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.
