Flotation of metallic copper

Jun 15, 2018 Sulfide copper mineral, typically Chalcopyrite (CuFeS2), is one of the most common minerals for producing metallic copper via the pyrometallurgical process. Generally, flotation tailings are produced as a byproduct of flotation and still consist of un‒recovered copper

    Copper sulphate is a common flotation reagent for blende ores. Metallic iron is also present in the mill circuit and a reaction between the iron and the salt would be in accord with well known chemistry. The abundance of metallic iron in a flotation feed may be noted by the examination of any feed. It originates, first of all, in the mine, then the coarse crushing machines contribute their

    60 Centuries of Copper: The Flotation Process

    Sep 24, 2018 The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper
