disadvantages and advantages of phytomining copper

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

Copper recycling and sustainability Benefits of recycling

Copper recycling and sustainability Benefits of recycling

Recycling copper uses much less energy, about 10GJtonne, thats only 10 of the energy needed for extraction. This energy saving leads to the conservation of valuable reserves of oil, gas or coal and reduces the amount of CO 2 released into the atmosphere. Conservation of copper ore To date only about 12 of known copper resources have been mined.

Prior to the development of the solvent extraction-electrowinning SXEW process in 1959 see Copper the Green Metal, the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect traded for iron by contacting the copper-bearing solution with scrap iron.
