Innovative technologies for processing tungsten containing tails of the enrichment factory of Zhambyl

Achievements and current state of technology for processing of technogenic materials have been assessed. The goals and objectives of the research have been defined. New laboratory apparatuses for processing mineral raw materials have been developed and manufactured. Laboratory and experimental industrial research of methods of circulation concentration, flotation classification, electrochemical chlorination, turbulization centrifugal separation have been carried out. The methods efficiency was assessed. The results of study of physical and chemical properties and distribution of metals by size classes of tungsten containing tailings are given. Studies of tailings enrichment by gravity, flotation and electrochemical enrichment methods are carried out. It is shown that for preliminary processing it is rational to use the method of circulation concentration. The methods of flotation classification, molybdenum flotation of a collective concentrate, electrochemical leaching of copper from a concentrate from flotation classification, turbulization centrifugal separation of products of tin flotation have been investigated. The innovative technology has been developed for processing complex tungsten containing tailings, based on research on a sample of tungsten containing tailings in the Zhambyl enrichment plant of the Kara-Oba deposit. This technology opens wide opportunities for processing of technogenic products and is offered for industrial implementation.
