Title
The fuction of aliphatic Acids on Soap Flotation of Fluorite
최형섭 Hyung Sup Choi
Abstract
Results of the tests led to the following conclusions: (1) The optimum pH, at 25℃, ranges from 8 to 10 in soap flotation of the fluorite ore. (2) Fatty acids with higher iodine value than about 180 are powerful and selective collectors for fluorite flotation. (3) The highly unsaturated fractions of fish oil fatty acids are very effective collectors for fluorite. (4) Those acids having iodine values lower than about 180 are unsatisfactory for floating fluorite at 25℃, but both grade and recovery of concentrates are improved markedly at elevated temperature. (5) The effect of temperature on grade of concentrate was not marked with the highly unsaturated fatty acids, but fluorite recovery with these acids exhibited a very slight increase with increasing pulp temperature.
