Abstract: Various factors that influence Au3+ extraction are studied. These factors include composition of the oil membranes and reactant in the internal phase, separating conditions and de emulsification method. Experimental results show that liquid surfactant membranes are suitable for extraction of gold from its solution of very low concentration (~2×10-6g/L). The extraction efficiency can reach 99% and even more.

Key words: liquid membrane, gold extraction, separation
