Marine and Riverine Discharges of Mine Tailings

2020-11-5  Mine tailings are what is left over from the mined ore after the target metal (e.g., copper or gold) has been separated from the ore. Separation is achieved by an industrial process using physical grinding and crushing to break the ore into small particles followed by chemical extraction and flotation methods. Mine tailings are known to contain ...

From Tailings to Treasure? Miners Make Money

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 US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings

What are tailings dams? IndustriALL

What are mine tailings? Tailings are the waste products from mining. Mechanical and chemical processes are used to grind up rock into a fine sand to extract the valuable mineral or metal from the rock ore. All the unrecoverable and uneconomic remnants from this process are waste. They include finely ground rock particles, chemicals, minerals ...

Geoenvironmental Characterization of Sulfide Mine

The mine tailings were produced from grinding and metallurgical treatment of mineral from Eloy and Brunite mines between 1952 and 1981 . The main ore minerals are pyrite, sphalerite, galena, marcasite, and pyrrhotite. Other minor sulfides include arsenopyrite, minerals of the tetrahedrite-tennantite group, chalcopyrite, and stannite .

2020-10-28  Tailings are usually produced at some mineral processing and mine sits. In the mining, the most part of the mines are tailings whereas the extracted minerals are just small part of all fractions. After low-grade ores has been utilized, almost 99% of main materials may finally become tailing. Therefore, tailings contain large part of waste in mining
