silver sulfide ores

    Lead-Zinc ores - Danafloat - Home- silver sulfide ores ,Lead-Zinc or Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena .The Mineral Gallery - Sulfides ClassThe Sulfide Class minerals comprise an economically important class of minerals Most major ores of important metals such as copper, lead and silver are sulfid Strong generalities exist in this class The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored ,.
