GOLD RECOVERY The golden age min-eng.com

refractory gold ores are sulphidic in nature. This means that flotation is invariably the first process option to consider. This is relatively straight forward and achieves high gold recovery. The higher the gold to sulphur ratio the better in terms of downstream processing options. For refractory gold ores gravity recovery is usually poor and

low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad. A sprinkler system provides a continuous spray of alkaline cyanide solution that percolates through the ore dissolving the gold. The gold bearing or pregnant solution is collected and pumped to a gold recovery plant.
