· According to the company, thanks to advances in separating, sorting, and crushing equipment, very small diamonds can be recovered from the residue of the original diamond-bearing ore. De Beers recovered 815,036 carats of diamonds from 6,133,799 tons of tailings in 2013 and expects to continue operations beyond 2030.
Gold recovery rate of the chute, jigging and shaker is not high, the yield is very low (generally not more than 0.5%), and the strength is uneven, fine-grained minerals are difficult to be recycled, and the jigs have slight lost in the process. In addition, since the coarse-fine grain gold is not well recovered in the re-election stage, the ...
Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, …
