磷矿浮选就是指采用浮选法筛选磷矿石，根据矿物质表面性质差别，接触磷矿石设备、磷矿粉碎机、浮选药剂，让促使其选择性的黏附于气泡表面，以此实现分选的目的。根据目前的磷矿浮选工艺使用情况来看，泡沫浮选法是较为常见的方法，但是仍然有提升工艺效率的空间。因此，综合考虑多种浮选工艺、药剂类型，通过工艺优化、药剂制度优化的方法提升浮选有效性，有效筛选精矿石，提高作业经济效益。本文分别从浮选工艺、药剂等两个角度入手，对其应用现状与优化措施进行深入探究。“,”phosphate rock flotation is to use flotation method to screen phosphate rock, according to the difference of mineral surface properties, contact phosphate rock equipment, phosphate rock crusher, flotation reagent, so as to make them selectively adhere to the bubble surface, so as to achieve the purpose of separation. According to the current phosphate flotation technology, froth flotation is a common method, but there is still room for improving process efficiency. Therefore, comprehensive consideration of a variety of flotation processes, reagent types, through process optimization, reagent system optimization method to improve the flotation effectiveness, effectively screen concentrate, improve the economic efficiency of the operation. In this paper, the application status and optimization measures of flotation technology and reagents are discussed.
