Study on Promoting Effect of Carboxylic Acid on Flotation of Low-rank Coal

Study on Promoting Effect of Carboxylic Acid on Flotation of Low-rank Coal

The surface oxygen content of low rank coal is high and the surface hydrophobicity is poor. It is difficult for diesel oil to adsorb on the coal surface efficiently. The reagent consumption is large and the flotation effect is not ideal. In this paper, diesel oil and carboxylic acid of oleic acid, l...
