摘要
矿石目的矿物萤石与细粒隐晶质石英关系极为密切,石英含量高,达50%以上,且呈极细粒状产出在萤石中,另外还含有泥状矿物(高岭土),提高萤石品位,降低精矿中硅含难度较大。经试验研究,获得试验指标如下:萤石原矿品位45.11%,精矿品位CaF297.23%,萤石回收率55.18%。
The relationship of aim mineral in ores fluorite and crypto-crystal quartz is very close ,the content of quartz is high,over 50%,its partical very fine,and there are some mud minerals in the ores.Improving the grade of fluorite is very difficult.By experimental research,the results of concentrate grade of sluorite 97.23% and recovery of sluorite 55.18% are obtained.
