摘　　要：对云南某碳酸盐型磷块岩矿进行了工艺矿物学研究,查明了矿石的矿物组成、结构构造、基本参数及主要矿物的特征。矿石中主要脉石矿物为白云石,通过单一反浮选脱除白云石即可获得合格磷精矿,有用矿物胶磷矿呈凝胶状、鲕状、假鲕状结构,嵌布粒度细,需要较大的磨矿细度才能使胶磷矿和脉石矿物解离。Study conducted on process mineralogy of the car- bonate type phosphate rock in Yunnan ascertained the ore mineral composition, structure, basic parameters and characteristics of main minerals. The major gangue mineral in the ore is dolomite. Desirable phosphate concentrate can be obtained by the single re- verse flotation process to remove dolomite. The useful mineral of collophane is of gel, oolitic, false oolitic textures in finely dissem- inated size, requiring greater grinding fineness to make collo- phane and gangue minerals be dissolved.
