    Any complex ore can be tested with CLS-20 21 and 22. Each leach has different oxidizers and leaching components. One of these combinations may work better on your ore. They are not for concentrates. Concentrates should be tested with CLS-25 a gold leach. If you are interested in purchasing the formulas please contact us.

    The cyanide then enters the heap and leaches the gold. Gold loves cyanide. Once the leach solution dissolves the gold it continues percolating through the lower lifts until it reaches the liner located underneath the heap. Then it drains into a storage pond. Most economical heap leach mines achieve 70-80 recovery of gold and 30-50 of silver.
