Liulin Senze Coal & Aluminum, a Chinese company, will produce alumina using low-grade ore

The developer of the new technology said that in July, a Chinese company Liulin Senze Coal & Aluminum would begin producing alumina in its Shanxi factory from low-grade bauxite thanks to a technology developed in France.

China's bauxite reserves are large, but many of them are of poor quality. This makes the country dependent on imports of bauxite to meet the demand for alumina, a critical input for the production of aluminium. China is the largest producer of aluminum in the world.

Romain Girbal, CEO of IB2, said that the process developed by French green technology company IB2 allows low-grade bauxite to be converted into high-quality aluminum by neutralizing impurities like silica and sulfur.

He said that the plant in Shanxi is expected to produce 50,000 tons of bauxite a month by December, and IB2 plans to increase this to 3,000,000 tons per year over the next two-years.

He said that IB2 technology was being used in a 22-year contract signed with Liulin Senze Coal & Aluminum.

Liulin Senze Coal & Aluminum has not responded to any requests for comment.

Girbal stated that IB2 has advanced discussions about providing technology with five other Chinese manufacturers.

The technology may help China reduce its reliance on imported Bauxite to produce alumina, but the long-term production scale that can be achieved using this technology is still unknown.

The global bauxite supply is in doubt after Guinea's military-led government cancelled 129 mineral exploration licenses, including some relating to bauxite.

Customs data shows that Chinese bauxite exports increased 12.4% in 2024, from 158.77 to 158.77 millions tons.

According to the International Aluminium Institute, China produced 72 million tonnes of primary aluminum last year. Reporting from Ashitha Shivaprasad, Bengaluru. Editing by Pratima Deai and Susan Fenton.
