Enhancement of Gold Heap Leaching by Using a Reagent

Nov 11, 2020 A relatively low yield during precious metal recovery by heap leaching (50 to 80 %) is associated with a number of reasons, including the difficulty of selecting the optimal process parameters due to the wide range of gold grain sizes: ultra-dispersed (nano-range) — from 10 –9 to 10 –7 m, fine-dispersed (meso-range) — from 10 –6 to 10 –5 m, and coarse (micro-range) — 10 –4 m
