tailings are the product of processing ore to recover the contained metals. after extraction from the mine, the ore is crushed and subsequently ground to a
hydraulic mining, monitors, tailings, reworking of mine waste, tailings placement. a typical flow sheet for the reprocessing of tailings is shown below in figure 2. from the 60 million tonnes of tailings mined 695,000 ounces of gold was
mine tailings are generally disposed of by artisanal and small scale gold miners in indicating recovery of metals from the biomass through the smelt process.
mine tailings are formed as an industrial waste during coal and ore mining and processing. in the investigated process, following the extraction of gold from the
gold and platinum group and base metals from waste streams for 'ant heaps', old tailings which were processed. 100 years ago by gold mining companies.
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

the process to extract gold from mined ore produces waste called tailings, or slurry. at south deep, this slurry is made up of small mineral particles and water
in this process sediment or ore thought to contain gold is placed in a wide minerals fall to the bottom of the tank and are discarded as tailings.
tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. mine sites typically manage tailings by constructing ponds secured by dams. several efforts are underway to extract gold and copper from tailings. reprocessing mine tailings may also have environmental benefits.
