Experimental research on extraction of copper from heap leaching solution of a low-grade oxide copper oxide ore
Different types of copper extractants were scrutinized during copper solvent extraction and stripping processes of an copper oxide ore's heap leaching solution.The isotherms equilibrium phase process isotherms and corresponding phase separation rates of three different types of copper extractants under cabinet temperature(25℃)were measured.McCabe-Thiele isothermal diagrams were generated,and the extraction efficiency,stripping efficiency,Cu and Fe exclusion rates and net copper transfer were calculated.The results show indicate that extractant A is the most suitable reagent,whose extraction efficiency is 99.3%,the stripping efficiency is 97%,the exclusion rate of copper and iron is 816 and net copper transfer is 2.68 g/L.
