一种冶金精炼废渣脱硫处理方法
摘要：
本发明公开了一种冶金精炼废渣脱硫处理方法，将冶金精炼废渣粉体与硫铁矿粉混合后，通过氧化焙烧进行脱硫，并对脱硫后剩余的渣料和产生的气体进行回收利用；其中，回收的渣料可用作冶炼助熔剂，回收的气体经净化、干燥、转化和吸收可制得成品硫酸；通过上述方式，本发明能够提高冶金精炼废渣粉的脱硫率，实现对冶金精炼废渣粉的高效脱硫及循环利用，并且通过对氧化焙烧产生的气体进行收集和再处理，制得了成品硫酸，既避免了其直接排放造成的污染，又提高了资源的整体利用率。
摘要（英）：

The invention discloses a metallurgical refining waste residue desulfurization treatment method which comprises the following steps: mixing metallurgical refining waste residue powder with pyrite powder, desulfurizing through oxidizing roasting, and recycling residual slag and generated gas after desulfurization, wherein the recycled slag can be used as a smelting fluxing agent, and the recycled gas is purified, dried, converted and absorbed to prepare a finished product sulfuric acid; by means of the mode, the desulfurization rate of the metallurgical refining waste residue powder can be increased, efficient desulfurization and cyclic utilization of the metallurgical refining waste residue powder are achieved, the finished sulfuric acid product is prepared by collecting and retreating gasgenerated by oxidizing roasting, pollution caused by direct emission of the finished sulfuric acid product is avoided, and the overall utilization rate of resources is increased.
