Alkali metals are very soft, shiny, highly reactive metals (because they want to lose an electron).
With more reactive metals, annealing can be done in a vacuum furnace.
Alkaline earth metals are soft, silvery, reactive metals (having two spare electrons they are looking to shift) – think of magnesium burning brightly in air.
Electrolyte selection is key for designing new processes for the electrochemical extraction of reactive metals, and the new work demonstrates that more electrolytes are available for extracting metals.
Provides a direct application of the fundamentals of thermodynamics and kinetics to the industrial production of metals from their ores, e.g., iron, aluminum, or reactive metals and silicon.

Other modifications allow application of the method to highly chemically reactive metals and decrease the sample preparation time.
Anodic oxidation of reactive metals such as Al and Ti produces oxide films with self-organized arrangements of nanoscale pores.
So we are basically now adding at least three or four candidate electrolytes that could be used for metal extraction, in particular for what we call reactive metals such as aluminum, niobium, titanium, or the rare earths," Allanore adds.
Examples include pure reactive metals, intermetallic, metal-metalloid composites, and thermites; the latter two types of materials include nano-composite and nanostructured compositions.
Particle reactive metals (e.g. Pb) displayed little enrichment, implying that they were retained up catchment, whereas more soluble metals (e.g., Cu and Zn) showed evidence of concentration.
