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.Guides For High-sulfide Gold Processing - cnlitereagent.comHigh sulfide gold ore refers to 20% -30% of gold wrapped by sulfide mainly pyrite . It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for high-sulfide gold ores.Ore Sorting Strategies In Mineral ProcessingBenefits Of Ore Sorting. Ore sorting can exploit a number of differences to sort particles including colour, density, hardness, radiation, and even electromagnetic properties. This means a wide range of mineral types can be separated using an ore sorting machine. Dense medium separation relies solely on particle density for sorting material ...

Oxide Minerals LLC

Oxide Minerals LLC. will be the managing partner in a 5 ton a day gold processing operation. Oxide Minerals is a leading edge technology company that has its own "Proprietary Method" of extracting Microscopic/Nano particles of gold from complex/refractory ores while using our "Patented Gold Separation Solution".Gold parting - WikipediaGold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.
