  • Precious Metal Heap Leach Design and Practice Ore Max

    Differential Recovery Is Not Sufficient To Justify Added Investment. A recent review (Kappes, 1998) concluded that for a "typical" Nevada type ore body with ore grade of 3.0 grams gold/tonne (0.088 oz/ton), the mill recovery would have to be 21% higher than the heap leach recovery to achieve the same return on investment.
