Gold Extraction from Different Types of Ore

Jan 10, 2020  Flotation gold extraction process is mostly used for polymetallic ore. Generally, gold is enriched in non-ferrous metal ores and then comprehensively extracted through smelting. But for gold-bearing pyrite, it needs to be recovered by cyanidation after flotation extraction process. 12.
