摘要
According to an embodiment of the present invention, a manufacturing method of ferrosilicon from silicon sludge and mill scale comprises the following steps: producing a mixture by mixing silicon sludge and mill scale which contains iron oxide (step 1); heat-processing the obtained mixture in an inert gas atmosphere (step 2); and cooling the heat-processed mixture into a predetermined temperature, and separating slag (step 3). Silicon and iron can be used as resources again through the method of the present invention.
