Complex and nonsulfide leadzinc 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 tool to understand the flotation behavior of these ...

General1 Leadbearing ore is mined from underground or open pit mines. After extraction, the ore is processed by crushing, screening, and milling. Domestic lead mine production for 1991 totaled 480,000 megagrams (Mg) (530,000 tons) of lead in ore concentrates, a decrease of some 15,000 Mg (16,500 tons) from 1990 production.
