HPA is traditionally derived from aluminum via bauxite, producing an end product of variable end product quality and high levels of impurities. It is a carbon intensive that has seen little evolution since the 1880s. FYI intends to use kaolin clay as a feedstock for its HPA production, which will have a much lower environmental impact.

Aluminum Manufacturing - IFC

The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (usually of the surface type), bauxite ore is re-moved to a crusher. The crushed ore is then screened and stockpiled, ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing, size classification, and

It strips oxygen from the ore to make pure iron, known as pig iron, which is turned into steel in an electric arc furnace. But the waste product — from combining carbon in the coal with the oxygen in the ore — is large quantities of carbon dioxide. The entire process emits an average 2.2 tons of CO2 for every ton of steel.

The World's Leading Bauxite Producing Countries - WorldAtlas

Bauxite is a soft limonite iron ore rock with portions of its iron composition replaced by aluminum. Bauxite forms when silica leaches out from laterite soil. Bauxite does not exhibit any particular composition instead it is just an assortment of clay minerals, aluminum hydroxides, and hydrous aluminum oxides.

9 Ore Deposits and Economic Minerals – Mineralogy

If aluminum-rich laterite lithifies to become rock, we term it bauxite. We mine laterites and bauxites from open pits to produce nickel and aluminum and, sometimes as a secondary commodity, iron. Chapter 7 discussed the formation of laterites and bauxites. See especially Box 7.1. 9.3.3.5 Phosphorites 9.97 Cormorants on a guano island
