    Size dependent gold deportment in the products of copper

    Commercial porphyry copper ores usually contain copper grades between 0.5% and 2%1. Minor amounts of gold are often present in these orebodies2. The concentration of gold in the majority of large scale copper/gold ores is low, typically around 1 2 g/t3,4. Flotation is the principal method of pre concentration for copper and gold5,6. Thus

    Flotation of copper is effected in the copper flotation circuit at a slightly acidic pulp pH of about 6.5 to 6.8, the pH being governed by the quantity of sulfur dioxide (SO 2) used during conditioning and aeration. A collector selective for copper in an acidic medium is employed, such as ethyl isopropyl thionocarbamate.
