微细粒选钨尾砂伴生铜资源浮选动力学
Flotation Kinetics of Copper Resources Associated with Micro-fine Particle Tungsten Tailings
摘要
Abstract
The change rule of copper floating rate with time was investigated at the optimum reagent system(ester agent Z-200,combined xanthate collector iso-amyl+Y89 xanthate(9∶1)and foaming agent MIBC)obtained by the flotation test from a fine particle tungsten tailing from southern Jiangxi Province.Hyperbolic function,S curve function and negative exponential function were used for regression fitting calculation,three kinds of copper flotation kinetic models were derived,and four kinds of common kinetic models were fitted.The results show that the hyperbolic function regression calculation is close to the experimental results,and the error sum of squares is 1.380 0.The flotation process of copper conforms to the full mixed reaction kinetics,gas-liquid adsorption kinetics and second-order kinetics,and the fitting degree R2 is more than 0.99.关键词
