  • Selenium Recovery in Precious Metal Technology

    Selenium is mostly extracted from copper anode slimes because the selenium-rich ores are too rare to be mined with profit. When copper anode slimes are processed in a precious metal plant the first step is to remove copper by pressure leach in an autoclave. The anode slime

  • Biobeneficiation of Iron Oressapub

    Iron ore fines and slimes present in tailing dams can be efficiently agglomerated and stabilized using native microorganisms from an environmental angle. Also such bioprocess would pave the way for recovery of valuable minerals from wastes and for reharvesting and recirculation of process water.
