Gold processing 101 - Mining Magazine

07/09/2017  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. However, there are a number of other considerations when it comes to the

01/02/2014  As the quality of gold deposits continues to decrease, it is expected that processes which can economically extract gold from low grade ores will grow in importance to the minerals industry. Biotechnology has the potential to transform uneconomic gold reserves into resources. Bioprocessing can be attractive for: 1) low grade gold ores that are too expensive to process using conventional processes and 2) ores that contain impurities that foul conventional processing

Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. The prospector’s gold pan is the most familiar gravity concentration device. To function properly, the ore must be broken down to particles small
