| Zusammenfassung: | The invention relates to an ore dressing method for recycling sulfur and arsenic from tin-lean multi-metal sulfide flotation tailings. The method comprises three stages ore dressing processes of magnetic dressing, flotation dressing and gravity dressing, wherein magnetic dressing tailings in first-stage low intensity magnetic dressing and second-stage middle intensity magnetic dressing is fed into sulfur and arsenic mixed rough flotation dressing operation; rough dressing finished ore is fed into sulfur and arsenic mixed finish flotation dressing operation and tailings are fed into sulfur and arsenic scavenging operation; sulfur and arsenic scavenging middlings return mixed rough flotation dressing operation; sulfur and arsenic mixed finish flotation dressing finished ore is fed into sulfur and arsenic separation rough flotation dressing operation and middlings return mixed rough flotation dressing operation; separation rough flotation dressing takes Y-As and sodium humate as combined collecting agent; rough |
