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 cobaltGet Price
Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. The bacterial leaching process is very slow compared to other methods. The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women.Get Price
