国内对低品位磷矿石的选别,一般都将矿石磨细,然后再进行浮选。虽要求的磨矿细度不是很细,浮选的矿浆温度和碱度也不是很高,但选矿比大,造成生产成本较高,又因矿石的全部细磨限制了对其它组分的综合回收利用,使矿山得利较少,所以本文将以青海上庄磷矿为例,阐明应根据矿石性质来选择合理的选矿方法,同时要综合考虑有用矿物的回收,以提高企业的经济效益这样一个观点。
Domestic selection of low-grade phosphate rock, the ore are generally fine, and then flotation. Although the required grinding fineness is not very fine, flotation temperature and alkalinity of the pulp is not very high, but beneficiation than large, resulting in higher production costs, and because of the fine grinding of the ore limits the synthesis of other components Therefore, this paper will take Qingzhuang Shangzhuang Phosphate Mine as an example to show that a reasonable beneficiation method should be selected according to the nature of the ore. At the same time, it is necessary to comprehensively consider the recovery of useful minerals in order to improve the economic benefits of the enterprise View.
