Thermodynamics of removing impurities during copper smelting

摘要: AbstractThe removal of impurities from matte and copper during smelting is discussed thermodynamically. Two mechanisms are considered: oxidation followed by slagging; volatilization. In matte, most the undesirable such as lead, antimony, bismuth arsenic not removed oxidation, but rather When white metal metallic in coexistence, these distributed mainly into phase, which their difficult. Elimination various elements blister discussed, behaviour sulphur oxygen analyzed Resume Les auteurs se servent de l' energetique pour expliquer elimination d'impurites la et du cuivre au cours do smeltage. Ils considerent deux mecanismes d' elimination: l'oxydation suiviede solubilisation des oxydes dans scorie,et volatilisation. Dans le cas les impurites indesirees telles que plomb, l'antimoine, ...
