  • The recovery of copper, by flotation, from calcium-ferrite ...

    A series of batch laboratory flotation tests was conducted on a suite of different calcium-ferrite slags made in continuous pilot plant smelting trials. The slags included a moderately reduced low copper slag, a more oxidised high copper slag, a very reduced low copper self-pulverising slag, and a moderately reduced low copper Escondida slag.
