新型植物胶类沉降剂对胶磷矿的沉降性能

Settling performance of novel plant gum settling agent on colloidal phosphate ore

磷矿是国家重要的战略资源,我国大部分的磷矿石都是中低品位胶磷矿,这种磷矿对磨矿有很高的要求,合适的磨矿粒度是其单体解离的必要条件,但磨矿细度的降低导致其精矿和尾矿沉降困难,开发特效沉降剂提升沉降效率具有重要意义。以典型胶磷矿为研究对象,利用所开发的新型植物胶类沉降剂,同时实现精矿和尾矿的高效沉降,探究了其最佳使用条件,并通过工业试验验证了其良好的应用效果,未来可广泛应用于胶磷矿选矿产生的精矿和尾矿的沉降。

Phosphate ore is an important strategic resource of our country,most of them are middle and low grade colloidal phosphate ore.This kind of phosphate ore resource has high requirements for grinding,and appropriate grinding fineness is the necessary condition for monomer dissociation.However,the reduction in fineness of ore grinding makes it difficult to settle the concentrate and tailings,and it is of great significance to develop special settling agents to improve the settlement efficiency.This paper takes typical colloidal phosphate ore as the research object,and specifically develops a novel plant gum settling agent that can achieve high-efficiency settlement of concentrate and tailings at the same time.The optimal conditions are explored and verified by industrial tests.Its good application effect can be widely used in the settlement of concentrates and tailings produced by colloidal phosphate ore beneficiation in the future.
