The Extraction of Copper - Chemistry LibreTexts

Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper(II) sulfate solution.

12.3 Primary Copper Smelting

iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte.

Extraction Of Copper | Mining, Concentration, Smelting ...

This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper; 98 99.5 % pure.

Smelting - Defintiion and Process and Roasting | Smelting Furnace

Smelting is the opposite of an oxidizing reaction to roasting. Process of Smelting. We use a reverberatory furnace in the industrial smelting of copper. Also, we pour concentrated ore and a liquid, normally calcareous, into the rim, and molten matte a mixture of copper, steel, and sulfur and pull out the slag from the bottom.

SMELTING OF COPPER SULPHIDE CONCENTRATES WITH FERROUS ...

The matte is discharged from the smelting furnace and then it is leached with aqueous sulfuric acid to dissolve iron and nickel as sulfates while leaving copper, lead and zinc sulfides for subsequent treatment. Ferrous sulfate is recovered from the solution by crystallization with copper sulfide, dehydrated and returned to the smelting furnace.

purification of copper by electrolysis metal extraction ...

Copper sulfide ores can be rapidly roasted in heated air enriched with oxygen to form impure copper and this extraction process is called 'flash smelting'. Nasty sulphur dioxide gas is formed, this must be collected to avoid pollution and can be used to make sulphuric acid to help the economy of the process.

Oxidation Potentials in Matte Smelting of Copper and Nickel

The current article extends the analysis to the smelting of copper and nickel/copper sulfide concentrates to produce mattes of the type Cu(Ni)FeS(O) and iron silicate slags, FeOxSiO2-with ...

Copper Smelting Process - Furnaces Used, By-Products, and ...

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...

Experimental and simulation studies of metal sulfide ...

Sulfide precipitation method has been widely used in the removal of arsenic and heavy metals from copper smelting waste acid. Nevertheless, tiny metal sulfide particles are generated during the process, making it difficult to achieve solid-liquid separation as well as solid-solid separation.

At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite - CuFeS 2. From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.

DIRECT REDUCTION SMELTING OF COPPER OXIDE ORE Part 1 ...

During smelting, copper will be extracted from the malachite ore. The efficiency of our smelting process will be determined by calculating the copper yield: the percent of copper in the ore that was extracted by the smelt. Before coming to class, calculate the amount of copper in each crucible charge.

Copper Smelter - Elmhurst University

At the same time some of the sulfide ions reduce the copper (I) ions to impure blister copper metal. A final heating in an anode furnace is used to burn off the remaining oxygen. An interesting aside is that for every ton of copper produced, 1.5 tons of slag and 2 tons of sulfur dioxide are also produced as waste products.

Smelting and Roasting Ores to recover gold, silver and other ...

The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix.

Copper Smelting Chemistry Tutorial - AUS-e-TUTE

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...
