WeProcessBlackSands. Due to the heavy iron content of blacksands, most processors, smelters and refineries are unable toprocessthem. We have a unique chemistry that allows us to aggressivelyprocessprecious metals at 20 mesh and below in less than one hour, so we can effectively leach blacksandswithout dissolving the majority of their iron content.

The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than the melting point of gold. The impure gold is therefore melted and gaseous chlorine is blown into the resulting liquid.
