Overview

Silver processing | Britannica

Silver is generally found in the combined state in nature, usually in copper or lead mineralization, and by 2000 bce mining and smelting of silverbearing lead ores was under way Lead ores were smelted to obtain an impure leadsilver alloy, which was then fire refined by cupellation The bestknown of the ancient mines were located at the Laurium silverlead deposit in

Leaching Mining Fundamentals

Leaching is a chemical process in mining for extracting valuable minerals from ore Leaching also takes place in nature, where the rocks are dissolved by water Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained The leaching process in mining is carried out either as heap leaching or insitu leaching Precious metals such as gold are

Chemicals Used in Mining Hesperian Health Guides

· Sulfuric acid is a toxic chemical used in copper mining It is also a byproduct of many kinds of mining, mixing with water and heavy metals to form acid mine drainage Sulfuric acid smells like rotten eggs Contact with sulfuric acid can cause burns, blindness, and death Treatment Chemicals used at mine sites can spill on the skin and clothes, splash in the eyes, or be breathed in as fumes
