Adsorption changes of starch on minerals in carbonate

Adsorption changes of starch on minerals in carbonate

Starch exhibits excellent adsorption performance on hematite at a slightly alkaline pH. The flotation of hematite is depressed with dodecylamine acting as a collector, however, the flotation of quartz is minimally influenced. Thus, starch is commonly used to depress the flotation of iron minerals in the reverse flotation of hematite , .
