LEACHING KINETICS OF CU, CO, ZN, PB AND FE FROM COPPER

The overall extraction was 46.4% Cu, 78.96% Fe, 85.66% Zn, 91.94%Pb and 95.29% Co, but there was no selectivity in the leaching process of this slag. Slag sample GCM2 had an amorphous phase content of 22%. Leaching of this type of slag produced results with a higher selectivity of Cu in comparison to all the other base metals.

Selective leaching of Pb, Cu, Ni and Zn from secondary

In this process, Cu, Zn and Ni leaching was insignificant. For the slag residue, HNO3 could not leach Pb (0.03% Pb leached), while Fe leaching was 19.8% due to a galvanic effect. However, Pb...

Selective leaching of Pb, Cu, Ni and Zn from secondary

At a higher temperature, Pb leaching was reduced due to PbSO 4 precipitation. In this process, Cu, Zn and Ni leaching was insignificant. For the slag residue, HNO 3 could not leach Pb (0.03% Pb leached), while Fe leaching was 19.8% due to a galvanic effect. However, Pb leaching of the slag was 82% in the presence of additional Fe (III).

TWO STAGE LEACHING PROCESS FOR Cu AND Zn RECOVERY

By chemical analyses of the bioleach solution, it was confirmed that the recovery of Cu, Zn and Fe on Day 9 was 70%, 55% and 23%, respectively, while at the end of the acid leaching step, the cumulative recoveries for Cu, Zn andFe was 75 %,60 35 respectively. The two-stage process did not produce higher Cu and Zn recoveries.

A two-step leaching method designed based on chemical

Using the two-step leaching method, 82.89% of Cd, 55.73% of Zn, 10.85% of Cu, and 0.25% of Pb were leached in the first step by 0.7 M HCl at a contact time of 240 min, and the leaching efficiencies for Cd, Zn, Cu, and Pb were elevated up to 99.76, 91.41, 71.85, and 94.06%, by subsequent treatment with 0.2 M EDTA at 480 min, respectively. Furthermore, HCl leaching induced fractional
