Gold Heap Leaching Process Technical Requirements
网页2021-6-25 01 Granulation. To make the gold heap leaching process successful, the heap leaching material must have good permeability so that the cyanide solution can evenly pass through the ore pile. Most ores need to be crushed to 25.4mm or finer before granulation in order to expose the gold contained in the ore and improve the gold recovery rate.
