Mine tailings, the waste material left over from processing ore, are essentially tons of crushed rock with zero percent organic matter. Deposited in ten-foot "lifts," they are extruded like a thick toothpaste that dries out, according to Ian Pepper, director of the W-Q-C. Thousands of these raised, barren piles dot the Southwest.

A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using required mineral processing solutions to liberate the valuable metals. The discarded tailings are then dewatered and dry stacked, and the water recycled within the plant or properly disposed back to nature.

Tailings is a bi-product of the processing of ore. When the ore is processed, the valuable minerals are separated leaving the fine-grained waste material known as tailings. The tailings are usually pumped from the thickeners through a slurry transportation pipeline and deposited at a dedicated tailings management/storage facility.
