deposits and major deposits of rare metals. Flow sheets for the Tugay 
bauxite ores and for the flotation of the Tekelin lead-zine ores have been 
developed. 
Work also has been done on the development of methods for producing 
aluminum from new types of raw materials. The technology for the production 
of titanium and vanadium has been investigated.
