gold sulphotellurides, and gold sulphoselenides. Gold that is invisible under optical and scanning electron microscopes is referred to as submicroscopic gold (or invisible gold) and is the major form of gold in refractory gold ores such as Carlin-type gold deposits, some epithermal gold deposits, and volcanogenic massive sulfide (VMS) deposits.

Gold Extraction from Different Types of Ore

Jan 10, 2020 Telluride gold ores generally refer to ores containing natural gold and sulfide minerals, which have high economic value. Gold extraction from this type of ore can be different, because whether this ore contains silver or not, it dissolves very slowly in cyanide solutions, so a pre-oxidation stage is usually added before cyanidation. 11.

The process mineralogy of gold: The classification of ore

Up to10%cash back 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 in sulfides. Other types of problem gold ores include copper-gold ores and preg-robbing carbonaceous ores.

The Source of Gold Its Ores and Minerals

General Types of Gold Ores: Gold deposits are often classified according to their association. The first of these may be catalogued as quartzose. This implies that the gangue mineral is acid, that is, quartz, and that fluorite may abound, or even the other gangue minerals of the alkaline earth group.

Gold extraction

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s
