refining of blister copper

Copper processing - Roasting, smelting, and converting

The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels. This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining.

Copper Mining and Extraction Sulfide Ores

The blister copper produced by this process is 99% pure copper. The name ‘blister’ copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining. The anode casting turntable moves slowly round.

Fire refining of blister copper then removes most of the oxygen and other impurities, leaving a product at least 99.5 percent pure, which is cast into anodes. Metal extracting and . In copper production, this process produces blister copper, usually about 98% copper. Anode production/fire refining.

blister-copper - definition - English

Blister copper is processed in an anode refining furnace to remove most of the dissolved oxygen and sulphur. Converting produces blister copper named for the blisters of air/oxygen trapped in the molten material. Approximately 4 unit weights of concentrate are

Copper mining. Electrolysis

The blister copper is already virtually pure (in excess of 99% copper). But for today's market, this is not really pure enough! It is purified further using electrolysis. This is known as electrolytic refining. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus (see page 4). The

Gaseous Refining of Anode Copper | Request PDF

The refining of blister copper prior to casting into anodes consists of oxidizing the copper melt to remove sulfur and then reducing its oxygen content.

Copper Electrolysis Refining Plant, Purification of Copper by

Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. Copper Electrolysis Refining is a way of obtaining new, pure copper from old pipes, wires, circuits, and so on.

Continuous electrolytic refining process of cathode copper with

2019/5/1 · The blister copper is refined in the anode furnace to obtain an anode copper (copper content is from 99.2% to 99.5%). The anode copper is electrolytically refined in an electrolytic bath to obtain the cathode copper (copper content is above 99.9%) ( Iikhchi et al., 2007 ).

Copper Production Processes :: Total Materia Article

Blister copper is further refined as either fire-refined copper or anode copper (99.5% pure copper), which is used in subsequent electrolytic refining. In fire-refining, molten blister copper is placed in a fire-refining furnace, a flux may be added and air is blown through the molten mixture to remove residual sulfur.
