Description: 
GINTsvetmet, organized in 1930, concentrates on research pertaining 
to nonferrous ores and their products and the development of control methods 
applicable to the processing and quality of the finished products. MInvesti- 
gations on zinc, copper, and lead (especially high purity) are quite extensive. 
The work on flotation processes has included studies of amines for use as 
possible flotation reagents. Roasting, smelting, vacuum melting, and other 
processes have also been investigated and improved. 
Various staff members have cooperated with plant staffs on automa- 
tion studies. For example, they worked out projects for the complete auto- 
mation of a copper factory and automatic fluidized roaster control. 
Their research on analytical methods has included work on improved 
spectral methods, including the development of an automatic flame spectro- 
meter. In fact, they produce and distribute spectral standard samples to 
other institutes. Utilization of radioactive isotopes for the development 
of chemical methods of analysis has resulted in a simplified method for 
determining minute quantities in mixtures, known as the "method of multi- 
radioactive dilution." 
They have also done research on the improvement of the production 
of semiconductor materials, especially selenium and tellurium. 
The Institute grants the Candidate's Degree. 
Collections of staff reports are irregularly published by the 
Institute.
