| Abstract Scope |
Copper in nature is generally extracted from sulfide minerals. However, an attractive source of this element is carbonates such as malachite, which contains 57.47% w/w copper in its structure. To increase its added value, a concentration process is carried out. This research work analyzes the flotation behavior of coarse particles of 170 mesh (90 microns) at pH 8.6 and 10.5 with potassium amyl xanthate (PAX) of a mineral that contains quartz as the majority phase, goethite, magnetite and malachite Cu₂(OH)₂CO₃ as minority phases, detected by X-ray diffraction. The results show 91.5% w/w copper flotation with a grade of 12.5% w/w at pH 8.6 with 0.5 g/L of PAX and a pulp potential (PP) of +152.8 mV; Higher pH does not improve the concentration, obtaining 87.2% w/w with a law of 14.13% w/w at pH 10.5 and PP of +72 mV. |
