Abstract

A method and apparatus for implementing pyro-metallurgical processes, such as those involved in the reaction melting of fine grained solids or for the after-treatment of melts wherein an exothermically reacting solids/gas mixture is conducted through an acceleration jet as a heterogenous stream and is blown onto a melt contained in the furnace. The jet stream is ignited immediately upon discharge from the jet and a sharply focused or highly concentrated particle stream having a high surface power density (high mass flow velocity) and a high temperature is impacted against the melt. This results in the melt being subjected to localized intensive movement and is simultaneously heated. The method is suitable for the reaction melting of sulfidic or oxidic non-ferrous metal concentrates as well as for the reduction and/or depletion of non-ferrous metal containing slags, and for the reduction of metal melts.
