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.

Gold Processing Methods & Gold Ore Extraction. Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized
