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 copper tin alloy about 3000 BC, was the first engineering material known to man

The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps High purity scrap copper is melted in a furnace and then reduced and cast into billets and ingots lower purity scrap is refined by electroplating in a bath of sulfuric acid Alloys

The ore is treated with dilute sulphuric acid This trickles slowly through the ore dissolving copper to form copper sulphate The copper is recovered by electrolytic refining Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off

Copper: smelting and classification The smelting of copper Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate Then, after being smelted, refined copper and copper products are yielded There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical

Processes: copper mining and production Copper is found in natural ore deposits around the world This page explains copper mining: the production route taken from ore containing rock to a final product that is the highest purity commercial metal in existence and used in a wide variety of applications essential to modern living

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and direct smelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger

For copper oxide ore, electrowinning is the final stage in the process of hydrometallurgy, in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte an electric current is applied through an inert anode, resulting in the plating of copper onto 99 9 pure copper cathodes

Jan 14, 2019 The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors Currently, about 80 percent of global copper production is extracted from sulfide sources

Secondary production Copper and alloys with a high copper content are recycled to obtain pure copper The metals are heated with oxygen enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed The Isasmelt process described above is often used for secondary copper production

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes, which will ultimately be made into products for everyday use The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0 5 by mass Ideally, the figure should be closer to 2 The worlds largest copper ore deposits are found in Chile on the west coast of South America This is due to the volcanic activity that is part of the process that created the Andes mountain chain

Pug mills are a key piece of equipment in the copper smelting process, serving to mix and condition several components copper concentrate, flux, reverts, matte recycle, and dust recycle, for reintroduction into the smelter Material Handling In addition to our pug mills and ore drums, FEECO can supply the necessary material handling equipment to transport copper around the processing facility

A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here Conventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refined

Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting Smelting these materials would require too much energy and very large furnace capacities The copper ore coming from the mine 0 5 1

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased

Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec ades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores With the exception of leaching solvent extrac

The major portion of the worlds production of copper is utilized by electrical industries most of the remainder is combined with other metals to form alloys In variety of uses, the alloys of copper surpass all other nonferrous alloys and comprise mixtures of copper with zinc, tin, nickel, aluminum, lead, manganese, and other elements

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0 5 by mass Ideally, the figure should be closer to 2 The worlds largest copper ore deposits are found in Chile on the west coast of South America This is due to the volcanic activity that is part of the process that created the Andes mountain chain

Nov 22, 2015 The smelting process of copper smelting furnace is beneficiation, its purpose is to concentrate all the gangue content in slag, and useful metal in blister The raw copper ore

Pug mills are a key piece of equipment in the copper smelting process, serving to mix and condition several components copper concentrate, flux, reverts, matte recycle, and dust recycle, for reintroduction into the smelter Material Handling In addition to our pug mills and ore drums, FEECO can supply the necessary material handling equipment to transport copper around the processing facility

It is not uncommon for copper mines to process additional metals at their facilities Many copper mines also produce gold, silver, and/or molybdenum, and less commonly, may also produce platinum group metals, nickel, zinc, and even uranium Conclusion Coppers unique combination of properties lend it to a diverse range of applications

Copper extraction refers to the methods used to obtain copper from its ores The 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
