Acid mine drainage, ore processing and different metal extraction operations during copper ore mining cause severe environmental pollution problems like the contamination of surface and mine water with high loads of heavy metal which is furthermore a great loss for the copper mining industry. Several techniques for the removal of heavy metal from such wastewaters have been described. One of those techniques is the use of biological processes to produce metal sulfide nanoparticles with semiconductor characteristics. Hence, the purpose of this study was to improve the understanding regarding the biological synthesis of nanoparticles and by this means to produce copper sulfide nanoparticles from mine wastewaters. Using acid mine drainage of Sarcheshmeh Copper Complex (Kerman, Iran) copper sulfide nanoparticles were synthesized biologically. In this process Fusarium oxysporum was added to the …
