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 mill

Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are 3.23 and 3.08, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.

Many hard rock discoveries brought a diverse array of people into some of the most remote yet breathtaking landscapes which normally wouldn''t be inhabited. Now outdoorsy folk spend countless weekends in towns like Lake City CO, hiking 14ers, fly fishing, backcountry skiing, or prospecting mining history from the locals in still standing false front saloons.

Waste materials used as backfill material include waste development rock, deslimed and whole mill tailings, quarried and crushed aggregate, and metallurgical process tailings (like slag) , , . Small amounts of cement or other pozzolanic binders are added to the waste material to improve the strength properties of the backfilled areas.

Uranium mill tailings also contain heavy metals, such as lead and arsenic. Large mounds of uranium mill tailings have been left at many old mining sites, and so remain a potential radiological and toxic metal hazard mainly due to the solubilization of 226 Ra, As, and Pb from ore minerals.

The gold milling process consisted of three general steps: (1) Sorting the ore by size. (2) Crushing the rock. (3) Extracting the gold. The rock fragments were sorted according to size in a grizzly, which was device consisting of a series of spaced bars, rails, or pipes, above a forward moving conveyer belt to a crusher machine.
