Abstract:Fluorite can be extracted to prepare fluorine and various fluorine compounds. It is a strategic nonmetallic mineral. As a nonmetallic mineral raw material, fluorite is widely used in industry. The overall reserves of fluorite resources are rich in China, but with poor resource endowment, low grade and complex properties, most of them are associated fluorite deposits. The main gangue minerals are quartz, barite, calcium carbonate and other minerals. Because gangue minerals have similar physical and chemical properties to fluorite ore, the flotation purification of fluorite is greatly disturbed and the separation is difficult. This paper summarizes the research progress in recent years on the basic theory, process flow and reagent system of flotation separation of associated fluorite ore, summarizes the problems and difficulties in the process, technology and reagent research of associated fluorite ore beneficiation, and introduces the development trend of associated fluorite ore beneficiation.
