Hard Rock Gold Processing
The hard rock gold mining process enables the extraction of valuable gold from rocks and ores, mainly including crushing, grinding and gravity separation to form gold processing plants. The plant is large processing capacity, low operating cost, and can recover even fine gold particles efficiently. Crushing: In the crushing stage, there are ...

Gold Milling and Concentration
After washing with water and drying, the gold could be melted and cast into bars. Although the process captured 90 percent of the gold, mills quickly abandoned the process because of the expensive reagents, inefficient and clumsy process and deadly chlorine gas. German scientists discovered cyanide's ability to dissolve gold in 1846.
