Indium is produced exclusively as a by-product during the processing of the ores of other metals. Its main source material are sulfidic zinc ores, where it is mostly hosted by sphalerite. Minor amounts are probably also extracted from sulfidic copper ores.

Get PriceDemonstration of High Temperature Heap Bioleaching of Chalcopyrite Copper Ore It is a worldwide phenomenon that, as copper mines are getting deeper, more sulfidic ore is encountered. Furthermore, the average grade of reserves and unexploited deposits is dropping. Acid heap leaching has been widely used to extract copper from
[PDF]Get PriceUntil the early 1900s, much of the copper that came to market in North America was derived from native metal and so-called "oxide"ores. Sulfidic ores are the dominant source of copper today,as is the traditional (and costly) crush-ing-grinding-concentrating-smelting-electrorefining process of extracting metal from them.

Abstract—The roasting of copper ores belongs to the first roasting applications of sulfidic concentrates. Sulfatizing roasting has been used on an industrial scale for many decades. It is part of a well-proven extraction method that is particularly suitable for the copper and cobalt ores from the copper belt.
Get PriceOf the worldwide exploitable copper ores, about 90% are sulfidic, 9% are oxidic, and less than 1% are metallic copper ores. The principal sulfidic ores are chalcocite (Cu 2 S) and chalcopyrite (CuFeS 2; yellow copper ore), whereas cuprite is the major oxidic ore (Cu 2 O; red copper ore).
Get PriceChalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
Spent ore will always contain some portion of the target ore in very low concentrations, as well as other metals. Sulfide minerals are most commonly found in copper ore but are being found more frequently in gold as oxide deposits are mined out. Selenium, mercury, and arsenic are concerns in some spent gold ores.
Get PriceGenerally copper ores are classified into sulfidic and oxidic copper ores, whereas oxidic ores are a naturally oxidation product of sulfidic ores. Therefore usually oxidic and sulfidic copper ores are in adjoining sites. [1] Whereas sulfidic copper ores are mainly treated by pyrometallurgical processes
Get PriceCopper sulfide ores are typically the most profitable types of copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted ...
Get PriceCobalt occurs in various metallic-lustered ores, for example cobaltite (CoAsS), but is mainly produced as a by-product of copper and nickel mining.

Get PriceSulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.
