Kemi Mine

The Kemi Mine is owned by Outokumpu Chrome Oy, a subsidiary of Outokumpu Oyj. It is located in Elijärvi, in the municipality of Keminmaa, to the north of Kemi. The Kemi Mine is the largest underground mine in Finland, with an annual production capacity of 2.7 million tonnes of ore. It is also part of the integrated ferrochrome and stainless steel manufacturing chain owned by Outokumpu in the Kemi-Tornio region. The Kemi Mine has approximately 400 employees every day, both employees of Outokumpu and contractors.

The purpose of the Kemi Mine in the long production chain from chromite ore to stainless steel is to produce concentrates from ore as raw material for the manufacture of ferrochrome at the ferrochrome plant located in Tornio. The chrome contained in the ferrochrome generated as a product at the ferrochrome plant – used as an alloying material in the steel manufacturing process – is what makes the steel manufactured at the Tornio steel plant stainless.
Operational safety, cost-effectiveness and eco-friendliness are characteristics of the Kemi Mine. Low accident figures, together with clean and properly organized working environments, both 500 meters underground and on the surface, make an excellent setting for effective production, modern technological applications and the use of advanced working methods. Operations cause only a minor environmental impact because of the insolubility of the oxidic chromite ore, the chemical-free concentration method based on gravity, and the sealed process water circulation covering the entire mine and concentration process.

Kemi Mine is offering research and testing co-operation in mining and concentrating environment.

Facilities and infrastructure consist of
• Challenging environment with moisture, vibration, dust and tunnels
• Underground facilities down to 1 km depth
• Modern WLAN network, mining machines, centralized data base, gravity separation process, sealed process water circulation
• All phases of mining process (mining, crushing, grinding, separation, concentration, water treatment)
