    How to Identify a Gold Bearing Area Sciencing

    Gold prospecting and identifying goldbearing areas have become increasingly more feasible due to research developments on the geological process of gold formation. See References 1. Gold bearing areas mostly throughout the western United States have drawn and sprouted entire communities based on prospecting..

    The zinc precipitates contained 14.40 pct Au and 0.35 pct Ag. The preciousmetalbearing steel wool cathodes contained 20.65 pct Au and 4.84 pct Ag. The precipitates and cathodes were treated with dilute acid to solubilize the silver andor base metals. The goldbearing residue was leached in dilute aqua regia to solubilize the gold. High.

    US4188208A Recovery of gold from carbonaceous gold

    When certain sedimentary gold ores containing indigenous organic carbonaceous materials are slurried with an aqueous solution containing an alkali metal cyanide the aurocyanide complex which is formed is adsorbed by an adsorptive carbon component of the ore. Dissolution of the gold proceeds until chemical equilibrium is attained between the aurocyanide complex in solution and the aurocyanide.

    We Process Black Sands. Due to the heavy iron content of black sands most processors smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour so we can effectively leach black sands without dissolving the majority of their iron content.

    Hard Rock Mining Gold and Silver Ore and processing it

    The first step in pocket hunting is to identify a gold bearing area that may have pockets usually a smaller drainage in an area known to have produced coarse gold in the past. The goal is to find a drainage with a single gold source or at least one dominant source that is contributing the majority of the gold too many different sources.

    The extracted ore must be mill ed to prepare it for further recovery activities. Uniformly sized particles may be obtained by crushing grinding and wet or dry classification. The degree of milling performed on the ore depends on the gold concentration of the ore mineralogy and hardness of the ore the mills capacity and the next planned.

    Removing the goldbearing rock from the ground is just the first step. To isolate pure gold mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel.

    Sulfide ores and pyrites in particular have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances visible gold can not be seen under microscopic examination of pyrite gold ores. However if the ore is ground to 200 mesh most times a few specs of gold can be visibly seen under microscopic.
