  • Method of refining mattes containing nickel
    Patent number: 4045215
    Abstract: Nickel-containing mattes are desulphurized down to low sulphur levels (less than 1%) in a multi-stage process effected in a single converter vessel. In the first stage, an oxidizing gas is blown into the molten matte to reduce the sulphur level to about 4 to 7% and in one or more subsequent stages, oxygen and a diluent are blown into the matte, with a peripheral flow of protective fluid to protect the tuyeres against wear. The diluent, which may be argon or steam for example, dilutes the sulphur dioxide in the matte.
