An associated process is biooxidation. This is the oxidation of sulfide minerals associated with but not necessarily part of the mineral of interest to be extracted. Bioleaching is used today in commercial operations to process ores of copper, nickel, cobalt, zinc and uranium, whereas, biooxidation is used in gold processing and coal desulfurization.

Copper cathode is a pure form of copper metal that is produced through the electrolytic refining process. This process involves passing an electric current through a solution containing copper ions, which causes the pure copper to plate out onto the cathode. The resulting cathodes are used to produce various copper products such as wire rods, foil, …
The production of copper is just as diverse as its uses, with mines scattered all over the globe and several industry magnates accounting for production.
It is an important trace element for most organisms in all kingdoms. In humans, copper plays a role as a cofactor for numerous enzymes, such as Cu/Zn-superoxide dismutase, cytochrome c oxidase, tyrosinase, ceruloplasmin, and other proteins, crucial for respiration, iron transport and metabolism, cell growth, and hemostasis [ 1, 2 ].
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.
The production of refined copper from sulfide concentrates occurs through a multiple step process (see Fig. 1 ), which typically includes smelting, converting, fire refining and electrorefining ( Schlesinger et al., 2011 ).
Explore the essentials of copper production with our comprehensive guide on what is copper cathode and its significance in various industries.
For some of these elements, copper mining complements the production infrastructure of the by-product (e.g. gold, silver, lead, zinc or molybdenum). Other minor metals have limited or no own production infrastructure (e.g. selenium or tellurium).
The present work provides a review of the copper production from sulfide minerals focused on the concentration data of the main stages of the process (shown in Figure 1) and the recent advances in the development of technologies for copper mining.
A step by step hydrometallurgical process for the production of copper cathode was developed after a two-step precipitation from leaching solution of copper oxidized ore, followed by copper concentrate leaching and electrowinning.
In this process copper concentrate is fed into the smelter with oxygen-enriched air. The fine concentrate reacts or 'flashes' instantaneously as the sulfur fraction of the copper sulfides is burnt and becomes sulfur dioxide gas.
The Mined copper ore is initially crushed, milled and concentrated by ore beneficiation process into a fine, gray powder called copper concentrate. If the nature of ore is sulphide, froth floatation process is adopted to do the beneficiation wherein the 1 % copper containing ore is converted to more than 25 % copper containing concentrate.
However, the journey from raw copper ore to refined copper metal involves a series of intricate processes, necessitating specialized equipment and efficient processing lines.
With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content.
Today, a continuous casting and rolling process produces virtually all copper rod. Benefits of continuous casting include less microsegregation of impurities, reduction of copper oxide particles on the surface, fewer steel inclusions resulting from contact with mill rolls, almost total elimination of welds, and lower overall processing costs.

Copper oxide ores undergo a three-step process to achieved high levels of concentration. First, in a process called heap leaching, sulfuric acid is used to separate copper from the ore. Next, the solvent extraction stage moves the copper from the leach to a solvent, removing impurities.

Copper production from recycled end-of-use objects is about 15% of copper-from-ore copper production. Electrochemical processing is always used in producing high-purity copper: electrorefining in the case of pyrometallurgical extraction and electrowinning in the case of hydrometallurgical extraction.
Comparing copper production of six other metals, as highlighted by Benjamin S., in (2019) [2], it becomes evident that copper's environmental impacts per kg of production are higher.
