Extraction of copper from ore begins with pre-treatment. Due to the decreasing concentration of copper in ores, this is an important step to decrease the volume of material and to increase the grade of copper in the ore. Most copper ores will only contain a small percentage of copper mineral, with the average grade being below 0.6% copper.

In all areas copper ores have a relatively low copper analysis, in the range of 0.3–4% Cu. Many mines operate today on ores of 1% or lower copper content. Thus, a significant consideration for economical metal production is low-cost breaking up and removal of igneous rock, and recovery of the copper bearing mineral from this.
