Sep 16, 1986· A process for refining brass and cuprous chloride includes contacting solid cuprous chloride with molten brass scrap which converts the zinc in the brass scrap to a zinc chloride fume and which reduces the copper values in the cuprous chloride to molten elemental copper.
Refining effects were estimated by comparing the effectiveness of micro structure changes with property changes of copper and its selected alloys from the group of tin bronzes. Keywords: copper alloys, tin bronzes, refining processes, structures and properties of alloys.
In refining copper, an aqueous solution of copper(II) sulphate is electrolyzed, using impure copper as the anode and pure copper as the cathode. At the anode, metal impurities higher than copper in the electrochemical series such as zinc, iron and lead are oxidized first, then copper loses its electrons to form copper(II) ions.
Copper sulfate is the basic salt in the electrolytic refining of copper, and it also finds wide use in the preparation of pigments. Carbonates Basic copper carbonates are formed when an alkaline carbonate is added to the solution of a copper salt.
