Definitions

  • Fig. 2 is a cross-sectional view of the apparatus shown in Fig. 1 taken along line A-A.
  • the bay area 12 be totally clear of water, puddles of water and moisture before dumping the liquid slag thereon or an explosion may occur. Additionally, the trough area 14 should also be free of water or puddles of water in case the liquid slag runs off the bay area 12 and into the trough area 14.

Abstract

L'invention concerne un appareil (10) et un procédé pour séparer des scories riches en métaux et des scories pauvres en métal. Un pot à scories (20) permet de refroidir partiellement, et d'agglomérer le métal dans le pot. Une partie des scories partiellement refroidie est versée le long d'une première rampe (26), produisant des scories pauvres en métaux. Eventuellement ces scories sont refroidies avec de l'eau. Les scories qui restent dans le pot à scories sont versées le long d'une rampe suivante (30), donnant lieu à des scories riches en métaux. Eventuellement, on répète cette dernière étape avec toutes les scories restantes dans le pot à scories (20)
