Study of kinetics of FeSiO3 compounds from copper enrichment factory waste.

Аннотация

The article presents the processes of reducing waste generated by metallurgical enterprises, finding solutions for waste-free technologies, and creating effective technology in the future, while cleanin the environment from harmful waste is one of the most urgent problems. Collected waste in the 1st copper enrichment plant of the Almalyk Mining and Metallurgical Combine in the amount of 460 million tons, the content of precious elements is as follows: Cu - 0.12-0.08%, Au - 0.3 - 0.4%, Ag – 1.2-1.4%, Fe – 5.28-4.93%, Al2O3 – 11.9-12.26%, SiO2 – 69.53-69.08%, therefore, the waste generated from the enrichment process cannot be disposed of directly as waste. First, carbon can be used to recover iron from the waste, but this does not allow the iron to be extracted from the complete mineral composition.
