Alumina Solution

Alumina Solution is a fluid solution of Bauxite and Water. It is only used to produce Aluminum Scrap for further processing.

Tips

 * The Silica produced as a byproduct does not suffice for Aluminum Ingot production (using the standard recipe), more of it has to be produced from Raw Quartz. It can be omitted with the Pure Aluminum Ingot alternate recipe, which however reduces ingot yield by 25%.
 * Routing 1/3 of the Scrap into Aluminum Ingot Foundries and the rest into Pure Aluminum Ingot Smelters consumes exactly all of the Silica byproduct, and reduces ingot yield by 12.5%.
 * Using the Sloppy Alumina alternate recipe produces no byproduct Silica. This plus Pure Aluminum Ingot reduces ingot yield by 10%, but greatly increases energy efficiency.

Trivia

 * The in-game refinement process resembles the real-life refining process called Bayer process.
 * Alumina is another name for aluminum oxide, Al2O3.
 * In real life, Alumina Solution is used both as a refining intermediate and as a polishing abrasive.
 * Alumina Solution is technically a suspension or slurry rather than a true solution, as aluminum oxide is insoluble in water.
