A method of fabricating a cordierite article from one or more steel slags such as blast furnace slag, converter slag and electric furnace slag.

The device for realising this method comprises a slag container for liquid slag with an outlet opening (2) for said liquid slag.

The remaining slag in the3 slag pot is poured down a subsequent ramp (30), resulting in a metal rich slag.

Optionally, the latter step is repeated with any slag remaining in the slag pot (20).

The slag then flows out of the chambers.

The method comprises transferring the hot metal dross in a dross pan and placing the dross pan with the metal dross therein in the gastight chamber.

According to said method the slag drips in liquid form onto a vibrating, cooled grid which is covered with a slag layer on the basis of crushed and cooled recycled slag.

The ingot and the slag can be recycled.

The slag is subsequently separated from the melt.

The outer ends of the grate bars (40) are equipped with slagging boards or slagging teeth (5).

The resultant synthetic blast furnace slag is then discharged.

The slag burning apparatus solves the technical problems of incomplete combustion of fuels and slag accumulation in existing biomass boilers.

The use of an inert metallic conductor in the slag-containing crucible and the addition of a transition metal oxide to the slag are the disclosed process improvements.
