1. Introduction. Aluminum is a critical material for the energy transition. It is the second mostproduced metal by mass after iron and demand for it has been growing globally at an average rate of % over the past decade [1].Aluminum's abundance makes it available with a benignly rising cost to output cumulative supply curve which can accommodate continuing rise in demand [2].

Aluminum occurs in nature in the form of chemically very stable compounds, in particular oxides. The raw material for aluminum production, alumina (Al 2 O 3), is refined from bauxite, which is an ore mined from strip production process also requires carbon anode production, electrolysis, casting, and secondary metal treatment.

The explanation: Diamond is harder than glass. When used as blast abrasives, harder materials are generally more "aggressive" than softer materials. Harder media like aluminum oxide, garnet and magnesium oxide are quite aggressive blast media. Softer media like baking soda and corn cob are gentler and nondamaging. 2.
