Copper Ore Types: Sulfides vs. Oxides An Investor's

There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, but they are processed in different ways.

Copper Ore Types: Sulfides versus Oxides Nasdaq

Apr 23, 2011 Copper oxide ores. Copper oxide ores are not as attractive of an exploration target as the copper sulfide ore types due to their lower grade, however low-grade copper oxide deposits can be

Oxidation of Copper Sulfides and Secondary Sulfide

Leached capping over disseminated (porphyry copper) deposits is more favorable than gossan from massive sulfide deposits for the interpretation of leached outcrops. Subsidence features related to collapse of gossan derived from massive sulfide ore bodies may provide excellent guides for exploration.

Differences Between Sulfides And Oxides Difference Between

There are different types of sulfide minerals. Selenides, tellurides and antimonides are just a few of the classes that sulfide minerals have. Second, sulfides differ from oxides through their composition. Oxides are those minerals that contain oxide anions, or oxygen, with ice and quartz being the exceptions.

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

In order for an oxidized deposit to be formed, an original sulphide ore body must be present. The sulphide ore body may be formed by cold alkaline oxidizing seawater migrating through sediment and other rock beneath the sea.

Iron oxide copper gold ore deposits Wikipedia

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging

being oxidized, including the formation of exotic copper deposits, and (2) through in situ oxidation of a copper-bearing sulfide resource. Importantly, the first type of copper oxide system requires copper transportation from a source region, but the protore does not need to have high copper content if leaching and precipitation are efficient.

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

A review of the beneficiation of copper-cobalt-bearing

Nov 01, 2019 The H 2 SO 4 leaching efficiency of oxide-sulphide Cu ores rarely exceeds 75%, mainly due to the difficulty of dissolving the sulphides in sulphuric acid at atmospheric pressure. This means that the leach residues will contain sulphides that would trigger acid mine drainage (AMD) and a significant amount of recoverable metals.
