The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.

Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour, our process allows ...

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

The present invention discloses a new process for leaching sulfide minerals consisting of leaching crushed ore in a vat reactor, wherein the leaching solution is fed with an ORP value close to the upper limit suitable for leaching and the exiting leaching solution leaves the reactor with an ORP above the lower limit suitable for leaching the ore.

The process according to claim 4, wherein said iron sulfide concentrate is roasted in the presence of excess oxygen to produce a calcine of iron oxide, wherein sponge iron is produced from said iron oxide, adapted for precipitating copper from the sulfur dioxide treated pregnant solution that has resulted from the leaching of the copper oxide ore.

The specific process for selecting copper ore depends mainly on the material composition, structure and copper occurrence state of the original copper ore. Generally speaking, copper ore can be divided into three categories: copper …

For copper sulfide ore, electrolysis is the final stage in the process of pyrometallurgy, in which anode copper slabs are hung in a large tank full of a copper-based electrolyte solution and an electric current is applied, resulting in the plating of copper onto 99.9% pure copper cathodes.

fides and copper sulfide for med copper sulfate, whereas iron sulfide converted mostly to hematite at 500˚C [9]. In the present work, a sulfation roasting-acid leaching process that associated pyrometallurgical and hydro-metallurgical methods has been used for the recovery of copper from a copper sulfide concentrate. The reactions

At present, the separation methods used for copper–cobalt sulfide ores include the following: Duan et al. improved the recovery rate of copper–sulfur minerals by changing the reagent system. Ba et al. [ 11 ] adjusted the process flow and used combined flotation–magnetic separation technology to recover cobalt minerals, which are difficult ...

Oxide–sulfide copper ore was sampled from the ore body Cerovo C1 (south deposit) and used in this study. The chemical composition of the ore sample is pre-sented in Table 1. From Table 1, it can be seen that the high copper concentration is in the sample, as well as the high copper oxide content, while the sulfide copper concentration is lower.

Separation of special copper ores such as those containing molybdenite or with high zinc or lead content (Canada) is also possible by flotation methods. Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching.

(k) Total smelter charge means the weight (dry basis) of all copper sulfide ore concentrates processed at a primary copper smelter, plus the weight of all other solid materials introduced into the roasters and smelting furnaces at a primary copper smelter, except calcine, over a one-month period.

The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. The presence of pyrites in many ore deposits, and its reaction with water and oxygen to form iron sulfate and sulfuric acid, creates an important source of acid.

amount of ore can be processed and the processes offer more safety and access for mine workers. 15 In open pit operations, the fist step is the removal of overburden and waste rock to 7 United States Geological Survey. 1998. Potential for new Nickel-Copper Sulfide Deposits in the Lake Superior Region.

copper sulphide leaching options as alternatives to the more conventional pyrometallurgical processing route of copper sulphides. Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching. The effect of mineralogy

The Escondida Sulphide Leach Project (SLP) has been designed to initially produce 180,000 tonnes-per-annum (tpa) of high quality copper cathode through a process of bacterially assisted leaching of low-grade ROM sulphide and oxide ore. The sulphide ore will be sourced from the existing Escondida pit and oxide and sulphide ore will be sourced from

Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained metal is then purified by electrolytic refining.

Types of copper ore: Sulfides. Different methods are used to process copper sulfide ores depending on the concentration of copper within the ore — …

The mixed-priority flotation process is suitable for the extraction of copper from dense massive sulfide ore and disseminated sulfide ore with a non-sulfide content of more than 10-15%. The process flow is shown in the figure below.

An improvement in the ferric chloride leach recovery of copper from its sulfide ores which comprises recovery of the copper from the leach solution after removal of sulfur by electrolysis rather than by conventional cementation with added iron.

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

LEACHING OF A ROASTED COPPER SULFIDE ORE Rosselle Kim P. Castillano, Wilfredo T. Gatdula Jr., Gin Derick L. Magno, Jhunalyn H. Parantar METE 157N: HYDROMETALLURGY LABORTORY ABSTRACT Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition.

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate ...

JX Nippon Mining and Metals Corporation has developed the JX Iodine Process, which is an innovative and patented copper-leaching process for low-grade primary sulfide ores. This process consists of the irrigation of ferric iron and a low concentration of iodide solutions.

The traditional route for extracting copper from sulfide ores is smelting. Yet there is a growing case for leaching sulfides from lower grade ore bodies and especially for those ore bodies containing problematic elements like arsenic, which make smelting less economical. Smelting is increasingly expensive because, in general, smelters require a ...

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the ...
