Developments in the physiochemical separation of iron ore
2015年1月1日 The reverse cationic route is by far the most widely used iron ore flotation process. This process floats quartz with an ether amine collector at pH 10–10.5 using cornstarch to depress the iron oxides. In the early years, primary fatty amines, such as dodecylamine, were used, but these have now been replaced by the more soluble ether
