Smelting is the process of applying heat to ore in order to extract a base metal. Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. Most copper ores are sulphur-based and smelting releases sulphur dioxide, an air pollutant known to have many harmful effects.
Electrode consumption was 4 kilograms per metric ton of material smelted. The Westly furnace, used 3-Phase, 50-cycle alternating current at 112 to 230 volts. The several sizes were of 200- to 900 kw. capacity, and the power consumed in the large furnace was less than 700 kw.-hr. per metric ton of ore smelted.
Copper smelting is the process through which the copper ore is purified through intense heating and melting to derive high quality copper or copper products. As most copper ores are sulphur-based, the smelting process releases sulphur dioxide, an air pollutant which has many harmful effects. When the concentration of sulphur dioxide is …
In the 70 year history of the Flash Smelting process for sulphide concentrates [2], significant equipment development was needed in the completely new smelting concept, and specifically the novel smelting furnace (FSF) and its key equipment. Already from beginning, the very low use of external fuel and a superb sulphur fixation were evident.
The copper smelting market can be segmented based on process, end-user, and region. Based on process, the copper smelting market can be divided into reverberatory …
A secondary copper smelter is defined as any plant or factory in which copper-bearing scrap or copper-bearing materials, other than copper-bearing concentrates (ores) derived from a mining operation, is processed by metallurgical or chemical process into refined copper and copper powder (a premium product).

In the present paper, recovery of valuable metals from copper smelter slag of Balkhash copper plant (Kazakhstan) was investigated. To recover Fe, Zn and Cu to water-soluble form, the mixture of 150 g of copper slag and 60 g of 85% sulfuric acid was granulated and then roasted in the temperature range of 473–643 K (200–370 °C) …
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical …

This model defines the relationship between copper ore grade and energy inputs for mining and beneficiation processes for different type of copper extraction sites as follows: (2) E = α × G − β where G represents the ore grade, E is the energy use for obtaining copper concentrate in MJ per kg and the parameters α and β are regression ...
For example, in the Kamoa mine in the DRC nearly 70% of mineralogy consist of the high copper content bornite, covellite and chalcocite. The above-mentioned mineralogy results in concentrate quality at above ~60% copper content. Finally, the copper rich minerals include significantly less iron, which drives a quality challenge at …
