  • Leaching of Copper Sulphides - SAIMM · Fichier PDF

    Ferric sulphate leaching and copper chloride leaching are carried out at atmospheric pressure while total pressure oxidation takes place at elevated pressures. Hydrometallurgical processing routes may be sought for a number of reasons as alternatives to more conventional pyrometallurgical processing (Dreisinger, 2006).

  • Copper Leaching Method - Metallurgist & Mineral .Traduire cette page

    Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per pound.

  • NEW COPPER LEACH TECHNOLOGY | .Traduire cette page

    The Galvanox technology is a novel atmospheric leaching process which offers several potential advantages over existing copper-leach processes for primary copper sulphides. As it is selective for the primary sulphide mineral chalcopyrite over pyrite, it is applicable to low grade or bulk concentrates.

  • High-purity copper recycled from smelter dust by .

    Smelter dust from copper extraction plants contains copper (Cu), which is both an economic loss and a pollution issue. There is therefore a need for techniques to recover Cu from ultrafine dust. Here we tested sulfation roasting, water leaching and electrorefining to recover Cu. We studied this process by thermochemical simulation and thermogravimetry to optimize sulfation roasting parameters ...
