Beach Construction – Water Quality Impacts of Dumping Sand

of sand to a lake or shoreline, where it can erode into the lake, accelerates the process. If a shoreline does not have a natural beach, a constructed beach will probably not remain without sand added over time. The dumped sand will either drift away with shoreline currents or slowly settle through the soft, mucky bottom sediment.

Black Sands Processing « TCB Metals and Refining

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.
