LOW COST METHOD OF FLUIDIZING CUPOLA SLAG (A) ABSTRACT OF THE DISCLOSURE A method of fluxing and fluidizing the slag in a cupola by adding to the charge therein a fluxing material comprising, by weight percentage relative to the metal charge, 3-5% CaCO3 (limestone), 3-5% MgCO3 . CaCO3 (dolomite), and 1-2% Na2CO3 (fused soda ash). This fluxing and fluidizing material is used for operating a basic cupola and is used in amounts ranging from about 7 to 12 by weight of the metal charge. The flux material serves to remove impurities from the metal, and improve the combustion efficiency of the coke. In an acid slag cupola, the flux will increase fluidity. In a basic slag, a fluidizer serves to improve the fluidity of the slag, while offering no injurious by-products that would interfere with emission control elements, and additionally insures a lower cost fluxing material as compared to current basic operated cupola practices.
