and refining of copper

Slags, Copper Refining

Slag, copper refining is defined as : Substance produced at high temperature in a liquid state, by melting mixtures of metal oxides and non-ferrous metals (from primary sources such as copper ores, matte, or anodes) or by oxidizing metals (from copper rich materials such as metals, alloys or metal oxides).

Electrorefining Copper

 · In the second phase, a single-channel refining cell was built and tested. The effects of flow rate, current density, and grain refining additives on copper refining in this cell were determined. In the final phase, a larger channel cell with multiple electrodes (four anodes and three cathodes) was designed and operated.

Liberating Copper and Nickel: A True Story

The copper matte is mixed with reagents in a converter to rid of the remaining sulfides and oxides to produce blister copper containing 97-98% copper. The blister copper is casted into anodes for electrolytic refining where the impure copper is electroplated into pure copper cathode.

12.3 Primary Copper Smelting

Fire refining and electrolytic refining are used to purify blister copper even further. In fire refining, blister copper is usually mixed with flux and charged into the furnace, which is maintained at 1100°C (2010°F). Air is blown through the molten mixture to oxidize the copper and any remaining impurities. The impurities are removed as slag.

The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.

Copper Environmental Profile

Copper has six major life cycle phases: mining, smelting and refining, semi-fabrication, product manufacture, use phase and recycling. Recycling takes place both at smelters for copper production and at fabricators for production of semi-finished products. The International Copper Association''s Copper Cathode Life Cycle

The electrolytic copper production is processed in the huge copper electrolytic tank fulfilled with copper electrolytic solution. Even the best chemical method cannot remove all the impurities from the copper but with electrolytic refining it is possible to produce 99.99 pure copper whatever method is used to manufacture copper from its ore .

60 Centuries of Copper: Smelting, Refining and their Products

The final products of smelting and electrolytic refining are cathodes, cast often in the form of copper wirebars and cakes.* The casting are subsequently worked in various ways into wrought forms. Re-melted cathodes may also be cast into ingot bars suitable for the preparation of alloys.

17.5: Refining of Copper

 · 1. Figure 17.5. 1: The electrolytic purification of copper. In such a cell a thin sheet of high-purity Cu serves as the cathode, and the anode is the impure Cu which is to be refined. The electrolyte is a solution of copper (II) sulfate. Some of the impurities are metals such as Fe and Zn which are more easily oxidized than Cu.

Copper Refining: Explained Step-by-Step

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.

Refining (metallurgy)

Electrolytic refining. The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper sulphate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode.

The fluid flow in a copper refining cell is calculated three dimensionally, using the CFD-software package FIRE. The simulation is based on density variations in the boundary layer at the electrode surface. Calculations and LDA-measurements are in good correspondence. The actual glue concentration in the cell is calculated, too.

In Electrolytic refining, the impure metal is made to act as an anode. A strip of the same metal in pure form is used as the cathode. They are put in a suitable electrolytic bath containing a soluble salt of the same metal. The more basic metal remains in the solution and the less basic ones go to the anode mud. Copper is refined using an electrolytic method.
