Abstract:Extraction of copper from bacterial leach solution using Lix984 had been perform ed. It was found that the main factors influencing extraction yield of copper are the phase ratio and the concentration of extractant, following the pH of solution and extraction time and the order of factors influencing the separation rate is the pH of solution, the concentration of extractant, the extraction time and the phase ratio. The best conditions obtained by the orthogonal tests are as follows: the extractant concentration 4%, extraction time 3min, phase ratio 1:1, pH of solution 2.

 

Key words: solvent extraction; bacterial leach solution; copper
