铅锌尾矿制备水泥熟料及重金属固化特性OA北大核心CSCDCSTPCD
Solidification of heavy metal and production of cement clinker by lead-zinc tailings
以桥口铅锌尾矿为原料制备水泥熟料，主要研究生料的易烧性、熟料的重金属固化、浸出毒性及水泥的强度。利用X线衍射(XRD)和扫描电镜(SEM)分析不同尾矿掺量及煅烧温度下水泥熟料的矿物相和微观结构，用电感耦合等离子体原子发射光谱法(ICP−AES法)分析熟料中重金属的质量分数。研究结果表明：当煅烧温度超过1350℃且加入铅锌尾矿质量分数为15%~16%时，可生产出符合GB 175—2007标准的硅酸盐水泥，其硅酸三钙(C3S)质量分数最高可达49.2…查看全部>>
Taking Qiaokou lead-zinc tailings as a kind of main raw materials to produce cement, the burn-ability of raw meal, the heavy metal curing, leaching toxicity and the strength of clinker were studied. The mineral phases and microstructure of cement clinker were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively, and the mass fractions of heavy metals in clinker were analyzed by the method ofICP−AES. The results show th…查看全部>>
