Gold Refining Equipment Suppliers in Nigeria

Nigeria is buying gold refining equipment because its central bank now wants the finished bars. In March 2026, the Central Bank of Nigeria said its gold holdings had reached $3.5 billion, built from domestically mined gold refined to international standard, per PUNCH. That policy turns artisanal output into a buyer of furnaces, electrolytic cells, and assay kit. This guide maps where those RFQs sit and how a supplier wins them.

Why Nigeria is now a buyer of refining equipment

For years Nigeria dug gold and let it leave the country as unrefined doré, with the value-add happening elsewhere. Federal policy has changed that, and the change is what creates equipment demand.

The pivot is the National Gold Purchase Programme (NGPP). Gold is mined domestically, aggregated through the Solid Minerals Development Fund (SMDF), refined to London Bullion Market Association Good Delivery standard, and bought by the central bank in naira at prices benchmarked to the LBMA gold price. CBN Governor Olayemi Cardoso said the bank “purchased the gold in naira at prices linked to LBMA benchmarks,” growing reserves without spending scarce foreign currency, according to PUNCH. Fatima Shinkafi, Executive Secretary of the SMDF, said the delivery “demonstrated the strength of the fund’s formalisation framework.”

Read that as a procurement signal. A government committed to buying LBMA-grade bars off a domestic supply chain has committed, by extension, to the refining capacity behind them. You cannot deliver Good Delivery gold without melting furnaces, a Miller or Wohlwill line, fire-assay equipment, and the fume handling that makes the chemistry legal. Every tonne the CBN adds to reserves is a downstream pull on that kit.

You are reading this as an OEM, EPC, or trading house that makes or integrates gold refining equipment, deciding whether to chase Nigerian RFQs. Nigeria is the buyer, not a competitor. For the wider picture on FX, ports, and federal procurement, start with the Nigeria industrial and procurement landscape guide, and treat this as the gold-refining layer under the Nigeria mining and minerals sector map.

The refining route decides the equipment quote

A buyer does not ask for “gold refining equipment.” A buyer asks for a route to a target purity, and the route dictates the kit. Get this conversation right and you are quoting the correct line items before a competitor has understood the spec.

The Miller chlorination route. Chlorine gas is blown through molten gold; base-metal and silver impurities form chlorides that separate as slag or volatilise off. The LBMA describes it as fast and low cost, producing gold “with a fineness of 995 or 996” that casts straight into London Good Delivery bars. The limitation: Miller cannot separate platinum-group metals or reach four-nines. For a buyer whose doré is reasonably clean and whose target is the 995.0 LBMA minimum, it is the cheaper capital line. The equipment quote: induction melting furnaces, a chlorination reactor and gas-handling skid, slag handling, and bar casting.

The Wohlwill electrolytic route. A cast anode of impure gold dissolves in a hydrochloric-acid and gold-chloride electrolyte, and pure gold plates onto the cathode. This reaches 99.99% and beyond, the four-nines grades the investment and East Asian markets want, and recovers platinum-group metals into the electrolyte. The trade-off is capital intensity and a large gold inventory locked in the electrolyte. The quote adds electrolytic cells, rectifiers, anode casting, electrolyte management, and a PGM recovery train on top of the melting and assay base.

Most serious refiners run both: Miller as the workhorse to 995, Wohlwill where the customer pays for 999.9. A supplier who can scope the combined line, or supply the single sub-system a buyer’s plant is missing, is the one in the RFQ conversation. Underneath both routes sits the kit no one skips: induction melting furnaces, a fire-assay laboratory (cupellation furnaces, fluxes, certified reference materials, XRF or ICP screening), fume scrubbing and acid-fume extraction, and security-grade weighing and vaulting.

What LBMA Good Delivery actually demands

Nigerian refiners care about your equipment’s quality because the buyer of last resort, the central bank, will only take Good Delivery gold. According to the LBMA accreditation rules, a gold refiner applying to the Good Delivery List must have existed for at least five years, refined gold for not less than three, hold a tangible net worth of at least £15 million, and run an annual refining production of not less than 10 tonnes of gold. The fineness floor is 995.0 parts per thousand, with assays distributed across a panel of accredited referee laboratories for independent fire-assay verification.

