uses of hard rock mill tailings

DEPARTMENT OF ENVIRONMENTAL QUALITY Environmental

Basin Mill is used for ore mined from small hard rock mining operations. The mill utilizes crushing, grinding, and froth floatation to produce a concentrate from ore. The process results in the generation of rock tailings. This technique, first used in Montana in 1911, is commonly used for the recovery and upgrading of sulfide ores.

The difference between waste rock and tailings Aquila

Aug 30, 2018· Waste rock is bedrock that has been mined and transported out of the pit but does not have metal concentrations of economic interest. Tailings are the finely ground residuals that remain after the mill process has removed the valuable metals from the ore.
