Studies have been made of electrolytic production of high-purity 
tin. Work has also been done on vacuum refining of tin; in particular, this 
latter method saves associated elements such as lead and bismuth that were 
previously lost in processing. This vacuum-distillation-refining process 
both shortened the time of refining and cut production costs at the 
Novosibirsk Tin Plant. 
Studies on the selection of optimum charges in copper reverberatory 
furnaces increased productivity 15 to 20 per cent. 
In scientific work done on the complete conversion of copper and 
polymetal ores, attention is also paid to the introduction of new pyrometal- 
lurgical and hydrometallurgical methods, and also to the improvement of the 
smelting of copper, lead, zinc, and polymetal concentrates, as well as 
intermediate products. 
During 1958, the Institute of Metallurgy and Ore Beneficiation, in 
cooperation with the Power Institute, also a member of the Academy of 
Sciences, Kazakh S.S.R., continued its work on the theory of the relatively 
new cyclone smelting processes. Copper concentrates were successfully 
smelted in a cyclone chamber of the Balkhast Copper Smelting Plant; 
production increased by a factor of 1.5 to 1.6. It was established that the 
process was very efficient compared with conventional methods for smelting 
copper. Laboratory research has also been completed on cyclone smelting of 
Tekeliysk intermediate products, Leningorsk slags, Ust-Kamenoyorsk zinc 
concentrates (KeK), and Achisaysk oxidized lead-zine ore. It is also 
hoped to utilize this new cyclone smelting process in ferrous metallurgy. 
The Institute publishes a Trudy frequently, and offers courses in 
ore dressing, ferrous metallurgy, rare metals, chemistry, and nonferrous 
metallurgy.
