Quick figures: Morila gold mine’s reprocessing of tailings

Mar 12, 2021 In January, the mine produced 3,494 ounces of gold and 3,372 ounces of gold in February. The mine remains on track to meet guidance. It is intended to commence mining of satellite pits in mid-2021 and to enable processing of this ore, multiple capital works programmes are being undertaken at the processing plant and the tailings dam.

Causes and environmental impact of the gold-tailings dam

Nov 01, 2018 The Karamken storage pond (60°13′44″N, 151°04′22″E) was built in 1977 for tailings of waste pulp from the gold mining and mineral processing plant . The gold-extraction procedure included ore-crushing to a fraction of 0.078 mm with subsequent gold and silver chemical extraction using sodium cyanide at an average rate of 300 tons/yr.

Tailings dam Wikipedia

A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth. The Syncrude Mildred Lake Tailings Dyke in Alberta, Canada, is an embankment dam about 18 kilometres (11 mi) long and from 40
