From Ore to Finished Product
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Our process | Umicore Precious Metals Refining
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.
Cobalt processing | Uses, Supply, & Facts | Britannica
For copper-cobalt ores, a sulfide concentrate is roasted under controlled conditions to transform most of the cobalt sulfide to a soluble sulfate while minimizing the change of copper and iron to their water-soluble states. The product is leached, the resulting solution is treated to remove copper and iron, and the cobalt is finally recovered by electrolysis.

Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it …

Copper Refining
In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

Copper Mining and Processing: Processing Copper Ores
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …

Electrolysis of the new solution. 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 …
How a copper smelter works
the purity level to 98-99 per cent and the copper is then cast to form anodes. The anodes are placed in tanks with steel cathode plates. In the subsequent electrolytic refining process, copper migrates from anodes to cathodes, which ultimately have a copper content of 99.99 per cent or higher.
Review of copper pyrometallurgical practice: today and tomorrow
Copper electrorefining and electrowinning facilities (e.g., China and Japan) favour the patented MIM stainless steel blank technology rather than using prepater sheets with the inherent mechanical handling problems (e.g., cross rods). The licensed ISA Process currently accounts for over 35% of global copper refining capacity.

Flowsheet Options For Processing Copper Gold & Gold …
The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations.
copper extraction and purification
Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper - hence "blister copper") and then cast into anodes for refining using electrolysis.

Copper processing
Copper processing - Ores, Refining, Smelting: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may …
