Gold Tailings Reprocessing Technology

In general, Xinhai extracts gold from old tailings by all-slime cyanidation and CIL technology. The gold tailings after cyanidation are dealt with tailings dry stacking method. It is a technology that recycles the filtrate to realize the water resources recycling in processing plants with pressure filtration process, and get rid of most cyanide in the tailings. For other elements in the gold tailings, Xinhai applies

Tailings. As the ore gets processed and the valuable minerals gets separated, a fine-grained mineral sand remains as waste, called tailings. The amount of tailings that remain is controlled by what grade the ore is, meaning the percentage of valuable minerals in the ore. For example, if the grade of an ore is 1 percent copper, 99 percent of the ...
