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.

At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today.
