Apr 03, 2020· Lead is commonly found in deposits with other minerals, such as silver, zinc or copper. Once the lead ore is brought to the surface, it goes through a series of refining processes that separate out the different metals contained in the ore. For example, U.S. mines in Alaska and Missouri are zinc and lead operations.
All was not solved, however, for two problems persisted. Froth flotation was still unable to separate zinc from silver-lead conglomerates.
