The Effect of Aromatic Content in Diluent on Copper Solvent Extraction Process

Petroleum combinations of diluents such as aromatic, aliphatic and naphthenic hydrocarbonsform a big part of solvent [1].An increase in polarity or dielectric constant of the diluentcaused a reduction in effectiveness of extraction [2]. To achieve good kinetics, aliphaticdiluents should be employed, but these diluents should contain a certain percentage ofaromatic in order to limit the extractant soluble losses to the aqueous phase [3].Extractionperformance with increasing electron donor diluents will decrease extremely[4,5]. In thisresearch the effect of aromatic content in diluents on copper extraction and strip was studied.
