Black Sands Processing « TCB Metals and RefiningWe 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.

Gold Mining: How Do We Get Gold Out of the GroundThe simplest method of placer mining is panning. Here the miner swirls the mixture in a pan rapidly enough to carry the water and most of the gravel and sand over the edge while the gold remains on bottom. This was the classic method used by the FortyNiners during the California gold rush of 1849 and has been immortalized in story, art, and song.
