Asia's Technological Leap in Nickel-Cobalt Refining

Metals and Mining Review | Monday, August 25, 2025

Fremont, CA: Asia has become a central force in the nickel and cobalt processing industries, driven by its vast mineral reserves, strategic government policies, and significant investments, particularly from China. This dominance is reshaping global supply chains and driving technological advancements, particularly in the field of electric vehicle (EV) batteries.

Dominance in Nickel Production and Processing

Asia’s growing influence in the global battery materials market is primarily driven by Indonesia and the Philippines, which together account for a significant share of the world’s nickel and cobalt reserves. Indonesia, in particular, has emerged as the world’s largest producer of nickel and has strategically shifted its policies to maximize value creation. By banning the export of unprocessed nickel ore, the country has successfully attracted substantial foreign investment—primarily from China—into the development of domestic smelting and processing facilities. This has given rise to large-scale industrial hubs such as the Morowali Industrial Park, which play a pivotal role in producing higher-value products, including ferronickel for stainless steel and mixed hydroxide precipitate (MHP) for electric vehicle batteries.

China, despite holding relatively modest nickel reserves, dominates the refining and processing segment of the supply chain. Chinese companies have invested tens of billions of dollars in Indonesian nickel projects, bringing in both capital and advanced technology to establish large-scale processing plants. This symbiotic partnership not only strengthens Indonesia’s position as a critical supplier of processed nickel but also secures a steady flow of battery-grade nickel and cobalt for China’s rapidly expanding electric vehicle and battery manufacturing industries.

The Future Landscape

Asia’s role in the global nickel-cobalt landscape is poised to expand as demand for electric vehicles (EVs) and renewable energy storage systems accelerates. While Indonesia and China currently dominate the supply chain, other nations, such as India, are actively working to secure critical mineral resources through international partnerships. India has already established agreements with resource-rich countries, including Australia and those within the Lithium Triangle—Argentina, Chile, and Bolivia—in an effort to reduce dependency and strengthen domestic processing capabilities.

This concentration of supply chain power in Asia also carries significant geopolitical and economic implications. With much of the world reliant on Asian processing, the region holds considerable leverage, while the lack of diversification exposes the global economy to strategic vulnerabilities. In response, Western nations and their allies are intensifying efforts to diversify sourcing and invest in domestic processing to build greater supply chain resilience.

Technological innovation and sustainability considerations will shape the evolution of nickel-cobalt processing in Asia. Advancements in high-pressure acid leaching (HPAL) and other refining methods, alongside the development of new technologies that minimize environmental and social impacts, will be central to future progress. Moreover, the integration of Environmental, Social, and Governance (ESG) standards is becoming increasingly critical, not only for attracting responsible investment but also for ensuring the long-term viability of the industry.

Asia's preeminence in nickel and cobalt processing transcends mere supply chain considerations; it stands as a testament to the continent's strategic foresight and a pivotal determinant in the global energy transition. By asserting control over the refinement of these indispensable battery minerals, Asia, particularly Indonesia and China, has strategically positioned itself, leveraging HPAL technology, as the electric vehicle revolution unfolds. The persistent trajectory toward hydrometallurgical technologies, such as HPAL, coupled with a burgeoning emphasis on sustainable methodologies and circular economy paradigms, will delineate the future trajectory of the industry. While this concentration of influence poses significant geopolitical ramifications for the global community, it also impels all stakeholders to innovate and cultivate more resilient, ecologically conscious supply chains. Ultimately, Asia's sustained role in shaping these technologies will be instrumental in determining the pace and effectiveness of the world's transition to a more environmentally sustainable future.

