Gold Ore - an overview ScienceDirect Topics
In this process, three main reactions occur: the litharge is reduced to lead, which collects almost all of the gold, silver, and platinum group metals to form lead bullion, while the pyrites decompose to form ferrous sulfide and sulfur, which converts copper present into copper sulfide or matte, and the fluxes combine with the nonmetallic components of the charge to form slag.

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 ...
