Indonesia’s Morowali Nickel Hub Confronts Production Disruption and Intensified HPAL Method Scrutiny
Indonesia’s Morowali Industrial Park, a pivotal center for nickel production on Sulawesi Island, is currently facing a suspension in operations and heightened examination of nickel extraction techniques in the wake of a landslide last month. This incident has amplified concerns regarding the safety of high-pressure acid leaching (HPAL) methods employed in nickel extraction and the long-term reliability of a vital supply source for the burgeoning battery industry. The Morowali Industrial Park is a key region for global nickel supply chains, and any disruptions have significant implications for battery manufacturers and the electric vehicle market.
HPAL Method Safety Under Examination
While the HPAL method is recognized for its cost-effectiveness and reduced carbon footprint compared to other extraction processes, it generates approximately double the volume of tailings. This substantial waste byproduct necessitates meticulous waste management strategies to avert operational interruptions and potential environmental hazards.
Landslide at Tailings Site Prompts Investigations
The recent landslide occurred within a tailings storage area associated with PT QMB New Energy Materials, according to sources close to the matter. This incident tragically resulted in two fatalities and one worker remains missing, prompting serious safety investigations and raising questions about tailings management practices at the industrial park.
Reduced Output Reported by Nearby Producers
Nickel producers operating in proximity to the affected area have also reportedly scaled back their output. These producers, preferring anonymity due to the sensitivity of the situation, have indicated concerns about broader safety protocols within the industrial park.
Global Supply Concerns Rise Amidst Indonesian Outages
Indonesia, which accounts for over half of the world’s total nickel output, faces the prospect of contributing to global supply vulnerabilities should these production interruptions persist. Battery manufacturers worldwide are closely monitoring the situation as nickel is a crucial component in electric vehicle batteries.

Differing Accounts on Production Impact
GEM, the primary shareholder of QMB, responded to inquiries by stating that the observed production decrease was attributable to scheduled maintenance and national holidays, rather than being directly linked to the landslide incident. However, this explanation contrasts with reports from other sources within the industry.
Park Management Acknowledges Landslide, Denies Output Disruption
PT IMIP, the management entity responsible for the industrial park, has officially acknowledged the landslide and confirmed the casualties. Despite these acknowledgements, PT IMIP maintains that the incident has not resulted in any disruptions to overall nickel output. They attribute the landslide to unusually prolonged and intense rainfall in the region.
Industry Experts Voice Concerns Over HPAL Expansion
Nickel traders operating in Southeast Asia and China have expressed apprehension regarding the potential for recurring disruptions, particularly as the adoption of HPAL technology continues to expand. HPAL, while enabling the processing of lower-grade nickel ore, inherently produces significant quantities of waste, posing ongoing management challenges.
Indonesia’s Rapid HPAL Plant Growth
Indonesia has witnessed a rapid proliferation of HPAL plants in the past five years, with substantial investment and technical expertise originating from Chinese entities. This rapid expansion underscores the growing reliance on HPAL for nickel production.
Environmental and Safety Standard Re-evaluation
The increasing prevalence of HPAL plants, with their inherent waste management complexities, could reignite broader concerns regarding environmental protection and safety standards within Indonesia’s burgeoning nickel sector. Ensuring robust environmental safeguards and worker safety protocols is becoming increasingly critical as the industry expands.
Past Accidents Highlight Systemic Issues
Indonesia’s metals sector has experienced a series of accidents coinciding with the rapid growth of its nickel industry over the last decade. A particularly devastating smelter explosion in 2023 resulted in the loss of 21 lives, underscoring the need for improved safety measures.
Broader Industry Challenges
Putra Adhiguna, Managing Director at the Australia-based Energy Shift Institute, commented on the situation, stating, “These issues should not be regarded as isolated incidents confined to specific companies. They are indicative of a more pervasive industry-wide challenge,” suggesting systemic improvements are necessary.
PT IMIP Announces Measures to Enhance Safety Protocols
PT IMIP has publicly announced a series of measures aimed at enhancing safety standards and mitigating the risks of geological disasters. These measures reportedly include land reclamation initiatives, site levelling procedures, and reforestation efforts intended to stabilize the terrain and improve overall environmental resilience within the industrial park.
Uncertainty Remains Over Production Losses
Despite these announced mitigation efforts and safety enhancements, the full consequences and broader ramifications of the recent production losses at Morowali Industrial Park remain uncertain and are subject to ongoing assessment as investigations continue and the situation evolves.
Reduced Output Expected at QMB Amidst Investigation
QMB Output Impacted by Government Probe
Sources suggest that QMB, which counts Tsingshan Holding Group and Guangdong Brunp Recycling Technology among its shareholders, is anticipated to experience a reduction in output during April as a consequence of the government’s ongoing investigation into the landslide incident and associated safety concerns.
QMB’s Q1 Nickel Shipments
GEM’s statements indicate that the QMB plant shipped over 25,000 tonnes of nickel in the first quarter of the current year, highlighting its significant production capacity prior to the recent disruptions.
Mining Association Calls for Royalty Rate Reconsideration
Industry Concerns Over Rising Operational Costs
In March 2025, the Indonesian Mining Association urged the government to reconsider its proposed increase in royalty rates for mining products. The association cited escalating operational expenditures and constrained cash flows faced by mining operators, arguing that higher royalty rates could further strain the sector’s financial viability and competitiveness.
