| 摘 要： | 为了优化洛阳燕子坡萤石矿的选矿工艺并提高选矿指标,进行了浮选试验研究。试验表明,品位为49.22%的萤石原矿在磨矿细度-0.074 mm占61%的条件下,采用碳酸钠为pH调整剂、水玻璃为抑制剂、油酸为捕收剂,经过"一次粗选、二次扫选、六次精选"的浮选试验,可以得到品位95.09%、回收率94.99%的萤石精矿。试验得出如下结论:1)随着碳酸钠用量的增加,萤石浮选所用油酸的量会减少;2)分段添加油酸为宜;3)分段刮泡有益。

| Abstract: | In order to optimize the beneficiation technology and improve the beneficiation indexes, the floation experiments were carried out. From the result, it was shown that a fluorite concentrate grading 95.09% and having a fluorite recovery of 94.99% can be obtained by flotation of one stage roughing two stage scavengings and six stage cleanings, using sodium carbonate as regulator, water glass as inhibitor and oleic acid as collector from the raw fluorite of grading 49.22% at a grinding finess of 61% -200 mesh. The conclusions were drawn that: 1.with the increase of dosage of sodium carbonate, the amount of oleic acid requisited in the flotation decreases by degrees; 2. a better beneficiation indexes can be obtained by using step-dosage method of feeding oleic acid; 3. step-dosage method of scraping foam is beneficial to the beneficiation indexes. |
