Document Type and Number:

Japanese Patent JP2002544390

Kind Code:

A

Abstract:

The present invention relates to a method and equipment, whereby matte with a high non-ferrous metal content and disposable slag are produced simultaneously in a suspension-smelting furnace from non-ferrous sulphide concentrate. According to the invention, a carbonaceous reducing agent is charged to the lower furnace of a suspension smelting furnace via tuyeres to the part of the furnace which has a reduced cross-sectional area.
