Superior Silica Sands will have the capacity of billion pounds of sand production in 2014. Although this is a large number in the industry, we feel with our superior service and quality this will catapult us to the thirdlargest frac sand supplier in North America.
Silica sand deposits are most commonly surfacemined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.
Even after final processing, you will still find that you concentrates, which are now "super concentrates", will still have a mix of fine gold and fine black sand particles. Here is where the magnetic nature of black sands will help us in the final separation process. Using a rare earth magnet, we can physically pull them away from the gold.
