【摘要】 与天然石膏不同，磷石膏中杂质赋存状态复杂，分为无机类（硅、磷、氟、铁等）和有机类（腐殖质、浮选药剂等），难以直接利用。概述磷石膏的综合利用途径和除杂方法，提出应继续推进磷石膏综合利用并开发环保、经济的新工艺，实现大宗固废资源化利用。更多还原

【Abstract】 Different from natural gypsum, phosphogypsum is difficult to be used directly because it contains complicated impurities, which can be divided into inorganic(silicon, phosphorus, fluorine, iron, etc.) and organic(humus, flotation agent, etc.). The comprehensive utilization and impurity removal methods of phosphogypsum are summarized. It is suggested that we should continue to promote the comprehensive utilization and develop environmental protection and economic technology to realize the utilization of bulk solid waste resources.更多还原
