搅拌调浆对硫化铜镍矿物浮选的影响
Influence of mixing conditioning on flotation of copper-nickel sulfide ore
摘要
Abstract
Flotation test of copper-nickel sulfide and serpentine mixed ore after different kinds of mixing conditioning by agitator with four straight blades and agitator with four tilting blades were carried out, and the maximum recovery of flotation and flotation rate coefficient were obtained by nonlinear curve fitting and the mixing tank flow field parameters were gotten by CFD method. The influence of conditioning in the flotation of copper-nickel sulfide ore was studied by correlation analyzing. The results show that slurry shear stress produced by conditioning can reduce the heterogeneous coacervation between serpentine and copper-nickel sulfide ore. The shear stress and axial velocity of fluid can both affect copper nickel sulfide ore flotation recovery rate, and the conditioning equipment should adopt both straight blades and tilting blades type agitators to optimize the shear stress and axial velocity.关键词
