Review of copper pyrometallurgical practice: today and tomorrow
Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.
12.3 Primary Copper Smelting
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Then the cathode copper, which is as much as 99.99 percent pure, is extracted and recast. The blast furnace and converter may be omitted from the process if average copper content of the scrap being used is greater than about 90 percent. The process used by one U.S. facility involves the use of a patented top-blown rotary

Copper Refining: From Ore to Market
Mined rock typically contains less than 1 percent copper. That means to become a market-ready copper product, it must undergo a variety of physical and chemical processing steps.
Copper Processing | Equipment, Process Flow, Cases
Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
The Extraction of Copper
Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below). The anodes for this process were traditionally lead-based alloys, but newer methods use titanium or stainless steel. The cathode is either a strip of very pure copper which the new copper plates on to, or …

The Processing of Copper Ore Beneficiation
The copper ore beneficiation plant uses three processes: crushing, grinding and beneficiation. It's just that the selection of individual copper ore processing equipment and beneficiation technology will be slightly different. Among them, in the crushing process, the use of three-stage closed-circuit crushing can well complete the work of ore ...
Copper Mining and Processing: Everything you Need to Know
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
Copper Beneficiation Process – JXSC Mineral
1. Copper Flotation. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.
From Ore to Finished Product
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.

Copper Processing | Multotec
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
How is Copper Ore Processed
The pulp is fed into the second cell of each bank and a sulphide rougher concentrate is produced from cells, 2, 3 and 4 and returned to the first cell for cleaning. This cleaned sulphide copper concentrate is pumped by 3″ x 3″ DRL Pumps to the main sulphide cleaner concentrate pump box and thence to thickeners.
