Terrafame zinc mine

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 around 2018. A production rate of around 25kt Ni per annum. While this was half the originally proposed mining rate, the company had hoped to achieve this in 2018. 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 with deliveries to customers commencing in Q3. The battery plant was approved for development in 2018 at a cost of €240 million.
