Abstract

In the present study, the COPPER ANODE SLIME was leached in chloride media. Then, pregnant leach solution (PLS) was purified using SOLVENT EXTRACTION method and OCTANOL-kerosene solution. HAuCl4.2L was determined as the extracted macromolecule, and separation of impurities, such as copper, iron and selenium was done in the presence of GOLD. McCabe-Thiele diagram of Au–HCl (3 M)– OCTANOL (40% n/n) in O/A=3/4 showed that Au concentration in aqueous phase decreased from the initial value of 200 to 7 mg/L, after 5 stages. Ammonia solution was proposed as the stripper and McCabe-Thiele diagram was presented to obtain the number of GOLD STRIPPING steps by ammonia solution.
