15/3/2018· Article presents an overview of the processes and standards of aluminum additive manufacturing (or 3D printing), as well as examining the viability of the process for large scale production. By Joseph C. Benedyk, Editor. Introduction For decades, additive
The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.
Calcined petroleum coke is the major raw material required for the production of carbon anodes used in the aluminium smelting process. Green coke (raw coke) is the product of the coker unit in a crude oil refinery and must possess sufficiently low metal content in order to be used as anode material.

There is disclosed a continuous process for the manufacture of aluminum sulfate by the reaction of sulfuric acid with an alumina-containing solid in an aqueous suspension. The reaction stream is passed into a continuous flow reaction zone that is maintained at a temperature controlled from 225° to 260° F. and under superatmospheric pressure, preferably, autogenic pressure.

Production costs for smelters are highly dependent on the global economic environment, which affects oil prices, and the prices of other commodities, including those that create smelters’ input costs. For instance, during the global economic crisis in 2009, production costs for aluminium smelters decreased between 30 and 40% compared to the record high costs in […]
