Black Sands Processing « TCB Metals and Refining

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. Due to this innovative leach, TCB can effectively process precious metal bearing black sands
