Gold extraction with mercury is an ancient method for gold separation. It refers to the chemical beneficiation method of wetting gold particles in ore slurry with liquid metal mercury to form an amalgam, so as to separate gold particles from other metal minerals and gangue This ancient gold extraction method has been gradually replaced by … Continue reading Anyone Else Use Amalgamation to Select Gold?

The average content of gold in the crust is 4×10-9. The industrial minerals of gold mainly include natural metals and intermetallic compounds, such as silver-gold ore (AgAu), gold-silver ore (AuAg) and so on. In nature, gold often coexists with pyrite, arsenopyrite, tetrahedrite, chalcopyrite, galena, sphalerite, and stibnite. Since more than 98% of gold in gold … Continue reading Gold Phase and Analytical Methods to Be Mastered in Gold Beneficiation

According to the different physical and chemical properties of rare earth minerals, associated gangue, and other minerals, the beneficiation of rare earth ore usually adopts the following methods.   1. Radiation Beneficiation Method It mainly uses the difference in thorium content between rare earth minerals and gangue minerals in the ore, and uses a γ-ray … Continue reading The Beneficiation Method of Rare Earth Minerals

Mineral processing methods are mainly divided into two categories, namely physical mineral processing and chemical mineral processing.   Physical Mineral Processing Physical beneficiation includes magnetic separation, gravity separation, electrostatic beneficiation, friction beneficiation, particle size beneficiation, shape beneficiation, corona beneficiation and manual beneficiation.   Chemical Mineral Processing Chemical mineral processing includes flotation method (physical and chemical mineral … Continue reading Guide of Mineral Processing Methods: 3 Main Beneficiation
