The global demand andCharacterization growingFlotation consumptionMalachite ofAzurite metallicTenorite copperCopper lead not only to the exploitation of sulfurous mineralMineral deposits but also to the oxidized species, which leads to optimizing the concentration process. In this research, the cumulative flotationFlotation efficiency of a copperCopper mineralMineral containing azuriteAzurite, malachiteMalachite, and tenoriteTenorite is analyzed using the dodecyl amineDodecyl amine C12H27N (DDA) in proportions of 0.0125, 0.025, 0.05, 0.1, and 0.15 g/L and at a pH of 10, 11, and 12. The results indicate that the optimal flotationFlotation of copperCopper ore is at pH 12 with a DDA ratio of 0.05 g/L and a pulp potentialPulp potential of 45.6 mV. Higher proportions have no effect on improving the concentration with 89.2% w/w cumulative separationSeparation. With a less alkalineAlkaline flotationFlotation pH value, like 10.0, 83.9% w/w cumulative flotationFlotation is achieved using 0.025 g/L of DDA and a potential of +75.4 mV.
