Abstract
The process is for thermally treating a feed material. The process comprises at least one step performed in a rotating kiln operating under positive pressure with a pressure control system and wherein in the process a sweep gas, that is an inert gas or a substantially non-reactive gas, is injected into the rotating kiln or in the feed stream entering the rotating operating kiln; or at least one step performed in a rotating kiln operating under positive pressure managing system; or at least one step performed in a rotating kiln wherein a sweep gas is injected in the rotating kiln or in the feed stream entering the rotating operating kiln.
