ABSTRACT:
A continuous process and apparatus for converting non-ferrous mattes is disclosed. The process comprises feeding continuously or intermittently a liquid matte into a furnace while continuously blowing air, oxygen or oxygen-enriched air into the melt contained in the furnace at a rate in balance with the rate of liquid feed matte and the desired degree of oxidation, introducing flux into the furnace at a rate in balance with the feed matte and air, oxygen or oxygen-enriched air, and removing slag from the top of the melt and a refined product from beneath the melt while continuously blowing air, oxygen or oxygen-enriched air through the melt.
