5 Key Steps in the Lead and Zinc Ores Extraction Process
1. 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.
