Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …
The global decrease in ore mineral grades and increase in ore mineralogical complexity has triggered the modern mining industry and research communities to search for efficient methods of processing ores which were initially considered uneconomic [1, 2].Gold-bearing copper minerals are common occurrences in many gold deposits and are generally …

Recent focus on hydrometallurgical methods for non-sulfide copper ores prompted a study on leaching a copper oxide ore containing 2.22% Cu, 44.9% SiO2, 6.94% Al, 6.61% Fe, 6.25% Mg, 3.67% Ca, and 1.7% Na with H2SO4 for gaining insight into the behavior of impurities in the leaching process. The effects of leaching time (30–180 min), acid concentration (0.25–2 …

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

The continuous development of the global economy has resulted in a high demand for copper production and high copper consumption [1], [2], and exploitation and effective use of copper oxide mineral resources have attracted attention [3].Copper oxide deposits evolve from shallow copper sulfide deposits after long-term oxidation, and they are widely and abundantly …
A dithiophosphate collector at an alkaline pH must be used (controlled by lime or soda ash if the pyrite content in the ore is low). Oxide copper–gold ores: The presence of clay minerals prevents flotation of these ores. Ester-modified xanthates have been used, with some success, to treat gold-containing oxide copper ores, using a ...
Hydrothermal iron oxide-copper-gold (IOCG) ore deposits are globally important sources of Cu and Au. IOCG systems show many common features, but also considerable diversity in terms of geological setting, mineralization style and ore fluid characteristics. The key factors that control ore formation are controversially debated and no general ore ...
