<p>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 ) without melting 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.</p> |
