| Abstract: | This paper assays the contents of sulfur,ash,and major minerals in No 3 Hongyang mine's coal of Shenyang mining bureau, and studies the relationship of desulphurizing percentage and deashing percentage with reagent dosage by desulphurization of the coal sample with culture medium and various domesticated microbials. The authors point out that the most appropriate dosages of kerosine as collector and terpenol as frother are 121 g/t and 32 g/t, respectively, whether culture medium or various microbials is used to desulphurize the coal sample. |
