Abstract

An apparatus for separation and recovery of a molten metal (106) from a slag (108) includes a device (400) attached to a slag ladle (100). The device having a lower edge (404) and free edge (402) is fitted over a part of the slag-ladle holding the molten metal (106) and the slag. The device acts as a barrier for the flow of molten iron such that the slag is allowed to flow over the device while the molten metal is retained in the slag-ladle. The device has a sluice gate (406) and a chute (408) for indicating the flow of the slag in the form of a pipe-like stream. A method for separation of molten metal from slag is based on the above apparatus. The device differentiates the rnomentums of flow of molten slag and molten metal during slag pouring process and prevents the flow of molten metal associated with the molten slag along with the flow of molten slag during the slag pouring process and collection process thereafter.
