mining method to extract hematite
Gold Extraction Methods From Three Types of Ore
The method relies on the difference in density between the gold particles and the surrounding rock. Water flow or centrifugal force can separate heavier gold particles from lighter material. Regardless of the method chosen to extract gold from quartz vein ore, it is important to ensure that sustainable mining practices are followed.
