    Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off-site. (Some mines sort and dry sand on-site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process-water pond.

    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.
