Refining of blister copper EPrints

The copper anodes from fire refining are placed in a tank filled with solution of copper sulphate to which is added some sulphuric acid as electrolyte. The cathodes are pure copper starting sheets suspended between the anodes. Anodes are connected to the positive and catho- des to negative terminals of the source of current.

Recycling of Copper

Secondary copper can be used for the manufacture of these materials, though still within stipulated quality limits for impurities. Where scrap copper is associated with other materials, for example after having been tinned or soldered, it will frequently be more economic to take advantage of such contamination than try to remove it by refining.

Your Process Challenge for Copper Heraeus

Blister copper is then casted into intermediary anodes which are further refined into copper cathodes (99.99% pure copper) through an electro-refining process. Cathodes are re-melted and processed into final end user products. Blister copper feed can be partially or fully replaced by secondary scrap to recycle end of life copper.

How copper is made material, used, processing, steps

Even though copper blister is 99% pure copper, it still contains high enough levels of sulfur, oxygen, and other impurities to hamper further refining. To remove or adjust the levels of these materials, the blister copper is first fire refined before it is sent to the final electrorefining process.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Secondary production. Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.

Antimony Recovery from End-of-Life Products and Industrial

Feb 08, 2016 Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and
