3.1.1. Gold and silver beneficiation. The content of gold in the ore was very low. In order to extract gold, it was necessary to crush and grind the ore and preconcentrate or separate gold from the ore by mineral processing. Flotation and gravity separation were widely used in gold processing. Gravity separation played an important role inWeb
