Smelting method for converter steel slag resource production

The invention particularly relates to a smelting method for converter steel slag resource production, and belongs to the technical field of steel smelting. The method comprises the following steps that molten iron and scrap steel are mixed, and smelted molten iron is obtained; the smelted molten iron is subjected to converter blowing, and dephosphorized molten iron is obtained; wherein the total iron reduction blowing is started 0.5-1.5 minutes before the converter blowing is finished, the oxygen supply intensity of the total iron reduction blowing is 3.2 Nm /min/t to 3.4 Nm /min/t, the lance height of the total iron reduction blowing is less than or equal to 1000 millimeters, and the blowing time of the total iron reduction blowing is at least 30 seconds; the dephosphorized molten iron is subjected to converter tapping, and slag and molten steel are obtained; when smelting is finished, the total iron reduction blowing is carried out, so that the total iron content of the final slag is lower than 15%, and the
