Gold processing 101
· 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.

Cyanidefree gold recovery
· Results indie it can be applied to a range of ore types. The Going for Gold process requires some additional 'offtheshelf' components and a new configuration, but is not complex and can be customised to deal with different ore types. It could allow small gold producers to mine lowgrade, uneconomic or stranded gold deposits, as well as gold reserves in jurisdictions where cyanideuse is ...
