Diagnostic Leaching Gold Ores Scissor Grinding Quality

Refractory Gold. Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are: • Physical encapsulation – Extremely fine ( 10 m) particles are locked within an impervious, unreactive mineral.
We have 40 years of experience in mechanical manufacturing and provide you with the most sophisticated equipments.

Ores can often respond to gravity and/or magnetic separation. However, due to the presence of lower-iron content, iron minerals such as goethite, mass yields and recoveries to high grade concentrates can be low. Trade-offs are then required between recovery and product quality (iron grade and penalty element content).

Diagnostic Leaching For Refractory Gold Ores

Diagnostic Leaching For Refractory Gold Ores

A typical 5-Stage diagnostic leach procedure includes: Stage 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 hand-panning, or on a Mozley-type table.
