含CaF_2平均不低于27—30％、矿石储量具有经济效益的萤石矿床都应认为是工业矿床。无论是单一的萤石矿体,还是除萤石具有实际意义外,还含有钽、铌、稀土、铅、铜、磷及其它元素的综合性矿体,都应符合这种要求。目前将萤石原料划分为两种主要的矿石建造:萤石建造和含萤石的碳酸岩建造(表1)。 An average of not less than 27-30% CaF 2, fluorite deposit with ore reserves economically benefits should be regarded as an industrial deposit. Whether it be a single fluorite orebody or a synthetic orebody containing tantalum, niobium, rare earth, lead, copper, phosphorus and other elements in addition to the real meaning of fluorite, this requirement should be met. Fluorite materials are currently divided into two main types of ore construction: fluorite construction and fluorite-containing carbonate construction (Table 1).
