• Zimbabwe is assessing the applicability of Indonesia’s Weda Bay industrial park after a government benchmarking visit
• Zimbabwe has moved further into steel, lithium and chrome processing, but much of the industrial architecture remains project-specific
• Weda Bay raises the benchmark from processing minerals locally to building power, logistics, suppliers and downstream manufacturing around them

Harare - Zimbabwe is assessing whether the industrial model behind Indonesia’s Weda Bay complex can be replicated locally as the country attempts to move its mineral beneficiation strategy beyond individual processing plants towards integrated industrial production.

A government delegation visited the Indonesia Weda Bay Industrial Park between 28 July and 3 August to benchmark the model and assess its applicability to Zimbabwe. Cabinet said the complex generates approximately US$13 billion in annual industrial output, with its development supported by policies that pushed mineral processing and downstream manufacturing into Indonesia. Government now intends to draw from the model under a phased Industrial Park Development Framework.

‘’ The objective of the Visit was to benchmark the Tsingshan-led Industrial Park model and assess its applicability in Zimbabwe, in terms of leveraging the country’s mineral resources as a catalyst for mineral beneficiation, industrialisation, export growth and economic transformation,’’ Cabinet said in its 28th post-Cabinet briefing.

Weda Bay is a large nickel mining and industrial complex on Halmahera Island in Indonesia’s North Maluku province. The underlying nickel project dates back several decades, with French mining group Eramet acquiring Weda Bay Minerals in 2006 before partnering Chinese metals group Tsingshan in 2017. Mining started in late 2019 and the first nickel ferroalloy plant entered production in 2020. Indonesia’s state-owned mining company Antam also holds an interest in the mining operation.

The mine sits within the wider Indonesia Weda Bay Industrial Park, where the economic model extends beyond extraction. Nickel ore feeds metallurgical plants located close to the resource, while the coastal industrial park provides electricity generation, processing facilities and direct port access. By the end of 2023, the complex hosted 17 nickel pig iron plants and a high-pressure acid leach facility alongside other metallurgical operations. Higher-grade nickel feeds ferroalloy production used principally in stainless steel, while lower-grade ore can enter processing routes producing intermediate material for battery supply chains.

That industrial concentration is the part of Weda Bay most relevant to Zimbabwe. The mine provides feedstock, processing plants convert the mineral locally, dedicated infrastructure supports production and additional industries develop around the intermediate products. Mineral extraction becomes the starting point for an industrial system rather than the final export activity.

Indonesia created the conditions for that development through an aggressive downstreaming policy. Restrictions on unprocessed nickel exports forced miners towards domestic processing, while Chinese capital and technology supplied much of the investment required to build smelters and industrial parks. Indonesia subsequently moved from a relatively small participant in global nickel processing to the dominant producer. Its share of global refined nickel supply increased from about 6% in 2015 to approximately 65% in 2025.

Zimbabwe has been moving in the same policy direction, although from a considerably earlier stage of industrial development.

The country restricted exports of unbeneficiated lithium ore in 2022 and has progressively tightened processing requirements. Government has since adopted a broader minerals value-chain framework built around mandatory minimum processing standards, while lithium concentrate exports face an intended ban from January 2027. The policy objective is to retain more processing activity before minerals leave the country.

Lithium provides the clearest evidence that the policy has begun moving capital downstream. Chinese mining companies have invested about US$2 billion in Zimbabwe’s lithium sector since 2021, although the country still exported approximately 1.13 million tonnes of spodumene concentrate to China in 2025. Huayou Cobalt subsequently commissioned a US$400 million lithium sulphate plant with annual capacity of 50,000 tonnes and made Zimbabwe’s first lithium sulphate export in April 2026. Other producers are developing similar processing facilities.

That is material progress from exporting unprocessed ore. It is still several stages removed from a complete battery value chain.

Lithium sulphate remains an intermediate product that undergoes further refining before becoming lithium chemicals and eventually battery materials. Zimbabwe has therefore captured another processing stage without yet creating the broader manufacturing ecosystem that converts its lithium resource into cathode materials, cells or finished batteries.

Steel presents a more advanced industrial case.

Tsingshan’s Dinson Iron and Steel Company has established integrated steel production at Manhize, restoring large-scale primary steelmaking after the collapse of Ziscosteel. Current output is around 600,000 tonnes annually, and management is considering raising capacity to as much as 2 million tonnes. About 40% of existing production is sold locally, with the remainder exported mainly to South Africa and smaller regional markets including Zambia and Malawi.

Manhize already integrates more of its production chain than many of Zimbabwe’s mineral projects. Iron ore is mined domestically, metallurgical inputs feed the steel operation and the company is developing additional products around the complex. Its planned expansion is therefore one of the closest existing Zimbabwean examples to the industrial logic Government observed in Indonesia.

The constraints emerging at Manhize also demonstrate why Weda Bay cannot simply be copied.

Dinson has identified rail infrastructure as necessary for its next expansion and is discussing a potential rail joint venture with Mutapa Investment Fund. Increasing steel output from 600,000 tonnes towards 2 million tonnes changes the amount of ore, coal and finished product that must move through the economy. Production capacity can expand faster than the infrastructure required to carry its inputs and output.

The same problem becomes larger under an industrial park model. Smelters, chemical plants and heavy manufacturers require dependable baseload electricity. Bulk commodities require rail and port capacity. Water systems must support industrial consumption. Downstream manufacturers require serviced land, finance and access to domestic or export markets.

