Tanzania Nickel Hydromet Refinery Equipment (2026)

Tanzania’s only large-scale nickel refinery sits behind the Kabanga project, which carries a USD 1.58 billion after-tax NPV at a 23.3% IRR in Lifezone Metals’ July 2025 feasibility study, with a final investment decision targeted for 2026. The refinery uses a hydrometallurgical flowsheet rather than a smelter, so the equipment scope is autoclaves, pressure-leach trains, solvent extraction, electrowinning, and metal-salt precipitation.

What the Kabanga refinery actually buys

Kabanga is the headline base-metals story in Tanzania’s mining and minerals sector, and the refinery is the part of it that pulls the most specialised process equipment. Lifezone is building to a hydromet route at Kahama instead of shipping concentrate to a third-party smelter abroad, which is the whole commercial logic of the project: refine in-country, capture the value, and supply nickel suitable for battery and stainless markets.

Almost none of that machinery is built in Tanzania. The US trade.gov country commercial guide states plainly that “the mining sector depends on imported machinery and supplies,” so a refinery package this size is an import play start to finish.

That choice sets the equipment list. A hydromet nickel refinery is not a furnace shop. The core packages are:

Pressure leaching. Titanium-clad or duplex autoclaves running high-pressure acid or oxidative leach, with the associated heat exchangers, flash vessels, and slurry let-down systems. This is the single most engineering-heavy package and the one with the fewest qualified global vendors.

Solid-liquid separation. Counter-current decantation thickeners, pressure and vacuum filters, and the pumps and slurry-handling lines that move pregnant leach solution through the circuit without eating themselves alive on abrasion and acid.

Solvent extraction and electrowinning (SX-EW). Mixer-settler trains, organic-reagent handling, and electrowinning cellhouses for copper and, where the flowsheet calls for it, cobalt and nickel cathode or sulphate production.

Metal-salt precipitation. Mixed hydroxide or mixed sulphide precipitation (MHP/MSP) reactors, plus the crystallisation and drying packages that turn intermediate streams into a saleable nickel and cobalt product. Lifezone has signalled it may target sulphate or powder end products to trim upfront capital and match market demand, which shifts the back-end package mix.

Reagent, utilities, and instrumentation. Acid plants or acid handling, oxygen supply, steam, process water and effluent treatment, and the distributed control system that ties the flowsheet together.

For the country-wide picture on how this fits the wider procurement pipeline, the Tanzania industrial and procurement guide maps the FX, TANePS, and mega-project context that every Kabanga package runs through.

Who issues the RFQ

The buyer is Lifezone Metals, which holds the special mining licence and controls the project. The company has confirmed a staged build: mine and concentrator first, with the Tanzanian refinery to follow. That sequencing matters for suppliers. Concentrator and materials-handling packages are the near-term window, and the refinery hydromet packages open behind them, so a refinery-equipment vendor is positioning now for procurement that lands after the concentrator is committed.

The other reality is that Lifezone will not buy autoclaves and filter presses line by line off its own desk. Post-FID, a project this size runs through an EPCM contractor who owns the flowsheet and awards the equipment packages. On regional base-metals and hydromet work the recurring process-engineering names are Lycopodium, DRA Global, Fluor, and Hatch, alongside Lifezone’s own technical team carrying the Hydromet Technology know-how. The supplier who maps which EPCM holds the Kabanga flowsheet, then gets a pressure-leach autoclave or an SX train onto that contractor’s vendor list before the package tenders, is the supplier who gets shortlisted.

Lifezone’s COO Gerick Mouton noted in the company’s December 2025 update that the teams are “advancing early works, including geotechnical drilling and site preparation, while procurement and logistics planning are well underway,” per Lifezone’s investor release. Procurement planning that early is the signal for vendors to engage the EPCM, not wait for a published tender.

FX, letters of credit, and the development-finance layer

Tanzania reclassified the shilling to a floating regime in November 2024 under its IMF program, and the TZS appreciated roughly 9.5% against the dollar over the following year on the back of record gold receipts. For a refinery-equipment supplier, that means USD availability is materially better than it was in 2023, though high-import quarters still bring periodic tightness. Plan deals on confirmed letters of credit, not open account.

The settlement pattern for a package this size is a confirmed LC, with confirmation by a Tier 1 European or Gulf bank standard above USD 5 million. The Tanzanian confirming banks are CRDB, NMB, NBC, Stanbic, and Standard Chartered Tanzania. Budget 30 to 60 days of LC processing into your lead time and price 10% retention until commissioning into your cash flow, because that is normal on plant-scale orders.

Kabanga adds a layer most Tanzanian deals do not have: development finance. The project’s financing process has drawn engagement from the US International Development Finance Corporation (DFC), which completed its environmental and social due diligence, and from Japan’s JOGMEC, alongside a USD 60 million bridge facility from Taurus Mining Finance closed in September 2025, per the Lifezone financing announcement. Where DFC or other development-finance money sits behind a package, suppliers can find procurement terms, content rules, and reporting attached that come from the financing institution rather than the buyer. Read the financing structure before you quote, because it changes the documentation and the timeline.

