Gold processing 101 - Mining Magazine

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