Abstract: A method for recovery of metals or metal compounds from metal-bearing solid particles comprising volatile compounds comprises supplying the solid particles (50) through a flame (25) of a burner (20). The volatile compounds are then evaporated by means of heat from the flame (25) while maintaining the original shape and state of aggregate of the solid particles, thereby providing a raw material product (34). The raw material product (34) is then recovered. By feeding the solid particles directly to the flame, a compact and efficient plant is provided. The melting process can be controlled in a satisfying way, avoiding melting of the metal-bearing solid particles supplied through the burner. The use of a burner is also described.

Abstract: The present invention concerns a process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step (1) made in a first roasting reactor (16) and a second roasting step (3) made in a second roasting reactor (17). A gas mixture is formed from the first process gas component (2) obtained from the first roasting step(1)and from the second process gas component (4) obtained from the second roasting step (3). Post combustion of the gas mixture is made in a post combustion chamber (6). The post combustion operates with said reducing and sulphide rich first process gas component (2) and the second process gas component (4) as oxidizer gas in order to decompose SO 3 in the gas mixture to reduce the SO 3 content. The risk of accretion formation and corrosion in the post combustion chamber and in subsequent steps is reduced. Finally the exit gas (7) is exposed to subsequent gas cooling and dust removal steps (8 to 11).
