Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

The plant design includes a crushing and grinding circuit, followed by gravity concentration. The gravity concentrate is processed in a CIL circuit and gold is recovered from the loaded carbon in a conventional elution - electrowinning plant with smelting of the gold to a Dore bullion.

Every gram of gold from the stones is indispensable to experience mining – crushing – grinding – sorting – smelting – casting, etc., from the perspective of mineral processing, the crushing is the first mineral beneficiation process step, and it is almost a preparatory section for any gold processing plant.