The broader US-Tanzania interest in the project is itself a market signal: the Northern Miner reports Washington and Dodoma deepening talks on political-risk backing and project finance, framed around securing nickel supply outside concentrated chains. For an equipment vendor, that lowers perceived offtake and political risk on a project that would otherwise read as a single-buyer bet.

How the equipment landscape splits by supplier country

Pressure-leach autoclave technology has a short vendor bench worldwide, concentrated in a handful of process licensors and pressure-vessel fabricators across Europe, North America, and a small number of specialist Asian shops. Filtration, thickening, pumps, and mixer-settlers have a wider field. US, German, Finnish, and Australian process-equipment houses all compete on hydromet packages, and Chinese EPC-plus-financing bids press hard on integrated plants. Non-Chinese suppliers tend to win on specific engineering fit, recovery performance, materials selection for acid and abrasion service, and after-sales depth, bid through the EPCM rather than on headline price.

The US is a deep bench for mineral-processing and mining equipment, and the supplier-side view of that market, including how US OEMs reach overseas mine and refinery buyers, sits in our companion guide on US mining equipment exporters. It is the mirror image of this page: the same equipment family read from the supplier’s side of the table rather than the Tanzanian buyer’s.

Dying conventional channels for refinery equipment

The traditional routes into a project like Kabanga are losing ROI fast. They are not dead, but the cost-per-qualified-lead math has moved.

Mining and processing expos. The rotating East and Central Africa mining events and the larger continental shows such as the Investing in African Mining circuit still produce a few conversations, but for a refinery-equipment OEM the qualified-lead count is thin and the fully loaded cost per lead lands in the USD 400 to USD 900 range once booth, freight, travel, and follow-up are counted. The procurement engineers who actually scope an autoclave package rarely walk a trade-fair floor to find a vendor.

Expatriate field representatives. A Dar or Mwanza-based technical sales rep with hydromet sector knowledge runs USD 5,500 to USD 11,000 a month all-in once salary, housing, work permit, vehicle, and expenses are loaded. At a realistic three to six qualified leads a month, that is roughly USD 900 to USD 3,700 per qualified lead, and the economics only clear above EUR 5 million in annual Tanzanian revenue. For a single-project, multi-year refinery pursuit, a full-time rep is hard to justify.

Distributor and trading-house lock-in. The legacy mechanical-aftermarket houses take 15 to 30% margin and rarely run active outbound. A specialised autoclave, filter, or SX vendor sits invisible inside a generalist catalogue, which is the opposite of what an EPCM vendor-qualification process rewards. Tanzanian buyers increasingly want direct OEM engineering contact and keep distributors for spares logistics.

Embassy trade missions and print trade press. German GTAI, US commercial-service, and other national missions generate introductions, not pipeline. Tanzanian procurement engineers scoping a refinery package read TANePS notices, EPCM vendor portals, and English-language search results, not print sector magazines.

How suppliers reach the Kabanga refinery procurement

Government-linked Tanzanian tenders surface on TANePS, the national e-procurement portal, and that is where any state-side mining work appears. But Kabanga is a private project, so the real gate is Lifezone’s own vendor-registration process and, after FID, the EPCM contractor’s approved-vendor list. The playbook is: register interest with Lifezone, identify the EPCM as soon as it is appointed, and get your hydromet package onto that contractor’s vendor list with a technical reference that proves acid-service and pressure-leach experience. English is the working language for all of it.

FAQ

What equipment does a nickel hydromet refinery need?

A hydromet nickel refinery buys pressure-leach autoclaves, heat exchangers and flash vessels, counter-current decantation thickeners, pressure and vacuum filters, solvent-extraction mixer-settlers, electrowinning cells, and mixed hydroxide or sulphide precipitation reactors, plus acid handling, oxygen supply, effluent treatment, and a distributed control system.

When does Kabanga refinery procurement open?

Lifezone is staging the build, with the mine and concentrator first and the Tanzanian refinery to follow. With a final investment decision targeted for 2026, concentrator packages are the near-term window and refinery hydromet procurement opens behind them, so refinery vendors position with the EPCM well ahead of the published tender.

Who buys the Kabanga refinery equipment?

Lifezone Metals holds the licence and controls the project, but post-FID the equipment packages are awarded by the EPCM contractor that owns the flowsheet. Regional process-engineering names include Lycopodium, DRA Global, Fluor, and Hatch. Suppliers should target that contractor’s vendor list, not only Lifezone directly.

How are payments handled for refinery equipment sales to Tanzania?

Confirmed letters of credit are standard, with Tier 1 European or Gulf bank confirmation above USD 5 million. CRDB, NMB, and Standard Chartered Tanzania are the main local confirming banks. Budget 30 to 60 days for LC processing, expect 10% retention until commissioning, and check whether DFC or other development-finance terms attach to the package.

Why a hydromet refinery instead of a smelter?

Lifezone’s hydrometallurgical route refines nickel, copper, and cobalt in-country with lower energy use and emissions than conventional smelting, and produces battery-grade and stainless-suitable products. The choice keeps refining value in Tanzania and shapes the equipment list around pressure leaching and solvent extraction rather than furnaces.
