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

By Eluberto Espinosa-Espinosa and Pedro E. Beyris-Mazar


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
