Bioleaching

Bioleaching is a part of microbial mining In microbial leaching or bioleaching metals can be extracted from large quantities of low grade ores This process has been used for centuries to recover copper form the drainage water of mines the role of microbes in the bioleaching came into notice some 40 years ago

Copper mining Introduction

The main ores of copper are chalcopyrite bornite malachite The ores are extracted by either traditional mining (open pit or underground) or by leaching The copper is then recovered using physical and chemical techniques In this electronic resource we'll look at the ways in which copper is mined and recovered from its ores
