Bauxite Downstream Processing: Key to Breaking Free from Middle-Income Trap

Jakarta — NEXT Indonesia Center contends that downstream processing of bauxite into alumina and aluminium can increase added value by dozens of times over and represents the key for Indonesia to escape the middle-income country trap.

“Downstream processing is a tangible solution for Indonesia to strengthen our national industrial structure and end the habit of selling raw bauxite,” said Christiantoko, Executive Director of NEXT Indonesia Center, in a statement issued in Jakarta on Monday.

He explained that Indonesia possesses bauxite reserves of approximately 2.9 billion tonnes, yet has historically sold the majority in raw form.

According to NEXT Indonesia Center’s analysis, international bauxite prices in 2024 stood at around 59 US dollars per tonne. If bauxite is processed into alumina, its value can reach 478 US dollars per tonne—approximately 8.1 times higher.

“If processed into aluminium, based on the average price over the past 20 years, the added value could surge to 59 times higher,” he stated.

Christiantoko noted that the substantial price differential between raw material and derivative products demonstrates significant economic potential yet to be optimised domestically.

He cited the bauxite-aluminium downstream processing project in Mempawah, West Kalimantan, operated by PT Borneo Alumina Indonesia—a collaborative entity between PT Aneka Tambang Tbk and PT Indonesia Asahan Aluminium under MIND ID—with an investment value of approximately 6.32 billion US dollars.

He said the project symbolises the transformation from raw material exporter to producer of high-value-added aluminium, with full operational capacity targeted for 2028–2029.

NEXT Indonesia Center also noted that during 2020–2024, China earned 175.6 billion US dollars from aluminium exports, whilst Indonesia obtained approximately 1.9 billion US dollars from bauxite exports during the same period.

“This fact demonstrates that command of smelter technology determines global economic position far more than mere mine ownership,” he stated.

Christiantoko added that domestic aluminium demand is estimated to rise from approximately 1,200 kilotonnes per annum in 2025 to 8,500 kilotonnes by 2055, making the strengthening of processing industry capacity increasingly urgent.
