ABSTRACT:
Molten molybdenum-(copper)-iron-sulfur mattes or alloys, obtained for example, by reacting slags or other molybdenum containing oxide residues or waste materials with an iron and/or sulfide reductant, are enriched in molybdenum and copper (if present) by a pyrometallurgical process. The molten matte or alloy material is oxidized to remove sulfur, as sulfur oxides, while varying amounts of iron are converted to iron oxides which separate from the metallics. The oxidation thus enriches the molybdenum and copper content of the remaining alloy. Silica flux may be added during the reaction process to form a fluid slag with the iron oxide which separates from the remaining molybdenum-iron-(copper) material which constitutes the product.
