Amphirol is a screw-like vehile used to farm bauxite residue. As the amphirol travels, it compresses the residue and creates tracks. These furrows allow the water, which has been squeezed from the residue, to drain into the perimeter channel .





Copper Anodes are composed primarily of copper metal and copper oxides (> 80%) but can still containing other residual metals. Anodes are used as source of copper in the electroforming process. 





The Bayer Process, developed by Carl Josef Bayer, is a method for producing alumina from bauxite ore.



Concrete, when made from geopolymer binder instead of Portland Cement, produces up to 77% less CO2 emissions.



Electroforming, in both hydro- and pyrometallurgy, is the last step in the process of refining copper. In electrowinning as in electrolysis, CU2+ ions in a dissolved copper sulfate solution are attracted to the negative charge at the cathode, and form directly to the surface with up to 99.99% purity.





Gardanne, a town in the Provence region of France, is the site of the first factory to ever produce red mud. The factory opened in 1894, five years after the patent for red mud was filed.



Geopolymer is an alternative cementitious material synthesized by combining source materials that are rich in silica and alumina such as fly ash (FA), ground granulated blast furnace slags (GGBFS) with strong alkali solutions.


 
A cathode – a 50 to 80 kg copper square – is produced when pure copper separates from unwrought copper in an electrolytic refining process. The resulting cathode has a purity greater than 99.95%. 





A Mill breaks material into smaller parts. In processing copper slag two types of mill are most common: the SAG mill, and the ball mill.






Overburden refers to the material between the ground surface and the material to be mined. It is different from tailings (see tailings), in that is has not been processed, and is therefore not contaminated with toxic elements. Overburden is used as a construction aggregate for buildings and roads, as well as for contouring land or in place of soil.



Recycling
Each recycling facility usually specializes in a specified form of copper recycling, be it the coils from refrigerators, car radiators, e-waste, etc. Due to the particularized method of mechanically “mining” this urban copper ore stream. This “Secondary copper concentrate” is then returned back into the production cycle at pyrometallurgy and continues in much a similar way than the raw mined ore. In this secondary cycle, slag is also produced, up to 3X per unit copper produced.



Slag is a by-product obtained during the separation of a given metal from its raw ore source. Slag from copper is particularly interesting given it’s wide array of possible uses: the material can be used as an abrasive material, in road construction, and as ballast. Despite the increasing rate of copper slag reuse, a huge amount of  annual copper slag production is disposed in dumps or stockpiles to date. One of the greatest potential applications for reusing copper slag is in cement and concrete production.





Tailings are the materials left behind after the chemical and mechanical refining of raw ore. Through this process the valuable material (concentrate) is separated from the non-valuable material, or tailings. This left-over matter has been contaminated with various acids and leachates. 

Bauxite tailings, more commonly referred to as red mud, is the waste substance which is created during the production of aluminum oxide. Industry experts believe that more than 150 billion tons of the substance is produced each year. Management of this huge amount of waste is one of the biggest challenges facing the aluminum industry.
