Optimization of a leaching process for copper-bearing mat...
The ore deposit of the European copper shale (kupferschiefer) is large sediment-hosted copper deposits with a high content of base metals, precious metals and PGM. The Copper shale ore possesses a large content of carbonate rocks up to 75% that hinders traditional bioleaching with acidophilic microorganisms. Therefore heterotrophic microorganisms were examined with respect to metals leaching at neutral pH to ...