Those thresholds matter commercially. They set the minimum plant scale and assay rigour a Nigerian buyer must design for, which is exactly the capacity and quality conversation you want to be having. The standard also explains the supplier-side reality: the world’s reference refiners sit in a handful of accredited hubs, with Switzerland alone refining around 70% of the world’s gold across four LBMA-accredited plants, the picture we cover in Swiss precious metal refining. Nigeria is building toward that standard from the other direction, as the buyer assembling the plant. That buyer-to-supplier axis is the opportunity.

Named buyers and the RFQ map

These are the entities that issue or back gold refining equipment RFQs in Nigeria.

Dukia Gold & Precious Metals Refining. The most advanced private refiner. Dukia is positioned as a full-service bullion merchant producing .9999 fine Good Delivery bars, and the Nigerian Investment Promotion Commission records it trading bullion through the Lagos Commodities and Futures Exchange. Dukia has stated that its phased refinery began with essential equipment “on order from pre-qualified world leading manufacturers,” the clearest signal in this market that the buyer imports refining plant from foreign OEMs. That is your entry line.

Kian Smith Trade & Co. The other licensed pioneer, with a refinery at Mowe in Ogun State. Per Mining.com, the plant was designed to start at 3 tonnes of gold a month and scale toward 10 over five years; Vice Chairman Nere Teriba called it “a five-year expansion plan to get to 10 tonnes a month of gold.” Timelines in this segment have moved unevenly, normal for first-of-kind builds in a new market, but the licensed ambition tells you the equipment scale a fully funded Nigerian refiner targets.

The Solid Minerals Development Fund (SMDF). As the NGPP aggregator and institutional anchor of formalisation, the SMDF sits upstream of capacity decisions. Where it underwrites processing capacity, specification passes through disciplined institutional procurement rather than one owner’s preference, the more open ground for a non-incumbent supplier.

Artisanal-to-industrial consolidators. Formalisation is pulling thousands of small-scale miners into traceable channels, and the consolidators who buy that output need entry and mid-tier capacity: smelting and assay furnaces, gravity concentration, electrowinning cells, and mercury-free processing. The NGPP follows the OECD Due Diligence Guidance and the World Gold Council’s London Principles, so clean, auditable, mercury-free kit has a regulatory tailwind. This is the recurring, smaller-ticket layer.

The Central Bank of Nigeria does not buy your furnaces, but as sole off-taker its appetite for Good Delivery gold underwrites every refiner’s capital case. Track its reserve announcements the way you would an end-customer’s order book, and map all three buyer layers rather than chasing one.

FX, duty, and payment mechanics for refining-plant deals

The commercial frame for gold refining equipment into Nigeria is more favourable than most foreign suppliers assume.

Import duty. The Nigerian Investment Promotion Commission confirms 0% import duty on equipment and machinery in the mineral mining sector under HS Headings 84, 85, and 90. A mineral-title holder importing melting furnaces, an electrolytic line, and assay equipment brings them in duty-free. Build that into your landed-cost story against locally fabricated alternatives.

FX and payment. The 2023 reforms unified Nigeria’s FX windows and lifted the 44-category import restriction, moving toward willing-buyer/willing-seller pricing. Gross external reserves reached $50.45 billion in early 2026, documented in the US Department of State 2025 Investment Climate Statement. FX scarcity for legitimate industrial imports is no longer the structural blocker it was; confirmation cost and the official-versus-parallel spread are the live variables. A gold refinery is a mid-ticket build, not a billion-dollar EPC, so payment usually runs through confirmed irrevocable LCs from Tier 1 Nigerian banks, with international confirmation out of London, Frankfurt, or Dubai. For a first export into Nigeria, quote against a confirmed LC at sight or 30 to 90 days and price the confirmation cost into the line items.

Because the CBN buys the finished gold in naira, the refiner’s revenue is partly naira-denominated against a dollar-priced capital import. That mismatch shapes how a refiner phases capex, which is why the duty-free position and flexible payment phasing are strong levers in your offer.