The Rt. Hon Dominic Raab, in partnership with the World Gold Council, today publishes a new report examining the systemic threats from the illicit trade of gold through artisanal and small-scale gold mining (ASGM). The Silence is Golden report finds the ASGM industry, responsible for an estimated 20% of annual gold supply and about 80% of gold mining employment1 , is being targeted by criminal gangs, armed groups and corrupt officials, presenting a real and present danger to international security. The report notes the top fundamental challenges that plague ASGM are: 1) The lack of transparency across businesses and governments for implementation and compliance with legal standards. 2) Failures of accountability creating serious breaches of national law and international obligations, allowing criminals to operate freely. 3) Criminals extracting enormous profits from serious human rights abuses, due to disconnected enforcement and compliance efforts across nations and international agencies. In response, it outlines four strategic objectives with 24 practical actions for governments, international organisations, NGOs, mining companies and economic development organisations. These include prosecuting and disrupting criminal perpetrators and sustaining a coordinated and focused international effort across G7 and G20 countries to tackle these pervasive issues. “Governments, international organisations and the gold sector must work together to prosecute criminals, prevent illicit profiteering and integrate responsible ASGM into the legal and viable supply chain,” said Rt. Hon Dominic Raab, former Deputy Prime Minister of the United Kingdom, the report’s author. “It will now require coordinated and sustained international attention and action to prevent the illicit flows from gold from bankrolling the war in Ukraine and enabling Al Qaeda and Islamic State to regroup in Africa.” “Without viable economic alternatives, the poorest and most marginalised of our world’s citizens are forced into artisanal gold mining, taking place within hazardous conditions and of little economic gain for their families,” said David Tait, CEO, World Gold Council. “Our partnership with Dominic Raab is a call to action to both redirect illicit gold away from the world’s bad actors and improve the lives of those working in the sector, offering actionable ways that governments and international 1 Please note these statistics are estimated and sourced from ‘Global Trends in Artisanal and Small-Scale Mining, A Review of Key Numbers and Issues’, Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development, 2017. agencies can contribute to positive change, both environmental and economic for the millions impacted globally.” ASGM, as defined in the report, is gold mining conducted by individuals or small enterprises with limited capital investment and production. While this practice spans 80 countries, it is particularly focused in Africa, Asia and Latin America. The majority of ASGM operates outside of formal legal frameworks, within the shadow economy, making it especially susceptible to serious risks and challenges including evasion of tax revenue for governments, lack of basic safety standards that can cause mercury poisoning and other maladies, and safety concerns for the miners and their communities.

Smart mines are still relatively new, although they are becoming more prevalent. This results from the mining industry's many barriers to implementing new technology. On the one hand, mines are competitive and segregated inside the company, which means they compete in terms of safety, production, and other aspects. Implementing new technology is hampered by internal politics and a lack of collaboration inside mining companies. All departments must work together to support integration and systems innovation. Every mine must be convinced of the need for new technology as they are distinct and competitive. Furthermore, because they typically take a very cautious stance about their data, mining operators frequently have little faith in cloud services and IoT solutions. This results from the industry's general mistrust of emerging technology and bad prior experiences with big, "reliable" businesses that have, for instance, been involved in hacking scandals. As others who take the risk start to gain from digitization, these obstacles make many mines less competitive and more expensive. Let’s quickly examine the advantages of making the mine digital: Reduce Operational Costs: Compared to their "analog" counterparts, "smart mines" with wireless monitoring have substantially lower operating expenses. In essence, smart mines are ones whose primary resources are digitalized using embedded sensors that transmit data over a wireless network to a central system. Because there is no longer a need for labor-intensive manual data readings on the ground, mining operators can save money on both human labor and costly cabling and subsequent cable maintenance. Not only do mines save money by eliminating these pointless expenses, but they also save a significant amount of money because operators who integrate an Operational Intelligence (OI) solution into their wireless network are more adept at anticipating problems and maintaining their sites regularly. These incidents can completely stop operations for weeks or months at a time. As a result, smart miners outperform regular mines in terms of ROI. Automate Processes More Readily: Automation of operations is easier for smart mines with integrated technologies than for those that implement technology later. By adding automation software, mining operators can enhance their current wireless network of embedded sensors. This software enables them to operate moving and static assets and programs remotely with automated interactions. An excellent illustration of this is the use of a physical network of sensors and remotely programmed and controlled software by automated trucks, enabling them to do mining tasks that previously required a fleet of truck drivers autonomously.  Keep the Workforce Safe: Regarding mines, which are frequently extremely dangerous locations for humans, worker safety is a big concern. For example, workers and nearby residents may suffer injuries or even die when dams fail. Employees performing manual readings in isolated or difficult-to-reach locations are more prone to injury. Workforce safety is significantly increased when movable assets, such as trucks in mines, are automated and wireless; remote readings are made possible. This eliminates the need for workers to be present on-site. Through OI technologies, mining operators can also benefit from predictive analysis and insights that help them better anticipate and avert potentially disastrous events like dam failure. Wearable technology that is wirelessly connected and enables workforce tracking aids in improving labor coordination for operators.  These are some of the benefits of digitalizing the mine. Even if there are numerous obstacles in the way of mines implementing new technology, these must be removed if mining firms are to succeed and stay competitive in the increasingly digital era.  ...Read more
