Study on the grinding kinetics of copper tailing powder

May 01, 2018In addition, the grinding process can not only levigate copper tailing powder, but also narrow down and homogenize the Particle Size Distribution (PSD). The Equivalent Particle Size (EPS) shows a negative while the Specific Surface Area (SSA) shows a positive linear correlation to the double logarithm of grinding time.

Increasing the grind size for effective liberation and

Aug 01, 2016Grind size can be increased by approximately 30–50 μm. • Copper recovery can be improved by approximately 1%. • Small reductions in competency can still yield improved liberation and flotation. • Intimate association of copper and iron sulphides helps liberation enhancement. Abstract

Study of Flotation Parameters for Copper Recovery from

It was shown that maximum copper recovery of 95,3% was obtained at pH 12.3 by lime.It was suggested to grind up to 65.72% of -0.074 mm to achieve the optimum recovery of copper and high grade of arsenic in concentrate. Overgrinding led to desliming and more loss of As in tailings.

Grinding and Polishing Guide Buehler

Hack-sawed, bandsawed, or other rough surfaces usually require abrasive grit sizes in the range of 120-180 grit [P120-P180}. The abrasive used for each succeeding grinding operation should be one or two grit sizes smaller than that used in the preceding step.

Study on the grinding kinetics of copper tailing powder

May 01, 2018The particle size of copper tailing powder decreases and the particle distribution narrows with the grinding time. The maximal particle size of all ground samples is no larger than 135 μm, and particle size ground for 90 min is <14 μm.
