Porphyry gold-copper ore is a type of ore that is often associated with large-scale, low-grade deposits. It is characterized by the presence of copper minerals, such as chalcopyrite, bornite, or chalcocite, as well as gold minerals, such as pyrite or native gold. ... The ore is crushed and then mixed with a cyanide solution, which dissolves the ...

IOCG Iron Oxide Copper Gold Ore Deposits goes with porphyries as they are also loosely associated with a large felsic intrusions and form at moderate depths, unlike the dominantly tertiary porphyries IOCG's tend to be much older and are generally protoizoic in age from 1.1 to 1.8 billion years ago.
This project is a strategic asset of PT Merdeka Copper Gold Tbk, MBM's parent company. The AIM project, located at IMIP, is designed to process waste ore from the Wetar Copper Mine into sulfuric acid, saturated steam, iron ore pellets, copper sponge, copper cathode, lead-zinc hydroxide, dore gold and silver.
The system was designed with the following objectives (Beaumont, 2016): Separating oxide ore from sulphide ore and categorizing anything that was not sulphide or oxide as mixed float ore Applying a set of cut-off grades to categorize waste, marginal grade, low grade, and high grade for both sulphide ore and oxide ore Improving the 'quality ...
of copper and 160 000 ounces of gold. Ore mined from the epigenetic vein-hosted deposit is classified into three ore types based on the extent of oxidation and supergene enrichment. Sulphide, oxide, and mixed ore are fed to separate mineral processing circuits tailored for recovery of the dominant copper minerals in each. After comminution to a ...
The global gold ore grade has been decreasing, and the mineralogy is now more diverse and complex. This has necessitated the utilization of low-grade ores previously not used. During the cyanidation process of such ores, copper cyanide complexes form that are competitively adsorbed with gold onto activated carbon. Therefore, to decrease the amount of …

The objective of this study was to assess the effect of lime and soda ash as pH modifiers on the flotation of a copper-gold ore mixed with kaolinite at different concentrations. For the flotation ...
A mixed culture of acidophilic microorganisms was used as an inoculum. Cu and Ni extraction depended on temperature, and at 45 °C, copper and nickel recovery was the highest, being 2.1 and 1.8 ...
The ammonia–cyanide leach system was first patented over 100 years ago and stands out as a unique method of selectively leaching up to 90% Au and <1% Cu from oxidised copper–gold ores using <10% NaCN used in conventional cyanidation processes.However, the system has proved to be difficult to control and predict performance with different ores due to a …
They show that different copper minerals can be present in a gold ore and its dissolution in cyanide can reach values higher than 90% depending on operational conditions and copper mineralogy. For instance, Table 1 shows typical values reported in literature (Shantz and Reich, 1978; Sceresini, 2005; Sceresini and Breuer, 2016) for copper ...
Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations. The production of a …

I'm working on an ore that has been mixed 4:1 with copper and then melted in a plasma furnace. The result is a copper shot with about 20% iron mixed within. We sent 1 Kilo to Arch enterprise and the results tested well for Ag,Au,Pd. Jim Lightsey the refiner at Arch said he was digesting the copper shot with 12.5% cold nitric acid.
Fig. 11 shows a comparison of the conventional and the FLOT-ART based advanced flotation process for a low-grade porphyry copper–gold ore using site-based brackish water. The conventional process resulted in a lower copper and gold recoveries, which was attributed to a pH buffering effect leading to very high lime consumption while attempting ...
The Kansanshi Mine (First Quantum Minerals) treats a mixed oxide/sulphide copper-gold vein deposit with very variable mineralization. All the copper minerals constituting the alteration
A material type ore classification system called 'Mat-Type was used to classify the various ore types based on a number of control parameters that would manage ore quality and ensure efficient and economic recovery of copper and gold. Ore containing mineral assemblages considered to be of 'poor quality' were directed to long-term stockpiles ...
In treating copper–gold ores, a sufficient free cyanide concentration is typically maintained to encourage the selective adsorption of gold over copper onto carbon (other than …
Economic copper and gold mineralisation occurs at the Kansanshi mine in three ore types – primary sulphide, mixed supergene, and oxide. ... Sulphide ore is treated via crushing, milling, and flotation to produce copper concentrate, whilst mixed ore is treated through a similar circuit. A high-pressure leach (HPL) facility treats a portion of ...
This research introduces a leaching approach to extract gold, silver and copper from gold-copper ores and concentrates using a synergistic lixiviant leaching process using glycine …
A decrease in concentrate grade was the main negative effect in the flotation of the copper–gold ore mixed with kaolinite with the overall flotation recovery not affected. Introduction. Kaolinite is a common clay mineral, generally considered to be in the colloidal size range, present in problematic ores in mineral processing (Bergaya and ...
The resulting metal fraction contains 84 wt% and 0.05 wt% copper and gold, respectively, and was oxidatively leached in two stages to initially separate copper and gold. Single copper and gold solutions are then obtained by solvent extraction purification processes using the well-exploited industrial extractant ACORGA M5640 for copper and the ...
A free milling gold ore, which contains 0.4% copper as chalcopyrite, was treated with cyanide. In the pre-leaching, the kinetics of oxidation of soluble sulphides are not an accurate indication ...
The copper- and gold-rich part of the Laurinoja ore body at Hannukainen contains an average grade of 0.50 wt% Cu and 0.39 ppm Au (based on the estimation of the Laurinoja high-grade Cu ore body, above a 0.25 wt% Cu cutoff; SRK, 2014).
