A method for processing a powdery material, wherein said material is contacted with a non-aqueous liquid substance heated by combustion gases and comprising at least 30 % by volume of a predominantly oxidised material, substantially without exposure to the gaseous atmosphere that may contain said combustion gases, and in such a way that the amount of dust released by said powdery material is minimised, and said substance is maintained at a temperature at which the substance is able to form a liquid phase with the powdery material. |
