The formation of powder deposits that adhere loosely to the cathode is favored by low copper ion concentration in the electrolyte, high acid concentration and high cathode current density. The addition of colloids, such as glucose, results in the formation of a uniform copper deposit. The starting material is pure cathode copper.
Spatial analysis of mineral deposit distribution: A review of methods and implications for structural controls on iron oxidecoppergold mineralization in Carajás, Brazil
Australia (from 2012) indicates a significant opportunity for gold recovery from iron oxide coppergold (IOCG) deposits, which contain % of the inferred gold resources but only contribute % of gold production in Australia. In comparison, other (non IOCG) coppergold deposits in Australia

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 byproduct of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

The Mesozoic deposits in the Central Andes, especially represented by the dominant iron oxide coppergold (IOCG) mineralization in southern Peru and northern Chile coastal IOCG belt, has emerged as one of the major exploration targets in the Central Andes in the last two decades.
Iron oxidecoppergold potential of the southern Arunta Region Iron oxidecoppergold (IOCG) deposits are a diverse family of mineral deposits unified by a number of common geological features, including the presence of abundant iron oxides, extensive hydrothermal alteration and strong structural controls (Williams et al., 2005). As well as copper
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.

Copper oxide can be heated very strongly to make it decompose into Copper and Oxygen, but this procedure need high amount of heat. So, another efficient method used is, to react copper oxide with ...
Jan 14, 2019· Under electrical charge, copper ions migrate from the solution to copper starter cathodes that are made from high purity copper foil. Other elements that may be present in the solution, such as gold, silver, platinum, selenium, and tellurium, collect in the bottom of the tank as 'slimes' and can be recovered through further processing.
When this stuff touches a particle of gold which has it's own coat of iron or other metallic oxide or sulfide, it will immediately reduce that too, leaving only the fine powder metal that will wash away leaving a nice clean gold surface just waiting to be amalgamated by the mercury which is also present.
Mesozoic ore deposits are mostly polymetallic volcanogenic massive sulfide (VMS) and CrCuNi(PGE) deposits associated with oceanic ultramaficmafic complexes. Intrusion of plutons related to porphyry copper and magmatic hydrothermal iron oxide copper gold (MHIOCG) systems peaked in .
Dec 28, 2016· Abstract. The field radiometric and laboratory measurements were performed at the Sin Quyen copper deposit in North Vietnam. The field gammaray spectrometry indicated the concentration of uranium ranging from to 87 ppm, thorium from to ppm, and potassium from to %.
From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.

The Fe‐rich samples with abundant hematite are generally enriched in elements as Mn, Co, As, V and W. It is known that these elements are all detected in hematite as a principal mineral from iron oxide–copper–gold (IOCG) deposits (Carew, 2004). As suggested earlier, the quartz veins contain host rock residue as rutile.
