and beneficiation. They have designed and perfected numerous innovations 
for fluidized roasting furnaces, including equipment for their cleaning and 
cooling, electrothermic methods for electric melting, furnace filters, 
sintering, cyclone processes, and mechanized pig casting. 
They cooperated with other groups in 1959 to develop automation for 
the Bessemer process. They have also done research on the structure and 
mechanical properties of bronzes, the theory of bimetallization, and the use 
of various alloys for the manufacture of secondary electron emitters. 
The Institute has several branches scattered across the U.S.S.R. 
The Armenian, Leningrad, and Siberian Branches of the Institute serve their 
respective economic areas through research in mining, ore dressing, and 
smelting. The Altay Branch has also designed units for the improvement of 
zine extraction, while considerable research on the automation of furnace 
charging and casting has been done at the Caucasian branch. 
The Kazakh Branch has been active in cooperative plant testing of 
cyclone melting and the smelting and leaching of various nonferrous metals. 
In 1956, the Siberian Branch, consisting of 10 departments, was established. 
It does the planning for new establishments and reconstruction of the old 
nonferrous industry in Siberia, the Urals, and Kazakhstan. 
Located in Tashkent, the Uzbek Branch, in 1959, drew up the plans 
for an experimental plant and quarry for graphite. It has also worked on 
automation and reconstruction of smelting plants. The Ukrainian Branch 
was established in Zaporozh’ye in 1959. They worked on the plans for the 
first powder-metallurgy plant in the Ukraine. 
The Institute periodically publishes a Trudy.
