Study on Floatability and Separation of High Ash and Difficult Floatable Coal

Abstract:

According to the actual demand of scare coal resources in our country, there is a vital significance in the study on strengthening separated process of high ash and difficult floatable coal. In terms of the limitations and deficiencies of process intensification and flotation efficiency at home and abroad, by means of experimental and analytical approaches, the surface properties of scarce coal slime separation process and process intensification were focused on in this paper. The association between mineral dissemination and variation during flotation process was also focused on. The superficial properties of difficult floatable coal slurry and the existing problems of the traditional reagents in the separating process of difficult floatable coal were analyzed. The reagents dosages suitable for coal slime with high ash were proposed. In the process, kerosene and octanol were respectively taken as collector and frother. The conclusions were obtained that kerosene dosage was 320g/t, Octanol dosage was 110g/t, flotation concentration was 100g/L, and inflation volume was 0.37m3/m2•min.
