| Abstract: | Fluorite, as a non-renewable resource, is an important nonmetal mineral, is the main raw material of commerical fluoride products and widely used in metallurgy, chemical, building materials, light industry, optical, sculpture, defense and other fields.With the growing applications of fluorite, the demands for fluorite are also increasing, therefore, more and more attention also has been paid to the development and use of fluorite ores.The mineral processing methods and the reagent system of quartz fluorite, calcite fluorite, barite fluorite and sulfide ore fluorite are reviewed, in order to improve the selectivity of the reagent, adopting automatic control and accurate dosing to control combination and dosage of the reagent is proposed; the flotation column is used to reduce concentration times and the process is simplified; used a combined mineral processing and chemical treatment to improve the quality of concentrate and so on are effective means of improve the efficiency of fluorite recovery, the future research direction and development trend of fluorite ore dressing are pointed out. |
