摘　　要：为实现湿法磷酸净化萃余酸的资源化利用,将萃余酸应用于磷矿反浮选中。在模拟并采用现场反浮选工艺的条件下,研究单独使用萃余酸和与硫酸混用的浮选效果,二者均能获得良好的选矿指标,可节约硫酸用量,降低选矿成本,为萃余酸的高效利用提供了新思路。In order to realize the resource utilization of raffinate acid from wet-process phosphoric acid purification apparatus,raffinate acid is applied to the reverse flotation of phosphate rock.Under the condition of simulating and adopting the on site reverse flotation process,the flotation effects of using the raffinate acid alone and mixing it with sulfuric acid are studied,and both of them can obtain good beneficiation indexes.It can save the consumption of sulfuric acid and beneficiation cost,providing a new insight for the efficient utilization of raffinate acid.
