The mine is a joint venture between BHPBilliton (%), Rio Tinto (30%), a Japanese consortium (10%) and the International Finance Corporation (%).
Answer (1 of 3): Hari om, you are asking a question as to : " How is copper obtained from its sulphide ore? What is the equation of this reaction?". Hari om. Hari om. ANSWER :[ Excerpts] COPPER MINING AND EXTRACTION: SULFIDE ORES : It's hard to imagine a world without copper. We rely on copper...
Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of. these base metal sulphide minerals is predominantl y through the froth flotation ...
FreeMilling Gold Gold ore is considered freemilling when over 90% of the gold can be recovered by a conventional gravitycyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of freemilling gold ores include quartzveined deposits and oxidized ores. SulfideAssociated Gold
Blasted ore from the open pit that is directed to the mill undergoes primary, secondary, and tertiary crushing to reduce the ore size, increasing the surface area to facilitate the release of minerals. The crushed ore is fed to the concentrator where it is mixed with water in .
proportions of sulphide and oxide copper minerals, the ore is classified into three distinct egories: sulphide, mixed, and oxide ores. As such, three separate processing circuits are used to mill the ore down to a standard targeted grind size of 80% passing 150 μm before froth flotation and leaching. A lot of research and development has
· The ore has a 5 to 10 percent sulfide content, so I expect about 10 to 20 pounds of sulfide concentrate. Dealing with 10 to 20 pounds is a lot easier than 200 pounds. There will be some loss of values in this operation but I accept this because although the method is less than optimal, it's the best I can put together.
milling of the underlying copper sulfide mineralogy 2) The increase in penalty elements in some ore bodies – the principal penalty element being found today is arsenic which is fixed through pressure oxidation, but other elements are sometimes found, depending on the ore body, including bismuth, etc.

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 NickelCopper Sulfide Deposits in the Lake Superior Region.
· Copper sulfide ores are typically the most profitable copper ore type to mine. That is because they have high copper content, and the copper .
· Massive sulfide deposits of the Vermont copper belt yielded 4 Mt of ore during intermittent production from 1793 to 1958. The deposits consist of stratabound and generally stratiform pyrrhotite, chalcopyrite, and minor sphalerite and pyrite within metasedimentary and minor mafic metavolcanic rocks of Silurian to Early Devonian age.
sulfide ores an overview | ScienceDirect Topics. Copper processing is a complied process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called hodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and ...
Mineralogical analyses were carried out on both ore type composites. The expected average ... The high throughput ore B comprise predominantly of pyrite and small copper sulphide minerals as the main gold carriers with quartz, dolomite, ... determining the mill sizes and power for the ore grinding circuits.

· 01 One Stage GrindingFlotation Process. Grinding fineness is an important factor affecting the beneficiation index of copper sulfide the grinding particle size is too fine, the ore is easy to be overcrushed, which affects the separation process and increases the grinding the grinding particle size is too coarse, the copper minerals will not be effectively dissociated, which ...
for copper sulfide ores is around 4. For example, if you had a marginal mineral with a head grade in the coarse fraction of % Cu, the coarse preconcentrate would have a grade of around 1% Cu. This preconcentrate will need to be dewatered, and then go to coarse regrinding for

The ball mills will be in a closed circuit with hydrocyclone clusters. The SAG feed conveyor will feed ore to the SAG mill, m diameter by m long, flangetoflange (40 ft diameter by 25 ft long, flangetoflange) driven by a 24 MW gearless drive. The SAG mill product will discharge to a trommel and then to a pebble wash screen.
· Instant flotaion process, copper staged preferential flotation process and electrochemial flotation process are three widely used ways to extract copper sulphide ore. We can choose the most suitable process according to the characteristics of our copper ore.
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
