| Abstract Scope |
An efficient method of separating valuable elements (copper, cobalt, chromium and sulphur) from copper smelting slag of Luanshya district of the Copperbelt province in Zambia has been developed. The as-received slag material was characterised via scanning electron microscope. The valuable elements were separated through a combination of magnetic separation, flotation and gravity separation steps. Magnetic separation of the as-received material separates cobalt/iron and copper/sulphur/chromium rich fractions due to differences in magnetic properties. Residual copper in the magnetic fraction was upgraded to more 25 weight % via flotation. By comparison, flotation of the non-magnetic fraction yielded low grade copper concentrate due to high presence of sulphur. Chromium was upgraded by a factor of more than 5 when the non-magnetic fraction was subjected to gravity concentration. The effect of particle size was studied during magnetic separation of feed material. |
