Aluminium dross initially is milled and screened sieve aperture 12mm Material above 12mm is fed in the furnace to produce metal aluminium, which is subsequently cast in ingots The melting process also produces some residual dross of very low grade, which is recycled into the process to recover as much of metal aluminium as possible...
temperature, a dry, insoluble, solid slag is formed When slag makes contact with the refractory lining of a furnace wall or other areas of the holding vessel that is colder than the melting point of the slag, the slag is cooled below its freezing point and adheres to the refractory lining This adhering material is ,...
