| Abstract Scope |
Heap leach residue from the Copperbelt province in Zambia contain about 0.6 % total copper. Copper is present in both sulphide and oxide minerals. The main gangue constituents in the feedstock are quartz and K-feldspar. The copper sulphide minerals in the feedstock are tarnished thereby making flotation not easy. Owing to the high demand of copper worldwide, this research focuses on extraction of copper from the heap residue. Copper was recovered as a concentrate via froth flotation. Copper was concebtrated from a feed grade of 0,38 % TCu into a concentrate of 32.01 weight. The final tailings consist mainly of quartz and K-feldspar which further be processed for the extraction of aluminum and potassium thereby leaving only quartz. |
