Copper Smelting — An Overview

Q·S Oxygen Process The QS process is described in a paper presented in 4 As a coppersmelting process, there has been no further development over the past five years; however, a semicommercial plant to treat lead concentrates started up in March 1981 at Berzelius in Germany.

The smelter separates precious metals in a copper bullion, from mostly all other metals, concentrated in a lead slag, further treated at the Base Metals Operations. After leaching out the copper in the leaching and electrowinning plant, the precious metals are collected in a residue that is further refined at the precious metals refinery.

Copper production environmental impact

The resulting copperbearing solution is collected and pumped to a solvent extraction plant. Smelting and Extraction. Sulfide Ore. The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this smelting process the copper .

Copper Purifiion Process

Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper hodes during electrolysis. In electrolysis, it is the positive terminal. Oxidation occurs at the anode. The anode is replaced when it's been eroded too far and risk falling apart.

COCOP: Copper smelter optimization | SPIRE

Summary: Plantwide optimization tool for copper smelter operating flash smelting furnace, PeirceSmith converters and anode and slag cleaning furnaces. The main goals are to maximize feed rate (increasing production rate), save resources and reduce emissions per ton produced copper. Challenges: Interrelated Batch and continuous process included.

The Mitsubishi Process, History

New Mitsubishi Process plant was established, with a design capacity of 204,000 mtpy copper. This new Mitsubishi Process plant has, as planned, successfully rationalized Naoshima's copper operations by completely replacing the older conventional (Reverb/PS) smelter, the original Mitsubishi Process plant, and their respective anode casting plants.

Copper Mining Extraction Process Flow Chart

Aug 26, 2015 · Copper Mining 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. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).

Hydrometallurgical smelter dust treatment

Dec 11, 2019 · Process description. The hydrometallurgical smelter dust treatment process normally requires leaching, arsenic precipitation, and copper recovery. Valuable metals recovery takes place using mechanisms such as precipitation, electrowinning, or crystallizing, with impurity metals precipitated and directed to the tailings pond or waste area.

Primary Copper Smelter and Refinery as a Recycling Plant—A ...

The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and firerefining can use a limited amount of secondary materials. Molten copper can effectively dissolve many metals, from valuable noble metals to harmful impurities such as bismuth.

Copper Smelting

Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several PierceSmith converters operated in batches. Automating scheduling provides advisory information to operators.

A Look at the Largest Copper Smelters

Nov 20, 2019 · Chuquicamata (Codelco)— mta. Codelco's Chuquicamata smelter is fed by the Chuquicamata (or Chuqui) copper mine, one of the world's largest openpit copper mines in the world. Loed in northern Chile, Chuqui's smelting facilities were initially installed in the early 1950s. 02. of 11.

Copper Smelter

Copper Smelting Process: Historically, the most abundant copper bearing ore was called chalcopyrite, CuFeS 2. This ore is first enriched by a process called flotation. Powdered ore is mixed water as a slurry and then further mixed with oil and a chemical called amyl xanthate.

DAYE copper smelter

Jun 30, 2021 · Commissioning of the equipment upgrades and improved copper smelting process began in March 2019, with James Coveney Senior Process Engineer Ross Andrews Process Design Manager, traveling to China to visit the site. "The aim of this project was to upgrade the lance so the process could operate with a higher oxygen enrichment," says James.

The Mitsubishi Process, Advantages

Low atmospheric emissions, particularly sulphur dioxide bearing, than any other copper smelting and converting process. Allowance for compact and standard design of acid plant. This contrasts sharply with other processes, where enormous variations in gas flowrate and strength mandate the use of larger and less efficient customdesigned acid plants.

Copper Smelting Technology Trends

Aug 23, 2017 · Copper Loss in Slag: The slag from the smelting process is cooled, crushed and ground before flotation to recover copper sulphides and copper metal. Typically, slags may contain 3% copper .

Bernard Schilberg of PMR shares details on new copper ...

Jun 18, 2020 · This will be the Cadillac among the copper smelting facilities in the world." He expects the plant to be operational in the fourth quarter of 2022. Ames Copper Group will create 46 jobs in Cleveland County, North Carolina, including casting workers, maintenance .

Copper Mining and Processing: Processing Copper Ores ...

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

Copper Smelting Process

Apr 09, 2010 · Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a byproduct. 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.

Copper Smelting Market

Based on process, the copper smelting market can be divided into reverberatory smelting, oxygen flash smelting, acid plant, tappingtheflash furnace, converter furnace, and others. Reverberatory smelting and oxygen flash smelting are methods that require the resultant molten copper to be further processed to attain % pure copper.


The smelting process breaks the elements apart and the sulfur is driven off as sulfur dioxide gas. Kennecott's smelter is one of the most modern and cleanest in the world. It captures percent of the sulfur dioxide emissions produced. We clean the sulfur dioxide gas and pipe it to a doublecontact acid plant.
