Process for oxygen sprinkle smelting of sulfide concentrates |
摘要 |
Method for producing a metal matte from a nonferrous metal containing sulfide concentrate in a reverberatory type furnace by sprinkling a mixture of sulfide concentrates, flux and an oxygen-rich gas as a plurality of paraboloidal suspensions into a hot sulfur dioxide-rich atmosphere above the slag phase of the furnace charge. By introducing the concentrate, flux and oxygen-rich gas in such a manner, oxidation of the sulfide is effected prior to contact with the slag phase and substantially uniform heat and mass distribution are present throughout a major portion of the furnace. Coal is optionally introduced in a homogeneous mixture with the concentrate if nonautogenous operation is desired or slag cleaning is carried out to produce a discardable slag.
