天然磷矿石由于伴生有不同种类和含量的脉石矿物,因而品位较低,无法满足肥料及化学品工业应用的要求,磷矿中的磷酸盐矿物需要通过选矿技术加以富集,浮选法是一种较为普遍且有效的分离手段,在硅质、钙质或硅钙质磷矿中都有所应用(Luo等,1999;Sis等,2003)。由于脉石矿物的物性及其与磷酸盐矿物间相互作用的
Natural rock phosphate rock phosphate minerals associated with different types and levels, and thus lower grade, can not meet the requirements of fertilizer and chemical industry applications, phosphate rock phosphate mineral need to be enriched by beneficiation technology, flotation Is a more common and effective means of separation that is useful in siliceous, calcareous or calciuous phosphate rock (Luo et al., 1999; Sis et al., 2003). Due to the physical properties of gangue minerals and their interaction with phosphate minerals
