In present work, low content gold in copper ores was determined by using enrichment method. Complexing polymer sorbent (polystyrene-azo-thiazandithion-2,4) was used to increase the gold content for analysis of waste copper, copper ore and copper concentrate to upgrade the methodology. The optimum conditions of the volume capacity, pH, temperature, and time dependence enrichment of gold content were examined to increase analysis efficiency by using treatment of complexing polymer sorbent. The chemical interactions and molecular structure of PSTDT with gold were successfully determined using by FT-IR and theoretical calculations.
