Namibia SX-EW Leaching Plant: Project Guide (2026)

If you build SX-EW and leaching plants and want a project in Namibia, the live anchor is Tschudi. Consolidated Copper describes it as an open-pit heap-leach SX/EW operation, built in 2015, with a production capacity of 17,000 tonnes a year of copper cathode, and it is the only plant in the country producing LME Grade A copper cathode. A second copper restart is funding the next wave of leach and hydromet demand.

What an SX-EW Leaching Plant Actually Involves

A buyer searching for SX-EW leaching plant suppliers in Namibia is usually scoping a copper or base-metal hydrometallurgy project, not a flotation concentrator. The flowsheet has five blocks, and you quote against the blocks, not the headline tonnage.

Leach. Oxidised copper ore goes through heap leach pads, or agitated tanks for finer material. Tschudi uses the heap route. Scope: liner systems, drip irrigation, raffinate and pregnant-leach-solution (PLS) ponds, stacking equipment, and sulphuric-acid handling. A chloride flowsheet like Omitiomire’s adds salt dosing and chloride-resistant materials.

Counter-current decantation (CCD). Where ore is leached in tanks rather than on a pad, a CCD thickener train washes the solids and recovers dissolved copper into solution. This is the high-tonnage thickener and pumping scope, where most of the steel sits.

Solvent extraction (SX). Mixer-settler trains move copper from the aqueous PLS into an organic phase, then strip it back into a clean, concentrated electrolyte. This is the heart of the plant and the part with the most vendor differentiation: settler design, organic-reagent handling, dual-media filters, and crud treatment.

Electrowinning (EW). The cellhouse plates copper out of the strip electrolyte onto cathodes. Scope covers the cells, rectifier and busbar, cell construction, a robotic cathode-stripping machine, and an acid-mist capture system. This block defines whether you hit LME Grade A.

Balance of plant. Reagent storage, acid receival, raffinate return, power supply, water (in Namibia, almost always desalinated or piped), and the control system.

Quote the block where your reference list is strongest. A pad-liner specialist, a thickener OEM, an SX mixer-settler licensor, and an EW cellhouse integrator are four different conversations, and the EPC tenders them separately.

The Verified Demand: Who Is Buying

The Namibian copper picture is small, named, and restarting. That is good for a supplier, because you can map the entire buyer list in a morning.

Tschudi (Consolidated Copper Corporation). LME Grade A copper cathode was produced at Tschudi for the first time in four years on 22 August 2024, restarting Namibia’s only LME-grade refined-copper facility. The plant produced over 80 kilotonnes of cathode up to 2020 before care and maintenance, and the restart was funded by a USD 20 million secured debt facility, more than 75% of the first-phase budget spent locally. Heap rehabilitation, debottlenecking, reagent supply, and cellhouse maintenance are the near-term scopes.

Central Operations (Otjihase and Matchless). CCC is running feasibility work to restart the Otjihase and Matchless underground copper mines, which sit in care and maintenance. These are sulphide ores headed for concentrate rather than cathode, but the restart pulls process plant, dewatering, and reagent demand into the same buyer.

Omitiomire (Omico Mining / Craton Mining and Exploration). The greenfield copper development in the interior belt. Its planned route is a chloride leaching process using salt and sulphuric acid, paired with solvent extraction and electrowinning to refine the copper to pure cathode. A chloride-SX-EW flowsheet is a different specification from Tschudi’s acid heap leach, and it is the one greenfield where a full new plant package is in play.

Namibia imports around USD 749 million of machinery and boilers a year, almost none of it made locally, so every component of a leach plant is a cross-border purchase. The broader operator list across diamonds, gold, and tin sits in our Namibia mining equipment guide.

Budgeting an SX-EW Project: Indicative Ranges

There is no published capex for the Namibian copper restarts, so treat the following as indicative engineering benchmarks from comparable projects, not as a quote, to scope the order of magnitude before you tender.

The clearest recent reference price for the SX-EW island is Metso’s Q1 2026 award on the Tia Maria project in Peru. Metso booked an EUR 100 million contract to supply VSF SX-EW plants for 120,000 tonnes a year of LME Grade A copper cathode, including dual media filters, a robotic cathode-stripping machine, and an acid-mist capture system. That is the technology scope for a large greenfield cathode line, and it scales down roughly with capacity toward a Tschudi-sized 17,000 tonne plant.

The split across the plant matters when you decide which block to bid. Engineering cost references such as 911 Metallurgist’s SX-EW cost work put the electrowinning tankhouse alone in the order of USD 945 per annual tonne of installed cathode capacity for a mid-sized case, with the SX circuit a similar block and the leach pad a third. So the leach pad, the SX trains, and the EW cellhouse are each a quarter to a third of plant capex, and a single-block supplier is bidding a fraction of the package.

Two Namibia-specific cost drivers sit on top of the equipment. Water is scarce and often desalinated, so raffinate recycling and water-balance design carry more weight than they would in Chile or Zambia. Power feeds off the NamPower grid or a project IPP, and the cellhouse is a continuous, power-hungry load. Both belong in the budget from day one.

How Namibian Copper Deals Get Paid

The currency setup is the quiet reason Namibia is an easier copper market than its neighbours. The Namibian dollar is pegged 1:1 to the South African rand under the Common Monetary Area, and Namibia is a SACU member, so there is no separate FX queue, no parallel-market premium, and no scarcity allocation to wait out. Copper cathode and concentrate sell into hard-currency export markets, so the buyer’s revenue line is matched to the dollars or euros you want to be paid in.

