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.
