Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation maintained.

The refractoriness of gold ores occurs by occlusion or entrapment of subatomic gold particles in matrices of sulfide minerals (pyrite, arsenopyrite, stibnite, etc.) and insoluble siliceous gangue, by association with tellurides, clays and carbonaceous matter [].The carbonaceous material can adsorb gold, an effect known as preg-robbing, from the solution similar to activated carbon, …

The simplest and most common association of tellurium with gold is as the mineral calaverite [AuTe 2], but other metal associations also occur.Silver associations give rise to the minerals petzite [Ag 3 AuTe 2], sylvanite [(Au,Ag)Te 2] and krennerite [(Au,Ag)Te 2].A gold-telluride association with antimony also occurs with the mineral montbrayite [(AuSb) 2 Te 3], …

After mining, silver-bearing ores are crushed, ground, and concentrated by flotation. Silver-bearing ore concentrate is subjected to specific processes depending on the major metal present in the concentrate. For copper ores, silver along with gold and platinum-group metals accumulates in the anode slimes during electrolytic refining of copper.

The origin of gold deposits has been the subject of considerable debate and remains controversial to this day. Most published ore deposit models in the literature to date involve gold being sourced from the mantle, the lower crust or the upper crust (Groves, 1993, Phillips and Powell, 2010, Thomas et al., 2011, Hronsky et al., 2012, Tomkins, 2013) transferred to …

Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.

It's universally considered the richest of the gold ores out there. The proper term for quartz that contains gold is auriferous quartz. The first word is just used in place of "gold-bearing" because of the need for specific words in the hard sciences like geology. Classically, you'll often find gold downstream from these formations.

The gold bearing solution from the leaching tanks is then pumped into a thickener where the gold bearing solution is thickened and the solids are allowed to settle at the bottom of the thickener. In this equipment, the solid particles are allowed to settle at the bottom thus making the density of the gold rich solution at the top to be higher.
