Historic Gold Mine Tailings FAQ What are gold mine tailings? Tailings are a byproduct of a gold mining process that was common in the late 1800s and early 1900s. Goldbearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold.
DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US40 million, in .
Root symbionts a tool for remediation of gold mine tailings. An evaluation of rhizobial and mycorrhizal inoculum potentials and of physicochemical properties of materials with different degradation levels (tailings, waste rock, two sites reclaimed in 2009 and a natural site outside the mine) was carried out on Essakanes mine.
Tailings from gold mining operations can pose a threat to the environment and health of nearby communities. Not only can this waste be harmful if it leaches into groundwater, but it can also mean ...
Barrick Gold Corporation has one of the largest openpit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world''s deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground.

Inferior extraction techniques, combined with plenty of available high ore grade resources have historically made processing lower grade ores and tailings uneconomical and a low priority. However, as high ore grades become extinct and technology around extraction improves, tailings are becoming an increasingly attractive resource.
Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.
