Abstract: | The paper introduces a huge invastigation on mining recovery , mineral processing recov-ery and comprehensive recovery in fluorite mines of China .Fluorite minerals occurs mainly as sim-ple fluorite, total output of ores is about 6213.2 kt.Large scale fluorite mines were accounting for 2 .29%in all in China , small scale fluorite mines were 84 .20%and production capacity was ac-counting for 63.80%.Ming recovery is 84.99%, processing recovery 85.61%, comprehensive re-covery 72.51%.also 45.38%tailings from mineral processing is reutilized . |
