河南中低品位铝土矿选精矿溶出性能工艺研究
Study of the digestion performances of lower-medium grade bauxite in Henan
【摘要】 通过对河南铝土矿选精矿进行溶出试验,在配料αk为1.5的条件下,重点对溶出过程的影响因素:CaO添加量、溶出温度、溶出时间、母液Nk浓度进行研究。找出了河南铝土矿选精矿的最佳溶出条件和范围。
【Abstract】 Digestion test was made on the bauxite concentrate,focuses of which are addition amount of CaO,temperature,time and Nk concentration in case that αk is 1.5,getting the optimum digestion condition and scope of bauxtire concentrate.
