Indonesian Cobalt Production Capacity Set to Double by 2027

Indonesian Cobalt

Indonesian cobalt production capacity will more than double to 114,000 tonnes by 2027 from 55,000 tonnes in 2024, according to National Economic Council member Septian Hario Seto. The expansion comes from Indonesia's high-pressure acid leach (HPAL) operations, which process nickel laterite ores to extract both nickel and cobalt. However, Indonesian cobalt production capacity growth will likely plateau after 2027 due to rising project costs and slower-than-expected nickel consumption growth.

HPAL Operations Drive Cobalt Output Growth Despite Rising Costs

Indonesia's cobalt capacity expansion relies heavily on HPAL technology, which extracts cobalt as a byproduct of nickel processing operations. China Nonferrous Metals Industry Association's Xu Aidong confirmed that capacity increases will probably stabilize given mounting economic pressures. Meanwhile, rising sulfur prices used in hydrometallurgical production lines are increasing HPAL project costs significantly.

Mixed hydroxide precipitate (MHP) production maintains 30-40% profit margins even with nickel prices around $15,000 per tonne, partly due to cobalt content value. Indonesia exported nearly 1.56 million tonnes of MHP last year, with cobalt exports reaching approximately 44,350 tonnes. Therefore, Indonesian cobalt production remains economically viable despite commodity price volatility.

DRC Export Ban Creates Market Uncertainty and Technology Shifts

The Democratic Republic of Congo's cobalt export ban threatens to drive prices higher while potentially reducing long-term cobalt demand through technology adaptation. Seto warned that sustained export restrictions could backfire by accelerating battery chemistry changes to reduce cobalt content. As a result, the industry witnessed massive adoption of nickel-cobalt-manganese (NCM) 811 technology during 2017-2018 price spikes.

Indonesia processes MHP directly into precursors without crystallizing nickel sulfate first, streamlining production efficiency and reducing costs. The country views cobalt as inseparable from nickel production rather than an independent mineral resource. However, Indonesia recognizes its responsibility as a major producer to ensure reliable global supply chains.

Seto emphasized that Indonesia's position on nickel mirrors the DRC's influence on cobalt markets, requiring careful market management. Major producers must balance supply control with market reliability to avoid being perceived as unreliable suppliers. Consequently, both countries face pressure to maintain sufficient global supply while maximizing domestic value addition.

The Metalnomist Commentary

Indonesia's strategic approach to cobalt as a nickel byproduct positions the country advantageously in global battery supply chains while the DRC's export restrictions create market uncertainty. The doubling of Indonesian cobalt production capacity by 2027 could provide crucial supply diversification for battery manufacturers seeking alternatives to DRC sources, though technology shifts toward lower-cobalt chemistries may limit long-term demand growth.
