锦屏磷矿为沉积变质磷块岩矿床。浮选使用S_(808)和磺化酚焦油甲醛缩合物,不能达到预期的效果;用木素磺酸钙以提高磷精矿的质量,特别是降低磷精矿中MgO含量,其作用也不大。但使用腐植酸系列产品F_(103),可降低精矿中MgO含量,并使尾矿水COD指标也有所降低。实验室通过一粗一扫二次精选的闭路试验,可以得到P_2O_530.45％、回
Jinping phosphate deposit is a metamorphic phosphorite rock deposit. Flotation using S_ (808) and sulfonated phenol formaldehyde condensate, can not achieve the desired results; calcium lignosulfonate to improve the quality of phosphate concentrate, in particular, to reduce the content of MgO phosphate concentrate, and its role is not Big. However, the use of humic acid series F_ (103), can reduce the content of MgO concentrate, and the tailings COD index also decreased. The laboratory through a thick sweep of the second selection of closed-circuit test, you can get P_2O_530.45%, back
