High-purity copper that has undergone an electrolytic refining process is referred to as electrolytic copper cathode. One of the most common kinds of copper is utilised in manufacturing, electronics, and other sectors including construction and construction.
The following steps are involved in the manufacturing of electrolytic copper cathode:
Mining and Concentration: Copper ore is extracted from the soil and concentrated to yield the necessary copper minerals using techniques like flotation, grinding, and crushing.
The concentrated copper ore is burned in a furnace with a reducing agent to eliminate impurities and transform it into blister copper, which normally contains between 98 and 99% copper.
The blister copper is then put through an electrolysis process known as electrorefining. A high-purity copper sheet serves as the cathode in this procedure, with the blister copper acting as the anode. The cathode and anode are both submerged in an electrolyte solution that contains sulfuric acid and copper sulphate.
During electrolysis, copper ions from the blister copper anode disperse into the electrolyte and move in the direction of the cathode. The copper cathode’s size and purity steadily increase as pure copper is gradually put on it at the same time.
Harvesting and casting: The electrolytic copper cathode is taken from the cathode plate once the appropriate level of purity has been reached. The cathodes are then commonly cast into standard-size rectangular or cylindrical shapes after being cleaned and dried for ease of handling and transportation
High electrical conductivity, superior corrosion resistance, and consistent quality are all characteristics of electrolytic copper cathodes. They are extensively utilised in the creation of printed circuit boards (PCBs), transformers, electrical lines, cables, and other products that call for high-purity copper.
The Global Electrolyte Copper Cathode market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Construction of a facility has been done by Aurubis to extract copper and nickel from recyclable materials. The site’s capacity for hydrometallurgical recycling will improve thanks to the new Bleed treatment Olen Beerse (BOB) facility, which processes electrolytes, or “bleed,” more quickly in order to recover more precious metals.
High levels of acid, copper, and nickel may be present in the bleeding products of copper electrolysis or electrowinning procedures.
From the electrolyte stream produced in tank houses during metal production at Aurubis’ Beerse and Olen facilities, the new plant will recover metals including nickel and copper.
At the BOB, contaminants will be eliminated in four steps while metals will be recovered:
