Heap leaching consists of stacking crushed or run-of-mine ore on impermeable pads, where a weak cyanide solution is applied to the surface of the heap to dissolve the gold. In both cases, the gold-bearing solution is then collected and pumped to process facilities to remove the gold by collection on carbon or by zinc precipitation.

Metals 2015, 5 1310 240 min. However, the intensity of the Fe peak decreased with increasing the grinding time, since Fe remained after 240 min grinding and Fe could be dissolved by acetic acid leaching; therefore, it is difficult to expect selective leaching of Nd.

2020/10/21This process enables us to extract Li from lepidolite via a water leaching treatment. Mixed grinding with Na2S followed by water leaching was performed to extract Li from lepidolite. The leachability of Li increases dramatically in the ground mixture, regardless of the mixing ratio over the range of 1:1 to 3:1, while only 4.53% of Li was extracted in lepidolite ground without Na2S.
