Hannukainen Mining Oy is owned by Tapojärvi Oy, a Finnish family-owned business based in Kolari. The Kolari - based family company bought all the rights and exploration materials related to the project from the bankrupt estate of Northland Mines Oy. The iron, copper, and gold deposits of the Hannukainen area will now be utilised domestically.
Tapojärvi enjoys a long history of diverse mining projects, material handling as well as managing factory and industrial processes in different parts of Finland and Sweden.
Tapojärvi takes the environment into account in its operations, and keeps seeking new solutions that support the principles of sustainable development and affect the environment as little as possible. The company engages in continuous development and research of utilisation of industrial side streams and reusable materials.
Each year, Tapojärvi brings around 700,000 tons of industrial by-products into commercial production in Finland alone. This corresponds to, for example, slightly less than one third of the municipal waste of all of Finland.
Tapojärvi has two unique valorisation plants in Tornio, where by-products of ferrochrome and refined steel slag are made into their own CE-marked products. Construction of a third concentration plant is being planned.
In Finland, Tapojärvi employs more than 400 employees, and around 150 people are employed by subcontractors.
Tapojärvi is certified according to the requirements of the ISO 9001 standard.
