5 Key Steps in the Lead and Zinc Ores Extraction Process
Lead Ores. Lead is primarily extracted from the mineral galena, which is lead sulfide (PbS). Galena is the most important lead ore and is often found in association with other minerals such as sphalerite (zinc sulfide), pyrite (iron sulfide), and silver. The presence of silver in galena makes it a valuable source of both lead and silver.

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 tool to understand the …
