摘　　要：以废加氢催化剂、废汽车催化剂为原料,利用红土镍矿调整熔炼渣型,采用还原熔炼综合回收各物料中的有价金属,并系统研究了各工艺条件对有价金属回收率的影响。结果表明,在红土镍矿配比1.5∶1、CaO添加量7.5%、熔炼温度1525℃、保温时间2 h的优化条件下,渣计Ni、Mo、V的回收率分别达到96.82%,96.66%和89.69%,同时贵金属Pt、Pd和Rh回收率分别达到90.19%,98.00%和94.85%,实现了原生矿与多源固废协同处置综合回收有价金属的目的。Spent hydrodesulphurization catalysts and spent automotive catalysts were used as raw materials to recover valuable metals from multi-source spent catalysts by reduction smelting applying laterite nickel ore to adjust slag composition.Effect of various conditions on recovery rate of valuable metals was systematically researched.The comprehensive experiment results show that recovery of Ni,Mo,V calculated by slag is 96.82%,96.66%and 89.69%,respectively,and the recovery of Pt,Pd,Rh is 90.19%,98.00%and 94.85%,respectively,under the optimum conditions including mass ratio of ore to spent catalysts of 1.5∶1,mass ratio of CaO to spent catalysts of 7.5%,smelting temperature of 1525℃,and smelting time of 2 h.This process realizes the purpose of co-processing of primary ore and multi-source solid wastes to recover valuable metals.
