摘　　要：为解决酒钢冶金厂区选矿废石堆存引起的安全、环保及生产难题,通过研究废石的相关物性,结合硅酸盐水泥工艺对生料的物质需求,探索生产配方。研究表明废石是硅酸盐水泥行业理想的铁质原料,10 mm以上废石做水泥铁料属于行业先进技术。In order to solve the safety,environmental protection and production problems caused by the waste rock storage in the metallurgical plant of Jiu Steel,by studying the related physical properties of waste rock,combined with the demand of Portland cement technology for raw materials,to explore the production formula.Research has shown that waste rock is an ideal iron feedstock for the portland cement industry,the technology is the first to use waste rock above 10 mm as iron material of cement.