Zimbabwe has made stronger progress in attracting processing capital than in building that shared industrial infrastructure.

Its current beneficiation programme remains largely organised around individual investors solving their own constraints. Large mining and industrial companies develop processing plants, captive electricity solutions, water infrastructure or transport arrangements around their projects. That can make individual investments viable, but it does not automatically create an industrial ecosystem available to the next manufacturer.

Weda Bay reverses that relationship. Shared infrastructure allows multiple processing and manufacturing operations to cluster around the mineral resource. The value of the original mine is then extended by the number of additional productive activities that can operate around it.

Zimbabwe’s next industrialisation phase therefore requires a different measurement from the number of beneficiation plants commissioned.

The first test is whether processing investments generate domestic industrial linkages. A lithium sulphate plant creates more domestic value than exporting spodumene concentrate. Its wider contribution increases further when local engineering companies maintain the plant, domestic chemical suppliers enter the production chain and additional manufacturers use its output as an input.

Steel provides similar possibilities. Higher Manhize production creates greater value when locally produced steel feeds domestic fabrication, engineering, construction materials and machinery production. Exporting the additional steel still generates foreign currency, but deeper domestic conversion creates another layer of industrial activity from the same mineral base.

Zimbabwe has therefore advanced further than its historical extract-and-export structure, although the progress remains uneven.

The lithium export restrictions have forced investment into processing. Huayou’s lithium sulphate plant establishes that policy pressure can move part of the value chain onshore. Manhize demonstrates that large-scale mineral processing and manufacturing can be established locally. Ferrochrome provides another established beneficiation industry. Government’s latest minerals framework extends the same policy direction across a broader range of commodities.

Execution has also exposed the limits of using regulation alone. Lithium producers are already seeking more time to meet the January 2027 concentrate export deadline. Only Huayou currently has an operational lithium sulphate plant, while other major producers remain at various stages of construction or feasibility work. Producers have cited capital requirements, operating costs and policy uncertainty among the difficulties surrounding the transition.

That experience carries an important lesson from Indonesia. Export restrictions created the incentive to process nickel domestically, but the transformation required enormous amounts of external capital, proven processing technology, infrastructure and a large investor capable of executing at scale. The prohibition on raw exports created the commercial requirement. It did not build the industrial system by itself.

Zimbabwe's relationship with Tsingshan makes the Weda Bay benchmarking exercise particularly relevant. The same industrial group that helped build Indonesia’s nickel processing ecosystem already controls one of Zimbabwe’s largest new industrial investments at Manhize. The country is therefore not studying a model completely detached from its existing investor base.

The larger question is whether that relationship can produce broader domestic industrial capacity rather than a collection of successful foreign-owned processing assets.

Indonesia's experience also provides reasons for caution. Its rapid nickel expansion contributed to global oversupply severe enough to depress prices and force higher-cost producers elsewhere to close. Jakarta is now reducing production quotas, including at Weda Bay, as it attempts to manage supply and support nickel prices. Weda Bay's 2026 mining quota was initially cut sharply from the previous year's authorised level.

Industrial scale therefore does not remove commodity exposure. It can magnify it when capacity expands faster than final demand.

Environmental and labour performance create another part of the benchmark. Indonesia’s nickel industrialisation has faced scrutiny over coal-intensive electricity, environmental damage and workplace safety. Zimbabwe would weaken the long-term competitiveness of its own mineral processing if industrial expansion reproduced those costs, particularly as battery and critical-mineral buyers increasingly scrutinise carbon intensity and supply-chain standards.

The Weda Bay lesson is consequently broader than beneficiation. Zimbabwe has already demonstrated that it can compel more processing and attract capital into mineral projects. The next stage requires converting those investments into industrial networks capable of supporting additional businesses. Power, rail, water and industrial land need to become shared productive infrastructure. Processing outputs need downstream buyers. Domestic suppliers need access to procurement chains. Skills and technology need to remain in the economy beyond the construction phase.

Cabinet's proposed phased Industrial Park Development Framework provides the institutional vehicle for that transition. Its performance will ultimately be measurable through investment and production rather than the number of parks designated.

Zimbabwe does not need to reproduce Weda Bay physically. Nickel gave Indonesia one industrial pathway. Zimbabwe has a different mineral combination spanning lithium, chrome, iron ore, platinum group metals and gold. The useful part of the Indonesian model is the organisation of those resources around infrastructure and downstream production.

Zimbabwe's beneficiation record is therefore no longer empty. Lithium processing has moved forward, Manhize has restored integrated steelmaking and ferrochrome remains an established processing industry. The weakness lies in the space between those investments. Rail remains constrained, electricity remains a major industrial cost and much of the downstream manufacturing capacity needed to consume intermediate products locally is still shallow.

Weda Bay raises the benchmark. Processing a mineral before export captures one additional stage of value. Building an industrial system around that mineral creates repeated stages of investment, production and employment from the same resource base.

Zimbabwe has started the first transition. The US$13 billion Indonesian complex Government has chosen to study shows the scale of the second. Whether Zimbabwe reaches it will depend less on another beneficiation directive and more on whether the country can connect the processing plants it is already attracting to dependable infrastructure, downstream manufacturers and domestic suppliers capable of turning mineral wealth into a broader industrial economy.
