The present study focuses on the experimental investigation of sulphatizing roasting of flotation tailings from copper slag processing using iron (II) and (III) sulfates followed by water leaching.
This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 and 2017). The first campaign was carried out using an existing copper slag flotation circuit in the plant.
Attempts have also been made by several researchers to prepare copper slag-derived ceramics [22][23][24][25]. However, this recycling method causes a waste of valuable metals since copper slag ...

Flotation was selected as a process for processing the slag with the aim of recovering copper. Flotation test showed that the recovery rate of copper depends on portion of fine grinding,
130 Metall. Mater. Eng. Vol 21 (2) 2015 p. 127-141 Based on the dependence shown in Figure 3 and the known degree of fragmentation in flotation, efficiency of copper recovery is 89%.
In this study, a facile process for recovering copper from copper slags through flotation enhanced by sodium carbonate synergistic mechanical activation has …
Copper slagCopper slag is a major waste produced in pyrometallurgical plants during the smelting and converting operations and has caused heavy environmental contamination. A pyro-hydrometallurgical process for the treatment of copper slagCopper slag has been...
The researchers reported that particle size, reagent type, reagent dosage and slurry pH are the significant operating variables governing the flotation of copper slag. …
Commonly Used Mineral Processing Equipment for Copper Slag Crushing Equipment. At present, it mainly uses jaw crushers. The application of other crushing equipment with high efficiency and large crushing ratio, such as deep cavity jaw crushers, double-moving jaw crushers, inertial cone crushers, etc., is also receiving increasing …
In this study, a hydrometallurgical method for the recovery of copper, cobalt, and zinc from copper slag flotation tailings (SFT) was investigated. SFT contains large amounts of valuable metallic compounds, such as copper, cobalt, and zinc. A representative SFT sample containing 0.50% Cu, 0.148% Co, 3.93% Zn, and 39.50% Fe was used in …
