Nine Gold Extraction Processes for Vein Type Gold Mines

2020-4-2  This gold extraction process is focused on the froth flotation process, which is suitable for mines with close co-existence between gold and sulfide and can only be recovered by smelting. It is also suitable for gold-bearing quartz vein mines with uneven coarse intercalation, which can obtain a higher gold recovery rate than the single froth flotation process.
