copper bioleaching behaviour in an aerated heap

this is a study of a field test carried out to correlate heap aeration with copper bioleaching. a 62500-t portion of a production leach pad was monitored for oxygen levels copper content and bacterial activity at different heap heights during bioleaching. different rates of forced aeration were applied to this test heap.

copper extraction - wikipedia

the treated ore is introduced to a water-filled aeration tank containing surfactant such as methylisobutyl carbinol (mibc). air is constantly forced through the slurry and the air bubbles attach to the hydrophobic copper sulfide particles which are conducted to the surface where they form a froth and are skimmed off.

history of forced aeration in copper sulfide leaching

the development of forced aeration as an approach to enhancing copper sulfide leaching is traced from its earliest development to present day operations. both large-scale field tests and commercial operations are covered. the historical portion is preceded by an introductory discussion of the role of air (oxygen) in sulfide leaching.

enhanced column bioleaching of copper sulfides by forced

to assess the effects of forced aeration on leaching dynamics of sulfides five sets of column bioleaching of copper sulfides using acidithiobacillus ferrooxidans were conducted when the aeration rates ranged from 0 to 150 l/h. the experimental results show that forced aeration can ameliorate the porosity and flow rates throughout the heap and improve the bacterial concentration and oxidative
