Concept of metal leaching in disintegrators

Disposal of stocks of tailings from metal ore processing has become one of the main problems of mining. It brought to life the problem of extracting metals from utilized tailings, without which recycling is both economically and environmentally unacceptable. This explains the relevance of the new concept of leaching of metals in activators. The aim of the research of this direction of mining is to justify the technical feasibility and economic feasibility of using metal-containing raw materials for waste as raw materials for the manufacture of commercial products. Investigate the possibility of extracting metals to a safe level by mechanical or other effects for the use of secondary tails. The data on the leaching of tailings in the disintegrator are presented. A reference is given on the chemical composition of tailings for the processing of polymetallic ores. The study regulations are described. The results of leaching of tailings in the disintegrator are summarized. The graphs of the interlinking of the parameters of leaching of metals are presented. Comments are given on experimental dependencies. The leaching in the disintegrator compared with agitation leaching increases the recovery of metals and reduces the processing time. The usefulness of the effect of mechanochemical activation is enhanced by the modernization of the design of the disintegrator.

Keywords: metal ores, processing tailings, tailings processing, leaching, disintegrator, binder, extraction, parameters.
