R. Dunne, in Gold Ore Processing (Second Edition), 2016 7.5 Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997).This combination gives satisfactory results in respect of copper concentrate grade and

LEACHING OF LOW-GRADE COPPER ORES: A CASE

2017-6-9  The basic copper carbonate minerals, which are easily leached with the solution of sulphuric acid are: azurite, malachite and chrysocolla. Cuprite, tenorite and elemental copper, which are also found in ore deposits of copper, can be converted into a soluble form by leaching, where the chemistry of the process is simple.

Mineral Reference

1997-3-10  Comments: Cuprite, copper oxide is a common and widespread ore mineral formed by oxidation of sulfide minerals in the upper zones of copper veins. It forms octahedral crystals (ISOMETRIC SYSTEM) and granular masses that are various shades of red; parallel, elongated ruby -red needles are called chalcotrichite, and brick red earthy masses are

Gold in Minerals and the Composition of Native Gold

2012-4-17  GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S. JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu­ tions with silver, copper, nickel, palladium, and

Ore minerals

Copper Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and brochantite.
