Combination Collector Mechanism--Chelating Effect
In the flotation system, two or more collectors are used in combination, and by combining the collector and producing synergistic effects, such tungsten ore flotation collector is known as combination collector in practice. It has been proved that many combination collector has better and more effective flotation results than the use of a single collector, and there are divergent views on the causes. For the study of the mechanism of the combination collector, there are scholars think that the combination collector also has a significant chelating effect, it refers to the combination collector and mineral surface of the metal between the combination collector metal's special affinity caused by the real chemical reaction. The result of this reaction is the formation of insoluble, stable metal chelate. The scholars of South China University used the quantum chemistry ab initio algorithm to calculate the molecular model of benzohydroxamic acid and benzyloxamic acid. T...
