Silver processing Britannica

2020. 8. 13.  The specific extractive metallurgy processes applied to a silver-bearing mineral concentrate depend on whether the major metal is copper, zinc, or lead. From copper concentrates The smelting and converting of copper sulfide concentrates result in a “blister” copper that contains 97 to 99 percent of the silver present in the original concentrate.

Chlorargyrite: The silver mineral chlorargyrite information

Chlorargyrite, despite being an important ore of silver, is not well-represented in collections. This is because of its general lack of aesthetics, with the bulk of mined material being processed for the extraction of its silver content. Formerly called Cerargyrite, Chlorargyrite is the currently accepted name of this mineral today.

The process involves the separation of hydrophobic from hydrophyllic minerals. Flotation has now become the most widely used process for extracting minerals from ores. Designing flotation schemes in a laboratory allows you to optimize the process. Minerals require coating with a chemical to make their surface hydrophobic.

Silver: A native element, mineral, alloy, and byproduct

Silver as a Native Element Mineral. Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals.Unlike gold, it is rarely found in significant amounts in placer deposits. Native silver is sometimes found in the oxidized zones above the ores of other metals.
