copper ore reduction processing

Copper Ore Processing Methods. The four major steps in the production of marketablecopperare mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

Theprocessused to treat sulfidecopper oresbegins at the mine site, where thecopper-bearingminerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage ofcopper increasesas theoreis refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

After this stage theenriched orenow contains about 25%copperby mass and is calledcopper concentrate. It is valuable enough to ship to other plants and other countries forprocessing. For example China, Germany and Japan are majorcopper producersthat use concentrate from around the world.

Copper processing, the extraction ofcopperfrom itsoresand the preparation ofcopper metalor chemical compounds for use in various products. In its pure form or as an alloy,copper(Cu) is one of the most important metals in society.

Copper Mining&Extraction Process FlowChart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of theCopper MiningandCopper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphidecopper mineral(ore).

TheProcessThe concentratedoreis heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. Thecopper(II) ions in the chalcopyrite arereducedtocopper(I) sulfide (which isreducedfurther tocopper metalin the final stage).

There are two categories ofcopper ore;sulphide orewhich isprocessedto enrich it before smelting, and oxideorethat is subjected to acid treatment. The majorproducersofcopper oreare Chile, USA and Australia, the vast majority of theorecoming from open pit mining.

The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams.

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.

Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised.

Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high

The next step inprocessingis called beneficiation. This is the first step in concentrating thecopperinto a more useable form. 5. Smelting and Extraction. The next step in theprocessflow is smelting for sulfideoreconcentrate and solvent extraction for oxideoreleach solution.Copperfrom the smelter is melted and cast as anodes, the ...

Metals such as zinc, iron andcopperare present inoresas their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is ...

The method involves thereductionofcopper(II) ions leached fromcopper oreto zero valence using chlorine treated solution prepared from chicken droppings at a temperature range of 60–70 °C. Theoresamples were pulverized to 250 micro millimetres and leached with hydrochloric acid to obtain leachate containingcopperions.

The principaloreofcopperiscopperpyrite andcopperis extracted from thisore. The different steps in extraction ofcopperare: Crushing and Concentration: Theoreobtained from mines are broken down into small piece by jaw crusher and then pulverized. Theorebeing sulphideoreis concentrated by froth floatationprocess.

The earliest evidence ofcopper smeltingoccurs in Serbian artefacts dating from around 5000 BC.Coppercan be extracted from oxideoresusing electrolysis (electrowinning) for low gradeores, or by the carbonreductionmethod of smelting for higher gradeores. Theprocessof extractingcopperfrom higher grade sulfideoresinvolves:

Copper processing-Copper processing- Roasting, smelting, and converting: Once a concentrate has been produced containingcopperand 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 ...

The flowsheet in this study is designed to get the maximum recovery from a large tonnage of porphyrycopper ore. TheCopper ProcessFlowsheetCopper OreCrushing. The crushing section consists of three-stageore reductionwith either a grizzly or vibrating screen between each crushing stage.

Extractingcopperfrom otherores.Coppercan be extracted from non-sulphideoresby a differentprocessinvolving three separate stages: Reaction of theore(over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilutecopper(II) sulphate solution.
