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 ranging

Kucing Liar is a large sedimenthosted CuAu mineralized system containing some 15Moz of gold and 5Mt of copper in ~500Mt of ore. It is situated in the Ertsberg Mining District in the Central Ranges of New Guinea, in the Indonesian province of West Papua. This study demonstrates that high sulphidation ore is continuous with typical porphyryskarn style chalcopyrite ore and that both have

#0183;#32;Depending on the distribution of gold and copper in the ore body, there may be the ability to selectively mine the deposit to produce one or more of the following feed streams: 1. Gold ore with low soluble copper (and thus amendable to direct cyanidation) 2. Copper ore. 3. Gold ore with high soluble copper

overprinted by sericitic alteration. Minor gold along with molybdenite, some copper, and basemetal skarn mineralization occurred during this early event. A second mineralization event, which accounts for the bulk of the gold in the deposit is characterized by advanced argillic alteration, free gold, and abundant pyrite in the
from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from coppercyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide''s fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

Thesis. Fulltext available. Jan 2019; The ore body is a complex coppergold porphyry deposit, comprising intermixed oxidized, transition and sulphidic gold and copperbearing ores.
The copper concentration was chosen based on the copper concentrations found in gold mining, which have high cyanidesoluble copper content in the ore [5,[24][25][26].

mining for copper, gold and iron ore continued into the first half of the 20th century. In the 1960s and 1970s Pacific Copper conducted exploration focused mainly on the copper in the skarns. During the 1980s, they were joined in JV by Homestake to explore for gold. Newcrest acquired the property in March 1991. Initial Newcrest involvement
refractory gold ore bearing organic carbon. 4. Bacterial Preoxidation The research of bacterial peroxidation is quite active. The technology started to process ores in the 1950 s, and at first leached to recovery copper from the lowgrade copper ore or marginal copper ore.
