Abstract
The invention relates to a method for controlling suspension in a suspension smelting furnace. The method comprises feeding additionally to pulverous solid matter and additionally to reaction gas reducing agent into the suspension smelting furnace, wherein reducing agent is fed in the form of a concentrated stream of reducing agent through the suspension in the reaction shaft onto the surface of the melt to form a reducing zone containing reducing agent within the collection zone of the melt.
