The process mineralogy of gold: The

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 µm) locked

Abstract. The copper-gold ore deposit at Gedabek in western Azerbaijan is described, together with the various processes that are used to extract the gold, silver and copper from these ores. The processes include heap leaching, agitation leaching and flotation.Geometallurgy is used to classify the various types of ore found in this complex ore body and to determine the optimum processing route for each ore type. Examples of the ore

Processing, smelting and refining gold | World

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are
