Feb 01, 2009· The bioleaching of iron oxides by Aspergillus niger resulted in removal of 47. 70% of the total iron in the quartz sand, and suggested that this strain has not a good ability to remove iron impurities from quartz sand in comparison with chemical leaching. The iron content decreased from 0.315% Fe2O3 to 0.164% Fe2O3 in the bioleached quartz sand.
This process utilizes magnetic and float separation to remove impurities. After the sand has been washed and dried and contaminants have been removed, it is screened. In this process, sand is separated according to grain size and stockpiled for future blending. These numerous demands for sand require mining of our dunes and other sand resources.

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.
