The Process Mineralogy Of Gold The Classification Of Ore

Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic solid solution gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold 10 m locked in sulfides.

Ore Pretreatment or Beneficiation. A process step that may precede conventional agitation leaching and possible heap leaching is ore pretreatment, or beneficiation, in order to reduce the quantity of ore that will require chemical treatment. Beneficiation involves separating some of the host rock from the uranium-bearing mineral.
