Production of copper cathode through Tank Bioleaching method.

In this method, copper cathode production is carried out using thermophilic microorganisms in an acidic solution through dissolving copper sulfide concentrate. Subsequently, through solvent extraction and electrowinning methods, copper of Grade A quality as per London Metal Exchange (LME) standards (with a purity of at least 99.995%) is produced under the ASTM B115 2016 standard.
