我国有丰富的钨矿资源,但大多伴生有磷灰石、独居石和磷钇矿等含磷矿物,因此有些选矿产品中含磷很高,影响产品质量。所以,进行磷的物相分析,搞清楚钨矿各级产品中磷的存在状态,对改进选矿工艺,提高钨精矿的质量是很有意义的。在钨矿中进行磷的物相分析,尚未见文献报导。本文研究了钨选矿产品中磷灰石、独居石和磷钇矿的物相分析方法。一、磷灰石的选择溶出
China has a wealth of tungsten resources, but mostly associated with apatite, monazite and xenotime phosphate and other minerals, so some beneficiation products containing high phosphorus, affecting product quality. Therefore, the phase analysis of phosphorus to find out the presence of phosphorus in all levels of tungsten products, to improve the beneficiation process, improve the quality of tungsten concentrates is of great significance. Phase analysis of phosphorus in tungsten ore has not been reported in the literature. In this paper, the phase analysis of apatite, monazite and xenotime in tungsten concentrates has been studied. First, the choice of apatite dissolution
