Terrafame nickel operation
In August 2015, Terrafame, a state-owned Finnish company, purchased the assets of Talvivaara's operating subsidiary, Talvivaara Sotkamo, and assumed responsibility for the mine and processing plant. The company restarted mining at Talvivaara in September and the ramp-up of the mining operations proceeded on schedule. The Government granted Terrafame two years to rescue the operations of the bankrupt Talvivaara Sotkomo. Terrafame was aiming to mine around 18Mt of ore per annum by 2018 at a production rate of around 25kt Ni per annum.Since this time paid nickel production has increased to 30 kt/a Ni and 55 kt /a Zn. In June 2021 Terrafame reported that production had started to ramp-up at its new battery chemicals plant which was approved for development in 2018 at a cost of €240 million.
