摘要
河北某萤石矿含CaF2为30.95%,属于低贫萤石矿,在一段磨矿细度为-200目65%,二段磨矿细度为-400目100%时,通过1次粗选、6次精选的浮选工艺,获得了含CaF298.50%,回收率为54.10%的萤石精矿。
The grade of the low quality fluorite ore in Hebei was assayed around 30.95% CaF2.When the grain size achieved by 65% of -200 mesh at the first stage grindings and the grain size achieved by 100% of -400 mesh at the second stage grindings,the circuit of one rough floatation and six cleaning floatations were used in the recovery of fluorspar,the result was obtained that the fluorite concentrate grade of CaF2 was 98.50%,with the recovery of 54.10%.
