| Abstract: | Nanocellulose, an environmental friendly material derived from natural resources, has been considered a promising alternative collector for flotation. In this study, nanocelluloses were prepared via acid hydrolysis from cotton, followed hydrophobic modified with trimethylchlorosilane (TMCS). Then, the hydrophobicity nanocelluloses were used as a collector for coal flotation. The results showed that the combustible matter recovery can reach 86% in the condition of the cellulose dosage is 1.0 kg/t and the amount of kerosene is greater than 0.6 kg/t. The synergistic effect of nanocelluloses and kerosene significantly higher than the individual using situation. The contact angle measurements and SEM analysis showed that nanocellulose not only enhances the hydrophobicity of coal but also increasing surface roughness by deposition on coal surface. This work is anticipated to provide a promising flotation strengthening agent for recovering coal. [ABSTRACT FROM AUTHOR] |
