    How Hydrometallurgy and the SXEW Process Made Copper

    Beginning in the mid 1980s a new technology commonly known as the leach-solvent extraction-electrowinning process or SXEW Process was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today worldwide approximately 20 of all copper produced is produced by this is process.

    Therefore if the ore has 40 gt of cyanide-soluble copper then the minimum quantity of cyanide required for copper leaching is 0.1 kg NaCNt. If the quantity of copper extracted increases to 300 gt then the cyanide requirement increases to 0.7 kg NaCNt. Viewed another way since the 3 moles of cyanide that are complexed with each mole of .

    such as roasting pressure leaching or bacterial leaching. The adverse effect of graphitic carbon can also be overcome by roasting the ore or concentrate to burn off the carbon. All of these techniques are relatively expensive however so the economic cut-off gold grade for refractory ores is somewhat higher than non-refractory ores.

    Aug 22 2019 Among the gold resources the amount of low-grade oxidized ore occupies a certain proportion. It is not economical to use the cyanide method to extract gold and the heap leaching process has economic benefits. The heap leaching method actually deposits gold-bearing ore on an impervious site and is immersed and leached with a cyanide solution.
