A slag containing a metal fraction is passed through a magnetic separator A to provide a fraction(s) containing an enhanced content of metal and a waste product with reduced metal content. The metal containing fraction(s) is then passed through a separator B containing a trough 10 having an endless path and containing dry sand, the floor 11 of the path being air permeable and including a depthwise partition 12, the metal and non-metal components being separated according to their density. <IMAGE> |
