CRUSHING AND GRINDING FOLLOWED BY GRAVITY SEPARATION This method of gold recovery has been practised for over 4,000 years, and was the only method of separating gold from its natural environment until the late 19th century. Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that

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.
