Some silver/gold ores are enriched in manganese and iron which are known to tie up the silver and reduce silver recoveries when using cyanide as a leaching agent. Rock Kleen has demonstrated an ability to recover manganese and separate the iron to release the silver that is tied up by the manganese and iron, making the silver recoverable.
In traditional cyanide leaching, ore is placed in vats or columns. The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery.
