黄梅磷矿属细粒嵌布的磷灰岩矿床。矿石磨至-200目占78％进行浮选。由于矿石风化严重,在碎磨过程中容易过粉碎,生成大量微细粒,严重影响浓缩过程。尤其因为浮选采用了脂肪酸类捕收剂,精矿泡沫发粘难碎,致使浓缩池中的泡沫层过厚,底流浓度难以达到过滤要求,而溢流中有用矿物又大量流 Huang Mei Phosphate is a fine-grained apatite deposit. Ore mill to -200 mesh accounted for 78% flotation. Due to the severe weathering of ores, it is easy to crush during the crushing process to produce a large amount of fine particles, which seriously affects the concentration process. Especially because flotation using fatty acid collectors, sticky refractory concentrate foam, resulting in thickening foam layer is too thick, underflow concentration is difficult to meet the filtration requirements, and the overflow of useful minerals and a large number of streams
