Gold Ore
Extraction methods for gold ores depend on the type of ore, its grade, and other factors such as the presence of other minerals and impurities. Here are some of the most common extraction methods used for gold ores: 1. Gravity separation. This method is used for free-milling gold ores and involves using gravity to separate gold from other minerals.
