Copper is a reddis brown element and it is a metal. Its atomic number is 29 and atomic mass number is 63.5. The important ore of Copper is Copper pyrite, CuFeS 2. Introduction to extraction of copper from its ore
Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydrometallurgical process.
Tailings produced from the milling of sulfide ores primarily copper, lead, and zinc ores may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or 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.
Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at Timmins, Ontario , to irregular veins and disseminations associated with granitic to dioritic intrusives as in the porphyry copper deposits of Broken Hill ,
Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
steps of extraction of copper from chalcopyrite; Copper Mining amp; Extraction Process Flow Chart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process.
Copper occurs both in native state as well as in combined state. The chief ore of copper are Copper Pyrite (CuFeS2) Cuprite (Cu2O) Cupper Glance (Cu2S) Malachite [CuCO3.Cu(OH) 2] Extraction of copper Copper is extracted from is chief ore, copper pyrite.
The chief ore of copper are Copper Pyrite (CuFeS 2) Cuprite (Cu 2 O) Cupper Glance (Cu 2 S) Malachite [CuCO 3.Cu(OH) 2] Extraction of copper Copper is extracted from is chief ore, copper pyrite. The various steps involved in the extractions are a. Crushing and concentration The ore is crushed in jaw crusher and powdered in ball mills. It is concentrated by froth floatation process.
The Problem with copperpyrite ores. This flowsheet, is designed for the treatment of a copperiron sulfide ore containing appreciable values in gold.The major portion of the gold is associated with the copper but the pyrite contains appreciable gold values also.
Copper is extracted from its principal ore copper pyrites (CuFeS 2).The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur.
Copper is much rarer, but fortunately can be found in highgrade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from lowgrade ores as well.
EXTRACTION OF COPPER. On industrial scale copper is extracted from its sulphide ore known as copper pyrite (CuFeS 2) by smelting method. STEPS OF EXTRACTION. For Crushed ore is suspended in water containing pine oil. A blast of air is passed through the suspension. The particles of ore get wetted by oil and floats as a froth
Copper is a reddis brown element and it is a metal. Its atomic number is 29 and atomic mass number is 63.5. The important ore of Copper is Copper pyrite, CuFeS 2. Introduction to extraction of copper from its ore. Extraction of copper from copper pyrites involves the following steps.
The finely crushed ore is concentrated by Froth EXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite (CuFeS 2). Chalocite (Cu
Extraction, purification and uses of aluminium This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses.
The SX/EW process has provided the copper industry with a tool that makes the extraction of copper from its ores significantly more environmentally friendly than by
Web search hints Porphyry copper Nazca subduction Global volcanism smithsonian. Copper can be extracted from its ore by Underground sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit 90% of ore is mined by this method.
Smelting in extraction of copper The roasted ore mixed with silica as flux is heated in a blast furnace by a blast of hot air. Most of the FeO is removed as a slag and a molten mixture of Cu 2 S and FeS called matte, get collected in the hearth of the furnace.
Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction

Extractive Metallurgy of Copper details the process of extracting copper from its ore. The book also discusses the significance of each process, along with the concerns in each process, such as pollution, energy demand, and cost.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Twostage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3.
The principle ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are Crushing and Concentration The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized.
