Treatment of Mixed Sulfide Oxide Ores of Copper
Beside the ores containing copper mainly as sulfide, with a small amount of oxidized copper, many of the large porphyry mines have oxide orebodies, in which the proportion of non-sulfide minerals is so high that present methods of treatment are inefficient. In some of the well-known orebodies in the Miami-Inspiration district the copper occurs about equally in sulfide and oxidized forms; and ...

Treatment options include bulk flotation of copperrich sulfide ores selective copper flotation acidic, alkaline or ferric ion leaching and ammonia preleaching of the ore prior to conventional cyanidation.
Novel treatment for mixed copper ores: Leaching …
The treatment begins with an acid leaching amidst a pH 1–2, followed by precipitation at pH 3–3.5, which is fixed with lime to avoid unnecessary iron consumption. Finally, the copper precipitate (like copper cement) and copper sulfides (without leaching) are floated in an acid medium at pH 4–4.5 . The economic and environmental concerns derive principally from the high temperatures required to leach …
