Global caustic soda market to reach 95.7 million tons by 2033, driven by steady demand across key industries at a CAGR of 1.41%. NEW YORK, NY, UNITED STATES, June 25, 2025 /EINPresswire.com/ -- ...

Activated alumina market to hit $1.60B by 2030, driven by water treatment, gas drying, and catalyst use across key industrial sectors.

Results from this work indicate that high-grade bauxite is present with available alumina – the portion of Ai2O3 that can be extracted under Bayer process conditions – exceeding 34.5% and ...

Results from this study confirm the presence of high-grade bauxite, with available alumina (extractable under Bayer process conditions) exceeding 34.5% and reactive silica measuring 3.14%.

Alumina refining relies on a process known as the Bayer circuit, or Bayer Process, which requires heat in the form of steam to extract and refine alumina from bauxite.

But some 98% of the supply chain is dominated by China, where gallium is extracted as a by-product of the Bayer Process in alumina refining, as well as from zinc processing. That status as a ...

Turning bauxite into alumina is a relatively simple process, called the Bayer Process, invented in 1887 by Carl Josef Bayer, and is still the method used today: Bauxite is crushed, then dissolved in ...

The bauxite is then refined through the Bayer process, where it is converted into aluminum oxide, or alumina. This refined alumina is the starting point for the next crucial step: electrolysis.

The Bayer process, invented by Austrian chemist Karl Josef Bayer in 1888, is widely used to refine bauxite into smelting-grade alumina, or aluminium oxide – the precursor to aluminium.
