摘要:
报道了3种不同类型中低品位磷块岩在磨矿过程中成分发生分异的基本特征,并对其机理进行了探讨.在磨矿过程中,细粒级磷块岩粉体趋于贫化,胶磷矿含量降低、脉石矿物含量增加.层状铝硅酸盐矿物在硅质及硅钙质磷块岩细粒级粉体中明显富集,对矿石的浮选将产生不利影响.磷块岩在磨矿过程中成分发生分异的程度取决于矿物的工艺性质,包括硬度、嵌镶关系、嵌布粒度以及解离性等.
Abstract:
This paper reported some component differentiation features of three types of midlow grade phosphate rocks in grinding. The related mechanisms were discussed. By grinding,the finer phosphate rock powders tended to be impoverishment, for the decrease of collophane and the increase of gangue minerals. Phylloaluminosilicate minerals obviously concentrated in fine powders of siliceous and siliceous calcareous phosphate rocks, which is unfavorable to the flotation of the ores. The differentiation degree of minerals depends on their process properties, including hardness, grain size, intergrowth patterns and liberation properties.
