<p>PURPOSE: A processing method of industrial waste is provided to obtain environmentally friendly industrial material having a superior mechanical property by mixing industrial waste with methyl sulfonyl methane(MSM) which is represented by general formula sulfur(S). CONSTITUTION: A processing method of industrial waste comprises the following steps: mixing cinder or coal ash, steel-making slag, and steel-making dust in weight ratio of 35-50:10-15:15-25(S101); heating and drying the mixture(S103); mulling the dried mixture after heating(S105); melting the MSM by heating; mixed-melting the milled mixture with the melted MSM(S109); and cooling the mixture including the melted MSM(S111). In the mixed-melting step, 65-80 weight% of the milled mixture and 20-35 weight% of the melted MSM are mixed for 15-20min at 120deg.C.</p> |
