Abstract
In a process for deoxidizing copper by the violent intermixing of the bath of copper with a molten and fluid slag capable of absorbing the oxides contained in the metal, a metalloid whose oxidation product is more readily absorbed by the slag than copper oxide, is added to the metal bath before or during intermixing or between two successive intermixings, the quantity of metalloid added being lower than that for which the solubility at saturation in the copper of the oxidation product of said metalloid would be exceeded. Examples of such metalloids are phosphorus, silicon and arsenic and the amount used is less than 5 per cent. The slags used contain lime as the main constituent together with oxides of manganese, sodium, iron, magnesium, and aluminium. Specification 409,911 is referred to.
