Sep 07 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 extractionrecovery In the context of flowsheet selection the bashing and mashing stages are relatively straightforward.
Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.
