Most copper ores are sulphur-based and smelting releases sulphur dioxide, an air pollutant known to have many harmful effects. Sometimes, depending on the quality of the ore, the concentration of sulphur dioxide is so high that industries are forced to convert it into sulphuric acid, which itself is a water contaminant.

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.

It was demonstrated that increased concentrations of plant extract speed up the rate of reduction of copper ions in the solution, which directly increases the formation rate of Cu and CuO NPs . This is attributed to the phytochemicals present in the plant extract, which are responsible for the bioreduction and stabilization of the NPs [ 80 ].
