· The nature of the ore deposits is extremely varied, comprising as it does primary and enriched copper and ironcopper sulphides ( chalcocite, chalcopyrite and bornite), fahlores ( polymetallic copper sulphides such as tetrahedrite and tennantite, which may be naturally rich in arsenic and antimony), and galena (lead sulphide), the ...
· The keen noses of sniffer dogs are proving so successful at loing ore that even the mining giants are sitting up and taking notice. Berenice Baker talks to Peter Bergman, geologist and CEO of the Swedish company OreDog, about his plans to turn the canine skills into a multimillion dollar global industry providing exploration services for the mining industry while .
SummaryBanded sulphide ores of the McArthur River type are characterized by large numbers of conformable, monomineralic sulphide bands. These appear to have formed prior to consolidation of the host sediments. This paper describes a series of laboratory experiments designed to test the possibility that the bands could have been generated by the migration of .
Answer (1 of 8): This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by .
The pillow lavas of the Semail ophiolite complex of northern Oman contain at least three exploitable massive sulphide deposits. These deposits at Lasail (8 000 000 t), Bayda (750 000 t) and Aarja (3 000 000 t) are dominated by pyrite, but also contain chalcopyrite and sphalerite with minor marcasite and pyrrhotite. They overlie quartzsulphidechlorite stockwork zones.

In contrast with its sulphide and carbonate, it is easier to obtain a metal from its oxide because when we extract metal from its respective ore, we have to conduct calcination or roasting steps in which metal carbonates and sulphides are converted into metal oxides.. Like their oxides, metals such as zinc, iron and copper are present in ores.
Copper Sulphide Ore Flotation Processing Plant Overview Copper Ore Flotation Processing Plant is mainly composed of jaw crusher, ball mill, spiral classifier, magnetic separator, flotation machine, ore concentrator and dryer machine combining with ore feeder, bucket elevator and belt conveyor which formed a complete ore beneficiation production line.
Polymetallic massive sulphide deposits are most commonly formed along tectonic plate boundaries and volcanic provinces in water depths from <500 to 5000m. Seawater seeps into the volcanic rock making up the seafloor through cracks and fissures. As this fluid becomes heated it circulates through the subseafloor, dissolving metals and other ...

metcon laboratories 21 report m1499 kay tanda sulphide ore Cyanide consumption did not decrease as the initial cyanide consumption decreased, but reducing the initial cyanide concentration from % to % appeared to have no effect on the gold residue grade, since the residue grades for tests KS9 and KS12 were essentially the same.
Complex sulphide ore samples were obtained from the Moinho deposit (Aljustrel mine), which is a volcanic massive sulphide complex ore found in southern Portugal. 760 R. Sousa, A. Futuro, C. Setas Pires, M. Machado Leite The materials were collected after the first fragmentation step of Aljustrel plant, and then crushed, homogenized and divided ...
As there are few sites processing such ore types, limited studies into the processing of copper and cobalt sulphide minerals exist . Within these deposits, carrollite (Cu 2 CoS 4) is the main cobaltbearing mineral in the sulphide ore and common copper sulphide minerals are bornite (Cu 5 FeS 4), chalcopyrite (CuFeS 2) and chalcocite (Cu 2 S).
In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.
Key words: sulphidebarite ore, high pressure leaching, ferric chloride Introduction Nonferrous metals and iron usually appears in a form of sulphide complex ores. The large deposits of complex ores may contain chalcopyrite, sphalerite, galena and pyrite in disseminated form with complex mineralogical composition and fine grained structures.
be~ore. the movement had ceased. Gossan is the name applied to the weathering product of the sulphide ore. In this region, the weathering pro duct of the ore body varies from the pure gossan, which is a porous brown material consisting of nearly pure limonite, a schistose gossan, limonitic schist, and iron stained
The sulphide ores are represented by disseminated, breccia and massive ore types. The disseminated ore is dominant and occurs in the lower and middle portions of the peridotite zone composed of dunite, wehrlite and serpentinite. The thickness of the orebodies ranges from 5 m to 270 m, and the sulphide content increases downward
the ore with the time of exploitation at the RTB mines [9] Oxide copper ore, mixed oxidesulphide ores and lowgrade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper can be acid, base, or salt solutions. Of all of
The ore treated in example I was a coppernickel sulphide ore containing an estimated average 40 percent of talcosetype minerals. The sample contained percent nickel in the form of pentlandite and percent copper in the form of chalcopyrite. The ore was ground in a laboratory rod mill at 60 percent solids to a fineness of about 95 ...
ores, the flotation and carboninleach processing method can treat both oxide and sulphide ores with better efficiency and has higher recovery rate. Wilton engaged Yantai Jinyuan Mining Machinery Co.

The average massive sulphide camp in Canada has about 9 deposits, but ranges from four (Manitowadge) to 21 (Noranda), However, an individual deposit may consist of a number of closely associated, discrete lenses ranging from several thousand to several million tons in size (ea. Millenbach Mine was 16 geologically discrete ore lenses).
Only sulphide ores are concentrated by the froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence, we can conclude that the correct answer to this question is option A.
Sulphide ores such as chalcopyrite are converted to copper by a different method from silie, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be ...
The process in which the sulphide ores of less electropositive metals like copper, lead, etc. are heated in air to convert the ore to oxide or sulphate is known as selfreduction. The selfreduction of sulphide ore occurs during the process of roasting. The roasting of ore involves gassolid reactions at higher temperatures.

The oxidation mechanism of sulfides is the key issue during the sulphidemetallurgy process. In this study, the phase transformation and element migration were clearly demonstrated by insitu laboratorybased Xray diffraction (XRD) and energydispersive Xray spectroscopy (EDS), respectively. The r .
Although the main cause of hydrometallurgical plant closures is the depletion of oxidized copper minerals reserves, the lack of new hydrometallurgy projects also contributes to these closures. One solution is to be able to process copper sulphide ores hydrometallurgically. However, it is widely known that sulphide copper ores—and chalcopyrite in particular—have very slow .

A process for the heap leaching of sulphide ores, the process characterised by the process steps of: (i) The agglomeration or wetting of an ore feed; (ii) Exposing the agglomerated or wetted ore to an inoculum containing one or more bacterial species capable of biooxidising sulphide minerals in that ore; (iii) Forming one or more heaps from the ore of step (ii); (iv) Dispersing .
· Model compound drop compositions coincide with the bulk ore 29, average oreforming brines 29 and many of the sulphide melt inclusions from Alumbrera 3, .
for extraction of copper the sulphide ore is concentrated by Copper Mining and Extraction Sulfide Ores The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environme
The sulphide ores have an average grade of wt.% Ni, and the bulk sulphide ores (recalculated to sulphide) have average PGE concentrations of ppb Os, ppb Ir, ppb Ru, ppb Rh, 31 ppb Pt, and 11 ppb Pd on average (Wei et al., 2013). This would equate to Mt of ore.
