Tailings Disposal of Mining Metal Ores Industrial Minerals. Mining and oreprocessing methods are similar in the metalore and nonmetal mineral industries, as are waste disposal techniques. The wastes of interest are waste rock, overburden and oreprocessing wastes (or tailings).
The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
Jun 29, 2018· Tailings from the ore processing facility will be treated to reduce the cyanide levels and stabilize mercury, and would then be transported in a pipeline to the Tailings Storage Facility (TSF) built in the Anaconda Creek valley. The TSF will be constructed by building a tailings dam across the lower part of the valley.

The slime residue from the absorption section can be pumped either to the tailings dam or the backfill plant. Finally, the gold bearing carbon is removed from the absorption section and pumped to the elution circuit to remove the gold from the carbon. The gold in solution is plated out in the electrowinning circuit, where it is smelted.
