Crushing. Once gold-rich ore is excavated, it needs to be crushed into a fine powder before it can be processed. The initial crushing is done by hand with makeshift hammers, almost exclusively by women. Ball mills- tumblers full of steel balls- complete the final stage of crushing, producing finely ground ore-powder.

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 ...
