Towards mine tailings valorization: Recovery of critical materials
Chile has a long history of mining and large-scale mining started in the first decade of the twentieth century. In 2016, Chilean mining exports were valued at 30,379 million USD according to the National Service of Geology and Mining (SERNAGEOMIN), 90% of which came from copper mining (SERNAGEOMIN, 2017).Chile is the world’s Since the mid-nineteenth century, gold ores, mainly hosted in sulfides, have been processed at metallurgical plants located in Nova Lima, Brazil.

Review of Practices in the Managements of Mineral Wastes
In 1999, tailings were economically reprocessed for residual gold recovery when the pressure-oxidation system was added to the processing plant circuit (Craw et al., 2017). In the context of the DR Congo mining industry, various ancient and recent studies related to the management of tailings demonstrate the possibility of For more than 30 years, sulfide gold ores were treated in metallurgic plants located in Nova Lima, Minas Gerais, Brazil, and accumulated in the Cocoruto tailings dam. Both flotation and leaching tailings from a deactivated circuit, as well as roasted and leaching tailings from an ongoing plant, were studied for their acid mine drainage Mineralogical and Geochemical Characterization of Gold Mining Tailings

Metals Free Full-Text Submarine Tailings in Chile—A Review
In Chile, tailings have been mainly produced by the copper and gold industries, and to a lesser, the iron and zinc industries . The government plan only covers 37 abandoned tailings, but according to Sernageomin (Spanish acronym of National Geological and Mining Survey), there are about 800 tailing deposits, mainly in the Antofagasta, Atacama, The process operated for 10 years (Tempel 2003; Roberto 2017) treating 800,000 tonnes per year of refractory gold ore and producing an estimated 500,000 oz of gold over 10 years.

Bioremediation techniques for the treatment of mine tailings: A
Mine tailings (MTs) are the materials dumped on a mining site after mineral extraction, containing scattered traces of residual minerals, dug-up soils, and a disturbed ecosystem. Abandoned and untreated MT can pose threats to the surrounding ecosystem due to the presence of various primary and secondary toxic components, study case for porphyry copper tailings, Chile reprocessing of tailings for recovery of metals like gold (Bugnosen, 2001), copper (EPA, 1993) or iron (Karlberg, 2010) is a 2014; Falagán et al., 2017).
