Once the gold ore is extracted, it undergoes further processing to separate the valuable gold from the impurities. This typically involves crushing the ore into smaller fragments and then grinding it into a fine powder.
Stage 3: hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation …
