• Galena Sphalerite Flotation Separation Method

    Several processes have been developed for the separation of lead from zinc sulphides by twostage selective flotation, but the only method that is employed widely enough to warrant a description in these pages is the one whereby the zinc minerals are depressed by sodium cyanide and/or zinc sulphate, allowing the galena, which remains unaffected ...

  • Cupellation Wikipedia

    Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...
