20% of world copper production is produced by this route and undoubtedly, it will increase steadily in the future.2) Hence, some new types of copper ores have to be considered to meet with the growth of world demand for copper. The iron-oxide hosted copper-gold (IOCG) ore,3,4) discov-ered in the giant Olympic Dam deposit in Australia firstly, is
Chapter 6 Copper Production Technology ... Spain, made the early advances in copper explo-ration and mining methods. For example, the Ro-mans found nearly 100 lens-shaped ore bodies in the Rio Tinto copper district. Modern geologists ... of iron to produce iron oxide removed in .
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.. Now in the first Exploration Geology Course I discussed how because our current mining technology all the metals that we use ...
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
method. Successful exploration for deeper Iron Oxide Copper-Gold (IOCG) deposits below the regolith cover depends on the understanding of the location and geometry of the controlling structures of the deposits. In the past, traditional methods were routinely used to remotely sense these deposits. These methods though apparently

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 – .
Types of copper ore: Sulfides. Different methods are used to process copper sulfide ores depending on the concentration of copper within the ore — higher-concentrated ores can be separated via ...
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
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 .
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 ...
Large, well-defined polymetallic deposit. NICO is an iron-oxide-copper-gold (IOCG)-type deposit which include world class analogues including Olympic Dam in Australia, Salobo and Sossego in Brazil ...
Iron oxide-copper-gold (IOCG) deposits can be identified quite successfully using the gravity survey method. These deposits give a strong positive gravity anomaly due to the abundance of hematite, an iron oxide mineral, which is much denser than the surrounding non-mineralised rock.

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
