Physical Separation Of Gold Ore In Viet Nam

Nov 03, 2015 The formation of gold deposits on Earth requires aqueous fluids that extract gold from minerals and magmas and transport and precipitate the metal as economic concentrations in ores that are three to six orders of magnitude larger than the Au mean content (∼0.001 ppm) of common crustal and mantle rocks (1 ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ –9).

The Mineralogy Of Gold And Its Relevance To Gold

Processing of most gold ores, other than placers, involves conventional gravity separation and direct cyanidation. The difficult (or refractory) gold ores are not amenable to direct cyanidation and these ores require detailed mineralogical investigations to assist in determining the recovery processes. There are six mineralogical factors that can contribute to poorer recoveries.
