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.
