Fluorite Recovery from Ores Tailing by Using Flotation Technique
The purpose of this study is to recover fluorite from ores tailing which derived from fluorite processing plant in Thailand. Flotation technique was undertaken to improve the concentration. Oleic acid, Methyl Isobutyl Carbinol (MIBC) and sodium silicate were optimized. pH condition was also carried out to find the best condition. The experimental results show that the effective performance when Oleic acid and sodium silicate were utilized at 800g/t and 500g/t respectively. Weak alkaline condition at pH 9 indicated the best effective condition. Therefore, the optimal condition could probably recover fluorite from ores tailing which is great for fluorite flotation in order to raise economic profits.
