Tailings ponds are used to store the waste made from separating minerals from rocks, or the slurry produced from tar sands mining. Tailings are sometimes mixed with other materials such as bentonite to form a thicker slurry that slows the release of impacted water to the environment.


Mar 05, 2019· 1. Introduction. Currently, Chile is one of the World’s most important copper producers [], and due to this activity, large quantities of residues have been accumulated, where mine tailings are considered as being among the most relevant [].These fine-grained residues, generated during mineral concentration, contain considerable amounts of metals such as manganese, zinc, and others [3,4 ...


The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world's total copper mine capacity. Chile and Peru, alone, account for about half of the copper mines on this list, but the U.S. does make the cut, with two mines among the top 20.
