LuNa Smelter - a leading, conflict-free, high-quality tin producer

LuNa Smelter is a leading tin producer located in East Africa, Kigali – the capital city of Rwanda.

LuNa Smelter is a leading, conflict-free, high-quality African tin supplier, as well as a producer of other minerals obtained during the production process, such as tantalum concentrate from the post-processing slag. LuNa Smelter activities have already boosted the entire industrial and mining sector of East Africa, especially the development of the new 3T mining projects. The company is open for cooperation with cassiterite tin suppliers from the region, who respect environmentally friendly and socially responsible conflict-free business practices.

LuNa Smelter products will be introduced to the European market by its trading company, LuNa Trading, based in Zug, Switzerland.

Conformant Smelter Status granted by the Responsible Minerals Initiative. Beginning of the cooperation with Better Sourcing Program and the implementation of the BSP supervision at Bugarura and Kuluti mining sites.

3Q 2019

Bugarura & Kuluti exploration licences obtained by LuNa Smelter. Commencement of the exploration activities. ISO certificates granted: ISO 9001:2015 and ISO 14001:2015.

1Q 2019

Beginning of the project: “Rwandan multi-scale geological ranking – identification of cassiterite exploration assets for further development”.

4Q 2018

Investment into LuNa Laboratory. Further investment into Smelter infrastructure.
EIA approval awarded by REMA Rwanda Environment Management Authority.

3Q 2018

Granting of the EIA approval and all of operational licences as well as the permissions for the trading of 3T minerals. Complete traceability certification – a full ITSCI member.

2Q 2018

Modernisation, refurbishment and launching of the Smelter production – high-grade tin ingots (average grade 99.96% Sn).

2018

After having won the tender organised by the I&M Bank, Luma Holding and Ngali Holdings took over the Smelter in the first half of the year. The companies have registered a JV company in Kigali, Rwanda – Luna Smelter Ltd – established with the purpose of the development of the plant and its operations.

1990

Reopening of the smelter by a company called ALICOM. However, it was closed again in April 1994, when the genocide began. After the Liberation War, the smelter was privatised by the Rwanda government and, until 2018, it changed hands several times.

1980

The Karuruma tin smelter was built in Kigali to produce tin from concentrate coming from the “Société des Mines du Rwanda” (“SOMIRWA”). SOMIRWA managed the smelter until 1985, when it went bankrupt.

Production plant

Tin smelter

LuNa Smelter is equipped with 2 EAF with a total capacity of 1000 KVA. Each furnace has three graphite electrodes of 350 mm. For the impurities control the plant has three refining furnaces. Another two segregation furnaces are used for the recycling of the scrap from the refining and collect the tin from it. One furnace is used for ingots process. Pure tin metal is being transferred from the refining furnaces to the ingots furnace and then – distributed to molds. The plant has special devices for magnetic separation for enriching of cassiterite (tin ore).
