磷尾矿综合利用研究现状
Research status on comprehensive utilization of phosphorus tailings
摘要
Abstract
Phosphate tailing s are solid waste produced after the beneficiation and enrichment of phosphate ore.Their long-term stacking will not only occupy a large amount of land,but also pose a serious threat to the soil and groundwa-ter environment,and because it contains a large number of valuable elements,it will also cause waste of resources.This paper introduces the source and harm of phosphate tailings,sorts out beneficiation processes of the main phos-phate ore in China,and summarizes the recovery methods of valuable elements in phosphate tailings,such as flotation method,chemical beneficiation method and magnetic separation method,etc.;The research status of phosphate tailings materialization application is reviewed,mainly including three aspects:preparation of building materials,such as geopolymer,cement,ceramics,etc.;preparation of functional materials,such as ceramsite,refractory,flame retardant,etc.;other aspects,such as roadbed materials,fertilizer,wastewater treatment and so on.Accelerating the formulation of new material standards and reducing the cost of comprehensive utilization on phosphorus tailings are problem that need to be solved in the future.关键词
