At processing of polymetallic raw materials formation of sewage and industrial solutions, containing heavy nonferrous metals, particularly - zinc and such anions, as hydroxyl - and sulphate-ion is possible. The most effective ways of extraction and concentration of metals are ion exchange methods which concerns also liquid extraction. Here have been studied extraction properties of a phenolic type reagent on the NBEA-2 basis in relation to ions of zinc in the presence of specified anions. Semiempirical way of Mallyken method PM3 (Parameterised Model 3) with use of software product (software) HyperChem Release 8.0.4 (Hypercube Inc.) were made calculations of enthalpy formation and NBEA-2 complexe dissociations with hydroxyl - and the sulphate-ions which formation is possible at realization of zinc extraction process from aqueous alkaline and sulphatic industrial solutions.
