Phosphorus (P) is a primary constituent of plant and animal life. This element plays multiple roles in plant metabolism and is one of the essential nutrients required for plant growth and ate rock minerals are the only significant global sources of ate rocks are important in different industries as phosphoric acid, fertilizers and elemental.

Two types of bacteria, Corynebacterium-diphtheriae-intermedius (CDI), and Pseudomonas aeruginosa (PA), were used. The collector-bacteria interaction was characterized by Fourier transform infra-red (FTIR), frothing height and Zeta potential. The results show that the collector-bacteria interaction improves the flotation selectivity.

This book is the exclusive source of information on research and technology advances in phosphate mineral processing. More than internationally respected authors from 20 countries explore the latest developments in an industry experiencing unprecedented change and prosperity.In this study, the effect of sodium pyrophosphate (NaPP) on the separation of apatite from dolomite by flotation was systematically investigated.

Flotation results revealed that NaPP could selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite. Further, the selective depression mechanism of NaPP was studied through zeta potential measurements.The first flotation separation for the rejection of magnesite was reported by Doerner and Dwigh (s) [].Flotation of Mg carbonates is typically carried out by using fatty acids, since these collectors give insoluble complexes with all divalent cations [].Determination of the appropriate depressing reagents for sinking valuable minerals in the presence of collectors for carbonates is a.
