对两种主要类型的难选多金属萤石矿的萤石选别进行了分析研究。发现调整合理的浮选矿浆ｐ Ｈ 值对提高萤石精矿质量很重要。另外流程结构及矿浆中重金属离子含量对萤石精矿品位也影响较大。
Fluorite classification of the two main types of refractory polymetallic fluorite has been analyzed. It was found that adjusting the p H value of a flotation slurry with reasonable fines is very important for improving the quality of fluorite concentrate. In addition, the flow structure and the content of heavy metal ions in the pulp also have a great influence on the grade of fluorite concentrate.
