Biodegradation studies on fatty amines used for reverse

2010-3-1  After amines are used in industrial flotation processes, such compounds are released to the tailings dam and remain there. It is estimated that approximately 5500 tons of amine derivatives per year are used in flotation processes only in Brazil. With the ongoing world demand for iron ore, amine consumption tends to constantly increase.get price

The Effect of New Modified Fatty Acid (CY-23) Collector on

The flotation separation on chlorite and hematite with the new modified fatty acid collector CY-23 was studied. The investigation included both flotation and reagent adsorption tests. And all the characteristics of chlorite surface before and after the adsorption of new collector CY-23 have been studied with X-ray photoelectron spectroscopy (XPS). The flotation results showed that caustic starch (CS) could depress the flotation of hematite and chlorite and CaCl2 could activate chlorite flotation but failed on hematite w[PDF]
