Waste Mine Tailings Characterisation For example, during the period 1960 1977, approximately 96 percent of all copper ore production was centered in just five states, four of which are located in the southwest Arizona 54 percent, Utah 19 percent, Montana 10 percent, New Mexico 7 percent, and Nevada 6 percent

Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for every ton of ore Tailings containment facilities are regarded as the world's largest man made objects Terminology Mine tailings' size and composition depends on the mining method

Production commenced in 2008 and the first copper cathode was produced in Q4 of the same year In 2014 mining operations from the open pit ceased However, residual copper production continued utilising surface and sub surface leaching using injection wells

production at this time was only around 1,000 tpa Subsequently cobalt arsenic deposits were also mined in Bou Azzer, Morocco from 1932 and the Blackbird district of Idaho, USA from 1952 From around 1926, cobalt production as a by product from the Congos copper mines
