Continuous flotation process for enrichment of fluorite

摘要

The proposed process is used in the industrial production of fluorite of acid quality through the flotation at ambient temperature of fluorspar minerals and the invention relates specifically to the use of carbon dioxide (CO2) as a modifier of pH in the stages of conditioning, and subsequent acid leaching of the cell concentrate in order to improve the normal metallurgical yield of the process and ensure the quality of the concentrate obtained.
