  • Method of solidifying the slag obtained in ferrochromium production
    Patent number: 4124378
    Abstract: During ferrochromium production, boron oxide B.sub.2 O.sub.3 is added to the charge when melting the ferrochromium in the electric furnace. This boron oxide will be added in the form of dried chemical discards resulting from the production of boric acid and/or borax, the said discards containing 2% to 7% of boron oxide.The boron oxide can also be added in the form of boron ore, advantageously containing more than 30% of boron oxide. The said discards are added in the proportion from 1/20 to 1/50, and preferably 1/30 part by weight of the charge; and moreover, the amount of the lime to be added to the charge will be reduced by the amount of the lime already contained in the added discards as obtained by production of boric acid and/or borax.The ore is added in the proportion of 1/200 to 1/500, and preferably 1/300 part by weight of the charge.
