以石英为主要伴生矿物的萤石矿,构造比较简单,一般用油酸类捕收剂即可有效浮选,获得萤石精矿。由于萤石精矿质量要求不同,在工艺上存在着颇大的差别。生产优质萤石精矿(CaF_2≥98%,SiO_2<0.5～0.8%)时,对选矿工艺有特殊要求。作者对此类型矿石,就降低萤石精矿中SiO_2含量的问题,进行了研究。一、磨矿工艺对萤石浮选的影响选择适宜的磨矿细度和磨矿流程是获得优质萤石精矿的前提。浙江东风萤石矿和湖北红安萤石矿的矿石浮选研究表明,以石英
Fluorite ore, with quartz as the main associated mineral, is relatively simple in structure and generally can be effectively flotated with oleic acid collectors to obtain fluorite concentrate. Due to the different quality requirements of fluorite concentrate, there are considerable differences in technology. Production of high-quality fluorite concentrate (CaF_2 ≥ 98%, SiO_2 <0.5 ~ 0.8%), the dressing process has special requirements. The author of this type of ore, to reduce the content of SiO 2 in fluorite concentrate was studied. First, the impact of grinding process on fluorite flotation Select the appropriate grinding fineness and grinding process is to obtain high-quality fluorite concentrate premise. Ore flotation studies of Zhejiang Dongfeng fluorite mine and Hubei Hongan fluorite mine show that the quartz
