Performance of Collector H2

Processing parameters for flotation of gypsum and quartz with H2-Z as the collector were studied When used to treat pure minerals,H2-Z showed little selectivity and a quite good floatablity at pulp p H ranging from 3 to 10,and a better flotation performance was obtained at p H of 1 5 to 2 5,achieving separation between gypsum and quartz The actual ore flotation test ,...
