胶磷矿的选矿试验研究,国内外大多采用浮选流程,主要有原矿直接浮选、反浮选、煅烧-消化等。也有进行光电选矿,重介质分选的报道。一般说来,采用直接浮选,磨矿细度都需在95％—200目以上,选别效果才好。本试验采用直接浮选进行探讨,在磨矿细度90％—0.08mm可获得较好指标。根据该矿含磷质条带与脉石条带存在比重差异,
Mineral phosphate rock phosphate dressing research, most of the flotation process at home and abroad, there are direct ore flotation, reverse flotation, calcination - digestion and so on. There are also reports of optoelectronic processing, heavy media sorting. In general, the use of direct flotation, grinding fineness needs to be above 95% -200 mesh, the sorting effect is good. The test using direct flotation to explore, in the grinding fineness of 90% -0.08mm get better indicators. According to the ore-bearing phosphorous belt and gangue belt there is the proportion of differences,
