With large amounts of water used for mine drainage, mine cooling, aqueous extraction and other mining processes, increases the potential for these chemicals to contaminate ground and surface water. As mining produces copious amounts of waste water, disposal methods are limited do to contaminates within the waste water.
Modern biomining processes are largescale operations that involve the mining of ores and processing for several months (Fig. 1). Either through stripmining or blasting, raw ore is obtained for extraction of copper.

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
