Abstract
1535970 Extraction of metal from a melt P A WRIGHT 3 March 1977 [18 Feb 1976] 06340/76 Heading C1A A metal is extracted from a melt containing the metal by injecting into the melt a thermally balanced mixture comprising a mixture of sulphur dioxide with air or oxygen and a gaseous or liquid hydrocarbon to form a sulphide of the metal, the said melt being capable of reacting with gaseous sulphur produced from the sulphur dioxide to form a said sulphide, and the proportions of the components of the thermally balanced mixture being such that the gaseous reaction products from such a mixture shall have a minimum temperature determined by the liquidus temperature of the melt into which said reaction products are to be injected or the liquidus temperature of the products of reaction between the components of the melt and the injected gaseous reaction products, whichever is the greater, and that the partial pressure of oxygen in such gaseous reaction products is in accord with the desired composition of the melt. The thermally balanced mixture may be generated from sulphur dioxide recovered from exhaust gases. Recovery of tin from slags is exemplified, the thermally balanced mixture being introduced into a slag bath through at least one tuyere or injection lance which is independent of the main furnace heating system.
