摘要:
胶磷矿浮选过程选择性差的根本原因,是由于矿物组分尤其镁离子的溶解,造成矿物表面性质相互转化和捕收剂皂盐在矿物表面无选择性沉积. 通过控制浮选条件和药剂制度,尽可能避免捕收剂和溶解组份在矿物表面无选择性吸附或沉积,是选择性调控胶磷矿浮选性质的重要手段. 此外,采用机柱联合浮选装置来改善胶磷矿的浮选分离环境,对提高其浮选效率也非常重要. 实验表明:对原矿含五氧化二磷22.16%、氧化镁3.15%、二氧化硅25.41%的湖北远安磷矿石,通过采取以上改进措施,采用简单的单一浮选工艺,可获得磷精矿五氧化二磷品位>30%、回收率>80%和氧化镁品位1%左右的分选指标
Abstract:
The dissolution of mineral components, especially magnesium ions, in the process of collophane flotation produces surface conversion and non-selective deposition of collector soap on the surface of minerals, which causes a poor-selectivity. Regulating flotation condition and reagent system to avoid the non-selective adsorption or deposition of collector and dissolved components on surface of minerals is an important way to selectively control the flotation performance of phosphate. Additionally, using flotation device developed by combining flotation machine and column to improve the flotation separation environment is also an effective way to increase the flotation efficiency. The final separation results with phosphate concentrate grade of more than 30%, recovery of more than 80% and magnesium oxide grade around 1% can be obtained for Yuan’an phosphate ore in Hubei Province, which contains-phosphorus-pentoxide of 22.16%, magnesium oxide of 3.15%, and silicon-dioxide of 25.41%, by taking the above improvement measures and using a simple single flotation process technology.
