Biomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes fungi or plants ( phytoextraction also known as phytomining or biomining). 1 These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used
A small copper concentrator produced approximately 100 000 cubic yards of tailings. A nearby residential area expressed serious reservations about these tailings and as a result the mining company plans to move the tailings using a slurry approach to a place where a copper smelter is located. These copper
