Heap leaching is a simple means of recovering copper from oxide and oxidesulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption.
Box–Behnken design was used to determine significant factors that affect the grinding of some copper sulphide ores and to develop quadratic mathematical model for the optimization of the process. The second purpose of this research was to investigate the effect of increasing feed size on the grinding modeling process of some copper sulphide ores.
Crushing and Grinding You will note that the Oracle Ridge project has utilized a twostage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all 5 material for the cone mill with a screen in closed circuit. Normally a threestage crushing circuit would have been more conventional, but with the type of ...
Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 2 inches. The next step is to feed the crushed ore into a wet grinding process in tumbling mills.

Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise that integrated research, manufacture, sales and service . The company has multiple subsidiaries such as Mineral ...
Copper sulfides describe a family of chemical compounds and minerals with the formula CuS minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores.. Prominent copper sulfide minerals include Cu 2 S and CuS ().In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copperiron sulfides, are often referred ...

OK. stone crusher, rock crusher plant 70,000 tonnes of copper sulphide ore per day using Andesite Crushing Plant In Indonesia; Copper Ore ...
Mined sulfide ores contain pentlandite, pyrrhotite, chalcopyrite and gangue rock. A highgrade nickel concentrate is produced from these ores by the following mineralsprocessing techniques: (a) crushing and grinding the ores to liberate the nickel and cobalt .
Copper Sulfide Flotation Reagents. Lime is added to the Ball Mill by a Cone Type Dry Reagent Feeder. Other reagents, such as cyanide, xanthate, and a frother are fed and controlled by No. 12A Wet Reagent Feeders to the classifier and to the conditioner ead of flotation. ... Copper Ore Grinding. Porphyry copper ores usually are medium to ...
Copper Ore Grinding Machine. The content of copper ore flotation and ease of iron sulfide ore closely. According to the number of sulfide copper ore iron sulfide content divided into two categories, one is dense massive copper ore, one is disseminated copper ore. The former is characterized by a high content of pyrite ore, sometimes up to 80% ...
Autogenous grinding mills, particle size control cyclones, m 3 mechanical flotation cells, middlings regrind, cleaner flotation: Product: ... The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper.
Copper sulfide ores are typically the most profitable types of copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted ...
How Copper is obtained from Ores Copper. Copper is extracted from an ore through various methods, depending on the nature of the ore of which it is being extracted from For example, sulphide ores such as chalcopyrite (the commonest ore of copper) are converted to copper in a different way than those from silicate, carbonate or sulphate or...
Have you ever wondered just how sulfideore copper mines pollute their surrounding environments? It''s a good question, because in order to understand the environmental impacts to the Boundary Waters Canoe Area Wilderness and Voyageurs National Park, we must first understand all of the ways sulfideore copper mining can cause harm to the surrounding lakes, streams, wetlands and forests.
Precious metals can be found in ore deposits along with sulfur, and are known as sulfides. Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated ...
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 wit...
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold.
Even though these minerals occur in relatively small amounts they can often be economically recovered as byproducts for the expense of mining, crushing, and grinding is absorbed in recovery of the copper. A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper ...
The high dosage of reagents necessary for the flotation of Salobo''s ore is responsible for the high final copper recovery even for grinding conditions less adequate for flotation. Very high collector dosages are necessary to provide the adhesion of the oxidised copper sulphide particles to air bubbles.
Grinding the crushed ore in rotating tumbling mills (<100 μm diameter). ... (%) copper sulfide ores. New facilities started in 2006 are expected to produce 180,000 tons/year of copper using acid curing, agglomeration, and bioleaching followed by SEXEW. Spence.
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 environment. For example: FeO(s) + SiO 2 (s)→ 2 (slag) This is .
