Recovery of copper from a surface altered chalcopyrite

Hydrometallurgical processing of chalcopyrite has limitations due to slow dissolution kinetics [3 17 18] Thus a rapid dissolution rate of chalcopyrite using acidophilic iron and sulphur oxidizing bacteria is the need of the day On the other hand Rao et al [17] reported that the bacterial leaching phenomenon/action is limited to the material surface which ultimately upshots poor copper
