Gold extraction

Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction. Gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. In modern practice, concentrators use centrifugal force in order to liberate finer gold particles.
