Bioleaching Wikipedia

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

Industry TECHNOLOGY FOR LIFE

Sep 07, 2018 · If in the past, the low grade ores were considered as waste rocks which means that they can't be processed any further, with heap leaching, it's possible to process those ores. Therefore, more results are gained. Even further about the heap leaching method, as a matter of fact, there are several more specific processes which can be done.
