Talvivaara resumes ore production

The Talvivaara Mining Company resumed ore production at the company's Sotkamo mine on Monday after heavy rains and leaks of process waste water forced it to halt operations in September.

After a close to nine month hiatus, the mining of ore was restarted on Monday. Processing is to be gradually ramped up. It was originally expected to restart mining operations in the summer.

According to the company, the resumption of ore production will improve overall water levels and site water management. Heaps of freshly mined ore bind water equivalent to 10-15 percent of their mass. For example, 10 million tons of fresh ore binds at least one million cubic metres of water.

In 2011, the Talvivaara mine at Sotkamo produced 11.1 million tons of ore. Last year, 8.7 million tons were produced before mining operations where shut down in September.

The poignant scenes of the return to Holland of the bodies of the victims of flight MH-17 dominate Finland's press this morning. Alongside the reports on the latest diplomatic moves to try and secure Russian co-operation over the Ukraine crisis, some papers take a moment to revisit Finland's recent run-ins with its eastern neighbour, and explore the worst-case scenario should Russia's economy crash. Elsewhere, papers reveal a widespread lack of background checks on those working with children, and an overview of Finland's economic outlook makes bleak reading.
