Gold Extraction Recovery Processes
2021-5-8 Cyanide acts too slowly on coarse gold, but readily dissolves fine gold. Flotation concentration is not effective on coarse gold. The small miners who wish to treat a small tonnage of high grade ore and want a quick return rather than for recoveries near to 100%, probably still find the amalgamation process the best available recovery method.
