J. Cent. South Univ. (2012) 19: 1206-1211 DOI: 10.1007/s11771-012-1130-2 Influence of surface roughness on flotation kinetics of quartz M. Rahimi1, M. R. Aslani2, B. Rezai1 1. Department of Mining... product. For the particles with larger surface roughness, the flotation kinetics constant is also higher. Finally, empirical relationships between surface roughness (r) and the flotation kinetics constant......

J. Cent. South Univ. (2012) 19: 238-243 DOI: 10.1007/s11771-012-0997-2 Flotation performances of polymorphic pyrrhotite HE Ming-fei(何名飞), QIN Wen-qing(覃文庆), LI Wei-zhong(黎维中), JIAO Fen(焦芬) School... of different crystalline structures of pyrrhotite (monoclinic and hexagonal) was studied. It is shown that the floatability of monoclinic and hexagonal has obvious difference, and that the flotation recovery......
system. The flotation kinetics was determined using a laboratory flotation cell. The results showed that the particles of rod mill products have higher roughness and elongation ratio and lower roundness than the parti-cles of ball mill products. The flotation kinetics constant of the particles increased with their surface roughness increasing. Particles with higher elongation and lower roundness......

slimes. Size analysis and flotation tests highlight that the MSA improved flotation recovery and kinetics of pyrite ore while causing some loss in selectivity, and in the presences of the polyacrylamide... flotation performances while intermediate or properly-sized particles produce high flotation kinetics and need low consumption of collectors. Sampling of most industrial flotation plants tabulated the similar......
surface area measurements and the analysis of adsorption kinetics, were introduced to analyze the adsorption mechanisms of the Pb2+ ions on bauxite flotation tailings.
