Abstract
A method for reducing the turbidity of as-mined sand comprising adding water to the as-mined sand to increase its moisture content to between about 5% and about 40% by weight, mixing the sand and water, piling the wet sand on the ground, allowing the sand to rest for a predetermined period of between about 12 hours and about 3 days, then harvesting less than all of the sand from the pile as reduced turbidity sand.
