By way of example, a copper concentrate could include chalcopyrite (CuFeS2), containing 34.6% copper, possibly another sulphide such as pyrite (FeS2) and other waste (or gangue) minerals. The overall grade of the concentrate could be in the range 22% to 30% copper. Concentrates are usually specific to particular smelters.

 — In theory, this surplus will support higher copper treatment and refining charges in the years to come. Final word. Base metal smelters assess a myriad of charges and deductions to ensure the value of their operations. Base treatment charges form the bulk of that value and are the primary focus of contract negotiations.

 — The purpose of smelting is to enrich most of the copper in the copper concentrate in the matte phase. The gangue, oxides and impurity elements were combined in the slag phase to completely separate the copper matte in the slag phase. In this paper, a mathematical model based on the optimization of copper concentrate cost and the …

 — Copper concentrate quality drivers. CRU data shows that the average copper concentrate grade has declined by 7% since 2007 (from ~27% to ~25% Cu content). The grade of the concentrate is primarily driven by the mineralogy of the copper deposit, as well as the success rate (recovery) of metal during beneficiation.

 — The copper values present in the slag, either as independent metallic particles or in the form of sulphides, can be floated effectively. ... Another flotation study on the modified copper slag under optimized conditions reported the improvement of the copper grade of the concentrate to 11.04% from a feed of 0.8%, while the unmodified …
