Diagnostic Leaching For Refractory Gold Ores | SRK ConsultingStage 1: Gravity concentration to remove the gravity recoverable gold from the sample, followed by cyanidation of the tailing to determine the cyanide leachable gold. Typically, a sample is ground and then subjected to gravity concentration with a centrifugal gravity concentrator, followed by handpanning, or on a Mozleytype table.
