  • Heap Leaching Agglomeration

    Recoveries by agglomeration heap leaching range from 70 to 90 pct, and depend on the ore being processed. Conventional heap leaching was used before the agglomerating equipment was on line. Gold recoveries were less than 50 pct because of fines migration and the high clay content, which caused blinding and channeling of leaching solution.
