Here Is The Correct Way To Effectively Recognize Gold Ore

07-12-2018  The ore is usually brown, a metallic iron color, or mixed with a large white quartz rock that has very little gold in it. Gold is heavy and highly malleable. Gold will not change color, crumble, or tarnish, and is unaffected by most solvents. Gold is commonly alloyed with silver and other metals.

metal ores, the gold is floated from the base metal tailings. The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES

The fourth class of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type. They are often low in grade but large.

Gold extraction - Wikipedia

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.