For a plant package, the standard route is a sight or deferred letter of credit issued by the buyer’s Namibian bank, Bank Windhoek, FNB Namibia, Standard Bank Namibia, or Nedbank Namibia, confirmed by a London, Frankfurt, or Johannesburg counterparty. Milestone-linked payment against engineering, manufacture, delivery, and commissioning is normal, with retention against performance acceptance. Export credit agency cover (Euler Hermes, SACE, UKEF, EXIM, Sinosure) is routinely available on Namibian mining buyer risk and is a real lever on tenor against an incumbent that already has the trade-finance plumbing built. Fixed-price packages tendered a year before delivery should carry commodity-indexed price-adjustment clauses on steel and copper. The full payment mechanics sit in the Namibia industrial and procurement guide.

EPC, Tender Routes, and Who Specifies the Plant

A leach or SX-EW package gets bought through the operator’s own engineering team or through the EPCM contractor running the build. The credible processing-plant engineering names active across Namibia and the wider southern African belt include DRA Global, Lycopodium, and the South African EPCM houses, with consultancies like SRK Consulting and Knight Piesold setting technical pre-qualification on feasibility studies. Getting onto a consultant’s approved-vendor list 12 to 24 months before tender is worth more than any single bid.

State-linked procurement routes through the Central Procurement Board of Namibia and the e-Government Procurement portal, while private operators such as CCC and Omico run their own vendor registration. The Chamber of Mines of Namibia is the fastest way to map who is buying what. The practical entry sequence: register on the operator’s vendor portal, line up a local agent for after-sales service, get onto the EPCM and consultant lists, and price in USD or EUR against a Namibian-bank LC.

The Conventional Channels That No Longer Pay

Most foreign plant suppliers still try to enter Namibia the way they did twenty years ago, and the return gets worse every year.

The Mining Expo and Conference in Windhoek, run by the Chamber of Mines, is the main local set-piece, and the SA-based Electra Mining show in Johannesburg pulls Namibian buyers across the border. Both are useful for relationship maintenance, but the engineers who specify a leach plant for Tschudi or Omitiomire attend in small numbers and are mobbed when they do. Once travel, a serviced stand, and senior engineer time are counted, the cost per qualified RFQ is hard to defend. Regional buyers also attend Mining Indaba in Cape Town, strong for executive relationship-building and weak for transactional lead generation.

The South African distributor lock-in is the structural issue. Because Namibia sits inside SACU and South Africa supplies about 44% of its imports, much of the process equipment and reagents routes through South African distributors and their Namibian branches. That layer adds margin, filters end-customer visibility, and weakens the OEM’s negotiating position each year. For a specialist SX-EW or thickener vendor, the distributor channel rarely carries the technical depth to sell your differentiation, so direct operator and EPC relationships are worth building.

Expat field reps in Windhoek carry a fully-loaded annual cost in the USD 180,000 to USD 250,000 range, and when the rep leaves, the relationships leave too. Print trade press like Mining Weekly Africa still reaches procurement professionals, but paid placement converts poorly. Cold outreach done in English by a sector-literate seller still works in Namibia. The problem is that no single OEM can staff a senior outbound bench across every African copper market at the quality a buyer expects. That is the gap a well-run outbound engine fills, at roughly USD 150 to USD 300 per qualified lead, against USD 300 to USD 900-plus for trade-fair leads and USD 500 to USD 1,200-plus for a field rep, with a cost curve that drops as the engine learns rather than scaling linearly with headcount.

FAQ

Who buys SX-EW leaching plant equipment in Namibia?

Consolidated Copper Corporation runs the Tschudi SX-EW cathode plant and is running feasibility work to restart the Otjihase and Matchless copper mines. Omico Mining is developing the greenfield Omitiomire chloride-leach SX-EW project. These three projects, plus their EPC contractors, account for most copper hydromet demand in the country.

How big is Namibia’s only copper cathode plant?

Tschudi is an open-pit heap-leach SX-EW operation with a 17,000 tonne-per-year cathode design capacity, the only plant in Namibia producing LME Grade A copper cathode. It restarted in August 2024 after four years on care and maintenance and had produced over 80 kilotonnes of cathode before the 2020 shutdown.

Can I invoice a Namibian copper buyer in US dollars?

Yes, and most suppliers do. The Namibian dollar is pegged 1:1 to the rand under the Common Monetary Area, and copper producers earn hard currency on cathode and concentrate exports, so dollar or euro invoicing matches their revenue. The buyer’s Namibian bank handles the local-currency side through a confirmed letter of credit.

What does an SX-EW plant cost to build?

There is no published Namibian figure, but as an indicative benchmark Metso booked a EUR 100 million SX-EW technology contract in early 2026 for a 120,000 tonne greenfield cathode line in Peru. Capex splits roughly across the leach pad, the SX circuit, and the electrowinning cellhouse, so a single-block supplier bids a fraction of the package.

Do I need a local partner to win a leach plant RFQ in Namibia?

Not legally for a cross-border equipment sale, but practically yes. Evaluation committees weight after-sales and commissioning support heavily, so a local agent or service partner strengthens your bid. Getting onto the EPCM and consultant approved-vendor lists ahead of tender matters more than the bid itself.
