Abstract

PURPOSE:To obtain inexpensive copper-contg. iron with less resources and energy by adding copper concentrate and its roasted ore into molten iron, and if necessary, subjecting the iron to a desulfurization treatment. CONSTITUTION:At least one kind of the copper concentrate obtd. by flotation or the like, or the roasted ore prepd. by oxidation roasting of this is added at about 80kg per ton of blast furnace molten iron into the molten iron in a ladle during tapping. If necessary, the molten iron added with this is subjected to a desulfurization treatment. Since in this method the copper concentrate and the roasted ore are used in lieu of copper base metal, the cost of the copper-contg. iron is reduced. It is possible to decrease the amt. of S easily through ordinary desulfurization treatment despite the increase in the content of S in the molten iron by adding the copper concentrate.
