Methods for Analyzing the Composition of Steelmaking Dust and Methods for Recycling Steelmaking Dust

Abstract

This invention provides a method for determining the composition of steelmaking dust rapidly and with good accuracy. The method comprises: a dust preparation step of preparing steelmaking dust with a moisture content of less than 10 wt%; a particle size adjustment step of adjusting the particle size of the steelmaking dust to form an analytical sample; and an analytical step of analyzing the composition of the steelmaking dust using the intensity of fluorescent X-rays from the analytical sample; wherein the maximum particle size of the analytical sample is less than 2 mm, and the powder satisfies the following formulas (1) and (2): (W1+W2) / W≦0.70･･･(1) 0.50≦W1 / W2≦0.75･･･(2)
