Abstract: The CaF2 grade of a quartz type fluorite is 44.38%.In order to develop and utilize the resource efficiently,research on the mineral processing technology was carried out.The results show that:under the conditions of grinding fineness of -0.074 mm 54%,oleic acid dosage of 1.5 kg/t,sodium carbonate of 600 g/t,sodium silicate of 400 g/t,flotation temperature of 30 ℃,stirring and pulp mixing time of 7 min,the closedcircuit flotation process of one roughing,five lceaning and one scavenging finally,highquality fluorite concentrate with CaF2 grade of 97.15% and recovery of 90.36% can be obtained.
