Development of enrichment reagent regime of Py-Cu-Zn ore using collectors’ mixtures

Abstract

The article presents results of flotation enrichment of pyrite-copper-zinc ore in a selective mode. It allows predicting the choice of technology for enrichment of non-ferrous metal ores based on mathematical models describing the influence of hydrodynamic and reagent modes on the flotation parameters of the ore under study. The use of a mixture of flotation reagents excludes the use of special foaming agents in the process of selective flotation enrichment because the function of foaming agents and collectors is performed by flotation reagents. At the same time, an increase in the yield of the concentrate and the degree of metal extraction into the concentrate is achieved, and an increase in the selectivity of metal extraction and the degree of flotation enrichment of polymetallic ore. As a result of the processing and analysis of data on the flotation collective-selective enrichment of pyrite-copper-zinc ore, there have been developed recommendations for the technological evaluation of the choice of a selective reagent mode of flotation enrichment of ores.
