Sedimentation Effects of Adding Flocculants to Leached Slurries at Lab Scale in the “Comandante Ernesto Che Guevara” plant in Cuba

Abstract

The objective of this investigation was to evaluate the effects of adding PICIZ 7010, AN 910SH and Quimifloc N-30 flocculants to leached and magnetized slurries at lab scale. The evaluation was completed through the comparative method in accordance to the NRBI-579 Standard: Sedimentation Tests which use Talmage and Fitch method. The addition of Quimifloc N-30 flocculants to 6 g/t of reduced ore increased slurry density by 5,9 %, improved liquor clarification as result of a reduction of up to 75 % in suspended solids and slightly reduced the required unit area.
