To compact the particles, the box 10 may be vibrated vertically or horizontally, and/or a weight, spring or fluidpressure may act upon the top of the bed 14. Preferably the compacting means pushes some of the particles through the bottom of the box and into the bath, additional particles may be introduced through the top of the box. A non-oxidizing gas, e.g. propane, with a small amount of H 2 S may be introduced through slot 21 and cavity 20.
