摘要
Analyzing the state of the raw staff market of tungsten shows that, despite the presence of a large raw materials base in Russia, the average content of tungsten in ores is low, which determines not only the quality of concentrates but also the economic indices directly connected with choosing the methods for opening and hydro-metallurgical processing. The development of sorption processes with a view of improving the ecological situation at enterprises of the branch is shown to be required along with the use of the traditional methods in tungsten hydrometallurgy. The sorption method of purifying from the molybdenum admixture is the most expedient method for processing tungsten concentrates.
