Abstract:
A method is provided for producing matte such as copper or nickel matte or crude metal such as blister copper in a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace. Also provided is a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace. The suspension smelting furnace comprises a reaction shaft, a settler in communication with a lower end of the reaction shaft, and an uptake shaft. The settler extending in two opposite directions from a landing zone for a jet of oxidized suspension below the reaction shaft in the settler so that the settler comprises a first settler part on a first side of the landing zone and a second settler part on an opposite second side of the landing zone.
