Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …

Flotation. This is a partly physical and partly chemical beneficiation used to concentrate ores of copper, lead, and zinc. These metals have considerable affinity for sulfur. (the table on the metallurgy section lists sulfide ores for each of them.) The ore is ground and suspended with water in large tanks.

Processing of the Kipushi Cu–Zn sulphide ore started in 1935. Initially, the plant treated about 20,000 tonnes of ore per month using a single flotation circuit with conventional reagents such as xanthates and pine oil. Over the period 1937 to 1940, the concentrator was extended to allow the differential flotation of Cu–Zn.
