About Us


Luna Smelter is a leading tin producer located in East Africa, in Kigali – the capital city of Rwanda. This project is being developed by Luma Holding Ltd jointly with its Rwandese well recognised partner Ngali Holdings Ltd.

The main focus of the LuNa Smelter is to create a value of the company by creation of a modern, sustainable industrial plant – unique for the Central and East Africa region.  LuNa Smelter is designed and planned to become a leading African conflict free, high quality tin supplier, as well as a producer of other minerals obtained during the production process, such as tantalum concentrate from the post production slag. With starting capacity of ca. 300 tons of tin metal per month, LuNa Smelter will conduct activities leading towards launching a second fully automatised production line, what will raise the production up to 600 tons per month.

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

LuNa Smelter activities have already boosted the entire industrial and mining sector of East Africa, especially 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 Trading is a 100% subsiduary of Luna Smelter Ltd, registered in Zug Switzerland.

Our history

The Kigali based Karuruma tin smelter was built in the early 1980’s to produce tin from concentrate coming from the “Société des Mines du Rwanda” (“SOMIRWA”). SOMIRWA managed the smelter until 1985 when it went bankrupt.

The smelter was reopened at the end of 1990 by a company called ALICOM but was closed again in April 1994 when the genocide started. After the Liberation War, smelter was privatized by the Rwanda government and until 2018 was belonging to several investors.

Luma Holding Ltd and Ngali Holdings Ltd have taken over the Smelter in the first half of 2018, after successfully winning of the  purchasing tender organized by the I&M Bank. Companies have registered a JV company in Kigali, Rwanda – Luna Smelter Ltd, which is decided for the development of the plant and its operations.
