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.

The gold bearing sands along the Pacific Ocean beaches are heavily made up of black sands. These are heavier iron minerals that weigh more that normal sand, and they will overload your gear if you feed it too quickly. Instead, feed sand into your equipment at a measured, even pace that gives the sand proper time to sort over the riffles.

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
