 · Free-Milling Gold Low Grade In the case of low grade (< 1 g/t) free-milling gold deposits, the ore is often crushed and heap leached. While the recoveries are typically lower than what would be obtained with a conventional gravity-cyanidation flowsheet, the savings in CAPEX and grinding costs often justify this route. When clays or

 · Selective flotation tests were conducted to selectively prefloat a realgar-orpiment concentrate to reduce the arsenic in the concentrate for further gold recovery treatment. Firstly a stibnite concentrate and secondly a bulk sulfide (pyrite) concentrate were recovered. In the realgar-orpiment pre-float only frother was added.

 · 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.
