随着社会主义建设事业的迅猛发展,国家对于磷矿的需要量也日益增加。我国磷矿资源相当丰富,但大多属于难选的中低品位的磷块岩。因此,研究这类中低品位磷块岩的选矿富集方法,已是当务之急。 为了响应毛主席“开发矿业”的伟大号召,适应当前大打矿山之仗,开发利用中低品位磷块岩的需要,我们以解决湖北荆襄硅—钙质磷块岩浮选的技术难关为目标,相应地开展了浮选药剂的研究工作。我院曾用普通浮选介质对中低品位磷块岩做过多次浮选试验,都没有 With the rapid development of socialist construction, the demand of the country for phosphate rock is also on the rise. China’s phosphate rock resources are quite rich, but most of them are refractory low-grade phosphorite rock. Therefore, the study of such low-grade phosphate rock beneficiation enrichment method, it is imperative. In order to respond to the great call of Chairman Mao for “mining development” and to adapt to the current battle of mines and to develop and utilize low- and middle-grade phosphorite, the technical difficulties of flotation for Jingxian-calcareous phosphorous rock in Hubei Province are: The goal, the corresponding research carried out flotation reagents. Our hospital has used ordinary flotation medium on the low-grade phosphate rocks have done many flotation tests, none
