Sand used in the petroleum industry has been produced in Wisconsin for over 40 years. In recent years, however, the demand for industrial sand has increased exponentially. This growth in industrial sand mining can be attributed to the oil and gas extraction technique known as hydraulic fracturing which relies on silica sand.

Sand Washing and Desliming. Silica sand pumped from the pit is passed over a screen, either stationary, revolving or vibrating type, to remove tramp oversize. The screen undersize is washed and dewatered generally in a spiral type classifier. Sometimes cone, centrifugal and rake type classifiers may also be used for this service.

The remainder is mostly silica sand (up to 60%), fine solids (less than 30%) and no more than 5% water. As the ore is processed through the Bitumen Production facility, large volumes of process water are added to produce a slurry that can be gravity separated, recovering the bitumen and leaving behind coarse sand, fines and process water.