Conventional channels losing steam in Nigerian gold refining

The old way of selling refining equipment into a market like this is getting harder, and the cost math no longer favours it.

Mining and minerals trade fairs. Nigeria Mining Week in Abuja, run by the Miners Association of Nigeria with PwC Nigeria and the Vuka Group, is a real relationship-builder and drew more than 2,100 professionals in 2024. But a booth, freight, hospitality, and senior-engineer time runs $20,000 to $80,000 per event, and the buyer density for gold refining equipment specifically, against all the lithium, cement, and general mining traffic, is thin. Per-qualified-lead cost realistically lands at $300 to $900 or more, and it scales linearly.

Field sales representatives. A senior expat refining-equipment rep in Lagos, fully loaded with housing, schooling, hardship allowance, and security, runs $300,000 to $500,000 a year; a capable Nigerian sales engineer with real pyro- and hydro-metallurgical knowledge runs $80,000 to $150,000. Either way one rep covers a handful of accounts, and there are only a handful of serious refiners to cover. Per-qualified-lead cost ends up around $500 to $1,200 or more.

Distributor lock-in, trade missions, and print. Selling through a Lagos trading house adds margin and distance, and serious refiners increasingly prefer a direct OEM relationship with a local after-sales agent because refining plant lives or dies on spares response. Bilateral mining delegations open doors but rarely close purchase orders, and a refinery’s technical buyer does not source a Wohlwill cell or a cupellation furnace from a print advertisement.

None of these is dead. The problem is that none of them, alone, gives you parallel coverage across Dukia in Lagos, the Ogun-based capacity, the SMDF-anchored projects, and the consolidation buyers at once, at a cost that holds as the buyer set grows.

How papaverAI fits

The structural gap here is parallel coverage of a small, high-value buyer set at a sustainable cost. There are not hundreds of gold refiners in Nigeria, just a handful that matter and a growing tail of consolidators. A supplier who keeps quarterly contact with the procurement, plant-engineering, and project leads at every one wins more RFQs than one running hot on a single account. papaverAI’s outbound engine maps every relevant Nigerian buyer in your equipment line, drafts outreach grounded in real local context (the NGPP off-take, the LBMA Good Delivery target, the duty-free import position, the named refiners), and hands live replies to your team.

The cost lands at $150 to $300 per qualified lead, against $300 to $900 or more for a mining trade fair and $500 to $1,200 or more for a field rep. The difference that compounds is the cost curve: trade fairs and reps scale linearly, while the engine’s marginal cost falls as it runs.

FAQ

Who buys gold refining equipment in Nigeria? The named private refiners are Dukia Gold, producing .9999 Good Delivery bars and trading through the Lagos Commodities and Futures Exchange, and Kian Smith Trade in Ogun State, licensed for capacity scaling toward 10 tonnes of gold a month. Behind them sit Solid Minerals Development Fund-anchored capacity and a growing tail of artisanal-to-industrial consolidators who need smelting and assay equipment.

What gold refining equipment does Nigeria actually need? Induction melting furnaces, a Miller chlorination line for 995 to 996 fineness, a Wohlwill electrolytic line for 999.9 and platinum-group recovery, fire-assay laboratory equipment (cupellation furnaces, XRF or ICP screening, certified reference materials), fume scrubbing and acid-extraction, plus security-grade weighing and vaulting. Buyers targeting central-bank off-take need the assay rigour that proves LBMA Good Delivery fineness.

Why is Nigeria buying refining equipment now? The Central Bank of Nigeria built gold reserves to $3.5 billion by March 2026 under the National Gold Purchase Programme, buying domestically mined gold refined to LBMA Good Delivery standard in naira rather than foreign currency. That off-take commitment underwrites domestic refining capacity, which pulls demand for refining plant.

What is the difference between Miller and Wohlwill refining for a buyer’s equipment spec? The Miller chlorination process is fast and low cost and produces 995 to 996 fineness, enough for London Good Delivery, but cannot separate platinum-group metals or reach four-nines. The Wohlwill electrolytic process reaches 99.99% and beyond and recovers platinum-group metals, at higher capital cost and with a large gold inventory locked in the electrolyte. Most serious refiners run both, which changes the equipment line items you quote.
