with tungsten and tin mineral. Tungsten is predominately present in wolframite. Tin is predominately present in cassiterite. Adopting chlorination segregation method makes copper mineral phase change, but tungsten and tin mineral phases don’t be changed, thus the copper mineral is separated from tungsten and tin minerals. After the chlorination segregation-flotation-high intensity magnetic separation......

of recycling the zinc dross. With better ability of absorbing the microwave than zinc oxide, the main material in zinc dross, chlorides, can be heated and evaporated rapidly during microwave roasting. Various parameters including roasting temperature, duration time and stirring speed were optimized. The microstructure of roasted materials was characterized by X-ray diffraction (XRD) and scanning electron......
