  • Advanced Process Control of grinding & flotation in

    Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill loads, motor torque and power, plus pressures

  • Effect of Grinding Media on Galena Flotation

    Parallel tests performed with an active metal, magnesium, indicated that floatability was also affected by the presence of a surface coating involving lead species. Grinding with steel media adversely affects the flotation response of galena. Electrochemical measurements, flotation tests, and examinations were employed.
