Thus, bottom slag needs smaller liberation size for separating the unburned carbons. By contrast, the froth flotation separation technology is highly accepted for separation of small particle sizes (range) and effectively used for coal cleaning. Froth flotation is a highly versatile method for separating particles.

Ti-extraction blast furnace slag (EBFS) is a secondary slag produced by titanium extraction of titanium-bearing blast furnace slag (TBBFS), which is challenging to be used directly because of its residual carbon and chlorine. This study was performed to recover the residual carbon and remove chlorine from EBFS by froth flotation.

After copper recovery by flotation, the remaining part of the slag is considered waste and disposed of in the slag dump area. However, even after copper recovery, copper slag flotation tailings (CSFT) may still contain several metals in varying amounts. However, the complexity and low metal concentration have undermined the …

In this context, microscopy analysis of slag samples was carried out in order to determinate its mineralogical composition and to find a possibility for re-extraction of remaining copper from the slag. According to results of the investigation and phase occurrences in slag, it is possible to apply flotation for recovery of copper from these slags.

During this process, the copper concentrates reacts with oxygen enriched-air producing copper matte, iron oxides and sulphur dioxide which causes it to directly be oxidized and be separated into matte and slag when melted. It is skimmed off and is moved into the Slag Flotation Plant (SFP).
