我国磷矿资源丰富，但富矿少，贫矿多。目前富集方法主要是浮选、擦洗脱泥等工艺，难以有效分离磷酸盐与碳酸盐，而开发磁罩盖法可为磷矿的处理技术提供一种崭新的途径，具有广阔的发展前景。早在１９８４年，英国就提出了选择性磁罩盖法分离磷灰石，成功地分离了人工混合... Phosphate rich in resources in our country, but less rich, lean ore and more. At present, the enrichment methods are mainly flotation, scrubbing and desliming techniques, which make it difficult to separate phosphate and carbonate effectively. The development of magnetic capping method can provide a new approach for the treatment of phosphate rock and has broad prospects for development . As early as 1984, the UK proposed a selective magnetic capping method to separate apatite and succeeded in separating the artificial ...
