What LuNa Smelter Ltd does

LuNa Smelter Ltd is a privately held tin smelting and mining company headquartered in Kigali, Rwanda, founded in 2018 as a joint venture between Polish metallurgical group Luma Holding and Rwandan investment group Ngali Holdings. The company acquired and modernized a dormant tin smelter originally built in 1980, commissioning two Electric Arc Furnaces (EAF) with a combined 1000 KVA capacity to process 200-230 tons of cassiterite concentrate per month. Output includes refined tin ingots in three purity grades (LME Standard Sn 99.86%, High Quality Sn 99.96%, and Premium Sn 99.99% produced via spiral crystallizer refining), as well as by-products (tin drosses, low-tin tantalum slag, tantalum concentrate). The company owns and operates the Mbogo Mine in Rwanda's Eastern Province with its own mineral processing plant and underground hoisting system, providing upstream vertical integration into cassiterite feed.

LuNa generates revenue through three primary streams: (1) tin ingot sales at LME-linked commodity prices to enterprise buyers in electronics, solder, battery, and renewable energy industries; (2) contract tolling services for external cassiterite suppliers requiring RMAP-conformant processing; and (3) ISO/IEC 17025-accredited laboratory testing services for regional mining and exploration clients. Pricing is commodity-driven with no public disclosure; contracts are negotiated directly with enterprise customers supported by industry certifications critical for accessing international markets. Go-to-market is enterprise field sales, augmented by participation in industry conferences (Mining Indaba, EPRM, RMI, LME, OECD, Paris Peace Forum, Future Minerals Forum, TIC, Rwanda Mining Week) and ESG reporting under GRI standards.

LuNa's principal differentiators are regulatory and traceability-related: it was the first tin smelter in Africa to achieve RMAP certification in 2020, a status formally recognized by the European Commission in 2025 as a supply-chain due diligence scheme under the EU Conflict Minerals Regulation. The company maintains four ISO certifications (9001:2015, 14001:2015, 17025:2017, 45001:2018) and operates a proprietary Chain of Custody system formally licensed by the Rwanda Mines, Petroleum and Gas Board (License No. RMB/ESP/01/042022/042027), augmented by blockchain documentation through a Minespider partnership piloted with Google. By positioning processing within Africa rather than shipping concentrate overseas, LuNa claims a lower CO2 footprint and zero-waste production practices (achieved in 2024), targeting European and American buyers with conflict-free, traceable, sustainably produced tin.

Core offering

LuNa Smelter Ltd is a vertically integrated tin producer that mines and refines cassiterite concentrate into high-purity refined tin ingots (Sn 99.86% LME Standard, Sn 99.96% high quality, and Sn 99.99% premium grade) using Electric Arc Furnace and spiral crystallizer technology. The company also offers tolling/smelting services for external cassiterite owners, by-products (tin drosses, low-tin tantalum slag, tantalum concentrate), and ISO/IEC 17025-accredited laboratory testing services for the regional mining sector.

Product overview

LuNa Smelter Ltd operates as a vertically integrated tin production company with a diversified portfolio of products and services. The core offering is refined tin ingots available in three purity grades (LME Standard 99.86%, High Quality 99.96%, and Premium 99.99%), complemented by by-products including tin drosses, low tin tantalum slag, and tantalum concentrate obtained during the smelting process. The company operates its own Mbogo Mine for captive cassiterite supply and provides tolling services for external customers. A key differentiator is the proprietary Chain of Custody (CoC) traceability system licensed by Rwanda's mining authority, combined with ISO/IEC 17025 accredited laboratory analysis services offered to external clients.
