Santo Domingo is part of the Iron-Oxide-Copper-Gold (IOCG) belt in northern Chile. The IOCG belt stretches to about 1,200km and contains several copper deposits. The Santo Domingo mine is of the Punta del Cobre Formation and contains four deposits – .
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

Iron Oxide Copper Gold Deposits Processing Methods
The Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri (IOCG-REE_GX) contains new geochemical data compilations for samples from IOCG-REE type deposits in which each rock sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. IOCG-REE_GX was created and .
Jun 15, 2018· The ore is crushed and then concentrated by froth-floatation process. ... Cupride plus iron sulphide gives copper glance plus iron oxide. ... This method is used to get metal of high degree of ...
Copper Ore Types: Sulfides vs. Oxides. ... Read on for an overview of the types of copper oxide ores and copper sulfide ores, with a focus on how they're processed. ... Different methods are ...
hematite or magnetite (iron oxide) siderite (iron carbonate) stilpronmelane (iron, magnesium alumiosilicate) Banded iron formations are critical to our current economy as they are by far the biggest source of economic iron deposits. China and Australia are the world's largest iron producers, and both have enormous reserves of BIFs.
The occurrences of gold is encouraging and is in line with our belief that there is potential iron oxide copper gold (IOCG), Olympic Dam style mineralisation. Our strategy is different to that of the explorers in the 1960s, in that we are interested in the large scale copper oxide occurrences as well as deeper sulphide material.
The operation includes a fully integrated metallurgical complex with a grinding and concentrating circuit, a hydrometallurgical plant incorporating solvent extraction circuits for copper and uranium, a copper smelter, a copper refinery and a recovery circuit for precious metals.
The impure copper is then purified by electrolytic purification to 99.99% pure copper while the iron oxide is disposed of as slag. ... where copper deposits are not plentiful and tend to be small, there are 40 to 50 "mom & pop" leaching operations involving SX/EW. ... How Hydrometallurgy and the SX/EW Process Made Copper the "Green" Metal;
Figure 2.4.1: Diagrammatic sketch of the iron oxide-copper-gold mineral system illustrating the relative location of deposits types within the overall setting and the likely distribution of critical and other commodities within and around these deposit types. In the commodity lists, blue indicates critical commodities, underlined bold indicates ...
Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
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 .
The ore deposit at Grängesberg is of the apatite-iron oxide type and is considered by some to belong to the group of Iron-Oxide-Copper-Gold-deposits (IOCG, Corriveau 2007).
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, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower .
Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold. • The gold is present as native gold, electrum, and gold–bismuth–antimony–tellurium alloy. • The gold distribution is controlled by gold contents in host rocks and the efficiency of precipitation mechanism.
This paper provides an overview of the NICO deposit process development work throughout the past decade, with emphasis on the latest results on the recovery of cobalt. The results presented in the paper were produced . by an integrated pilot plant carried out in 2008. The NICO "IOCG" (iron oxide – copper - gold) type deposit is

We demonstrate the success of the method using magnetic and DC resistivity data from Cristalino iron oxide copper gold (IOCG) deposit, located in northern Brazil, which is covered by a thick soil ...
No investigation on the usage of WV-3 data for mapping iron oxide / hydroxide minerals, especially in the porphyry copper deposits has been published. We focus on evaluating the capability of WV-3 VNIR data in mapping iron oxide / hydroxide minerals associated with the porphyry copper mineralization in Ardestan area, northeastern Isfahan, .
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
A number of iron deposits near Kiruna in the Norrbotten region of northern Sweden are of the iron oxide apatite (IOA) type of deposits; also referred to as Kiruna-type deposits. They are commonly considered a subgroup or end-member of iron oxide copper gold (IOCG) deposits, containing no economic grades of copper or gold.
Aug 01, 2019· Textural and compositional data of magnetite from Igarapé Bahia, Alemao, Sossego, Salobo, and Candelaria iron oxide copper-gold (IOCG) and El Romeral Kiruna-type iron oxide-apatite (IOA) deposits show that some magnetite grains display oscillatory zoning or have been reequilibrated by oxy-exsolution, coupled dissolution and reprecipitation (CDR) reactions, and/or recrystallization.
