Ore Dressing Methods

Gold Ore ProcessingMethods of Ore TreatmentAmalgamationConcentrationCyanidationGold-Milling DataThe fact that a product of high value and small bulk can be produced at a gold mine, often by relatively simple milling processes, has made it possible to operate gold mines successfully in remote and inhospitable regions where high costs of transportation, fuel, and power would make it impossible to exploit profitably base-metal ores of equal dollar value. As a result, in many instances gold-mine development has been the advance guard of civilization in regions where other mineral resources were
