  • particle size for gold leaching cyanidation

    7.1.2.5 Cyanidation Leaching Currently, cyanide leaching is the chief method use. In this technique, sodium or potassium cyanide solution is either applied directly to ore on open heaps or is mixed with a fine ore slurry in tanks. Heap leaching is generally used to recover gold from low grade ore, while tank leaching is used for higher grade ore.
