Beneficiation of silver and silver-bearing lead-zinc ores: A …

Silver (Ag), atomic number 47, is a rare metal resource with dull-white color. In nature, most of the silver resources are associated with Lead-Zinc ores, except for a small portion in the form of simple substance or silver minerals. Therefore, the acquisition of metallic silver is relatively difficult. Flotation is the principal beneficiation method to concentrate silver …

Coal beneficiation: theory and practice

Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash reduced when the −500 mesh material was removed.
