Tailings reprocessing technology means higher demands on mining enterprise, especially in tailings test, technological innovation, energy-saving and capital investment. For the majority of mining companies, they can't afford these huge capital investment and strict technical requirements.
Oct 15, 2019· With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing material.
DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013.

Today there are individual mines producing in excess of 200,000 tonnes of tailings per day. Understanding the mineral processing techniques can help to determine how tailings are produced and the challenges associated with their storage. Run of the mine ore is physically reduced by crushing and grinding methods (figure 2).
Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and ...
