recovery of iron in copper tails

  • Recovery of Iron from Copper Tailings by Direct Reduction

    Direct reduction of copper tailings were performed to recover iron efficiently by carbon-containing pellets, and the metallization rate was gained by chemical analysis method. The results showed that the metallization rate of copper tailings was up to 85.32% and the best reduction parameters are also found.
