 · The comparison is based on the processing of an equal amount of iron oxide in bauxite residue and iron ore. The results showed that almost twice as much energy is required for direct smelting of bauxite residue than for iron ore smelting (~ GJ). This is due to the large amount of slag generated, which needs to be processed. The energy required for the smelting of lowalumina bauxite .

FOCUS: Pricing bauxite and alumina | Metal

As the market matures in this way, price assessments can inevitably evolve to become indices, like those which have become the norm in alumina and iron ore. At last year's Metal Bulletin bauxite and alumina conference in Miami, Alcoa forecast an increase in demand for seaborne bauxite to 130 million tonnes by 2026, growing at an average rate of 8% per year, primarily driven by Chinese demand.

Bauxite | Geoscience Australia

Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al 2 O 3 .3H 2 O), boehmite (Al 2 O 3 .H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world's largest producer of ...

Extraction Process of Aluminium from Bauxite Ore

 · In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or "digested," at atmospheric pressure.
