The Talvivaara mine is one of the largest nickel mines in Finland.[4] The mine is located in Sotkamo in Kainuu region of Finland. The mine is owned by government-established Terrafame, which bought it from the bankruptcy-bound Talvivaara Mining Company in 2015.[3] Its annual production capacity is over 10 million tonnes of ore. The mine has reserves amounting to 1 billion tonnes of ore grading 0.22% nickel, 0.13% copper, 0.5% zinc and 0.02% cobalt thus resulting 2.2 million tonnes of nickel, 1.3 million tonnes of copper, 5 million tonnes of zinc and 0.2 million tonnes of cobalt.[4]
The mine had suffered several leaks of toxic metal-contaminated tailings, which had threatened local waterways. Members of the management were charged with criminal environmental offenses.[5]
