Description: 
Irgiredmet is the center of nonferrous metallurgical development 
in Eastern Siberia. The majority of the Institute's research projects have 
dealt with the establishment and improvement of concentrating and processing 
methods for the extraction of tungsten, molybdenum, titanium, aluminum, 
lithium, beryllium, zirconium, columbium, tantalum, gold, tin, indium, 
copper, strontium, and diamonds. They have also developed quantitative 
spectral-analysis methods for controlling the production of rare elements 
from raw materials. Gallium, germanium, columbium, titanium, zirconiun, 
and indium have been successfully determined by these methods. 
The Institute is responsible for the preparation and distribution of 
standard samples for use by other laboratories in the spectral analysis of 
steels, cast iron, and iron alloys.
