Here let''s understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known. These are somewhat the giants of the ore deposits world. As a mining interested learner, the geology of porphyry copper deposits is vital to your education.
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 % and 5% copper, with gold contents .
Dear Colleagues, The discovery of the Olympic Dam, and its definition as a new type of copper deposit with important resources and other commodities (Fe, Au, U) and Iron OxideCopperGold (IOCG) deposits, has caused great interest in formation processes and characteristic guidelines that are useful for their exploration.
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 ...
The Geochemical Database for Iron OxideCopperCobaltGoldRare Earth Element Deposits of Southeast Missouri (IOCGREE_GX) contains new geochemical data compilations for samples from IOCGREE type deposits in which each rock sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. IOCGREE_GX was created and .
The impure copper is then purified by electrolytic purification to % 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;
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. Process Description24
As a result, a high degree of gold adsorption onto the peptidefunctionalized surfaces was observed in the aqueous solution. ICPMS was used to measure the concentration of the iron oxide nanoparticles, the mined gold, and the leftover gold.
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.
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.
Smelting is a process of applying heat to ore in order to extract a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base 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.
No investigation on the usage of WV3 data for mapping iron oxide / hydroxide minerals, especially in the porphyry copper deposits has been published. We focus on evaluating the capability of WV3 VNIR data in mapping iron oxide / hydroxide minerals associated with the porphyry copper mineralization in Ardestan area, northeastern Isfahan, .
Aug 01, 2019· Textural and compositional data of magnetite from Igarapé Bahia, Alemao, Sossego, Salobo, and Candelaria iron oxide coppergold (IOCG) and El Romeral Kirunatype iron oxideapatite (IOA) deposits show that some magnetite grains display oscillatory zoning or have been reequilibrated by oxyexsolution, coupled dissolution and reprecipitation (CDR) reactions, and/or recrystallization.
Santo Domingo is part of the IronOxideCopperGold (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 – .
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.
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.

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.
