Study on Flotation Reagent of Multi-non-polar Radical Compound

A compound used as the collector and bubbler in coal flotaion was developed. This flotation reagent has more effective selectivity Compared with the conventional flotation reagents, the new flotation reagent is quite obvious to decrease the ash content of fine coal, and effective to save oil. A new sort of absorbing model was introduced. It is different from conventional model and the selectivity of the new kind of reagent was explained by this model.
