    Please refer to this site first: http://home.att.net/~cat6a/metals-IX.htm

    I quote now, from http://www.citycollegiate.com/IX_copper.htm

    "Finely divided CuFeS2 is concentrated by "Froth-floatation method". Crushed ore is suspended in water containing pine oil. A blast of air is passed through the suspension. The particles of ore get wetted by oil and floats as a froth which is skimmed. The gangue sink to the bottom."

    And as far as I can recall, I never encountered an addition of nitric acid (or for that matter any acid) to the froth floatation mixture (containing pine oil and the crushed ore suspended in water).

    Please clarify...
