Popular Beneficiation Methods For Extracting Gold From Minerals
The content of gold in minerals is relatively low. In order to extract gold, it is usually necessary to crush and grind the ore, and then use mineral processing methods to pre-enrich or separate the gold from the ore.However, there are many types of gold ores, such as placer gold, rock gold, associated gold, polymetallic sulfide gold, telluride gold ore, etc. Gold ore has a high …
