  • Heap Leaching of Gold and Silver Ores ScienceDirect

    2016-1-1 · For cyanide heap leaches, lime is usually blended in with the ore as it is stacked to maintain a pH value above 10. For ores that generate acid slowly, limestone can be blended in with the ore. Caustic can be used but is normally not economic and can result in chemical reactions that plug the heap or are detrimental to the recovery process.
