BIOLEACHING FOR THE RECOVERY OF METALS PEMISAHAN UNSUR LOGAM DENGAN BIOLEACHING

open access: yesBuletin Sumber Daya Geologi, 2015
A simple laboratory experiment has been conducted in order to demonstrate the ability of bacteria to leach the metal elements from insoluble ores or solid substrates. The experiment was conducted in a leaching column that was set up using 5 cc syringe that contained 1 cc of glass wool and 3.5cc of mine tailings.
