It was operating at royal expense as the country's largest copper plant. The plant was finally officially closed down in 1812, but sporadic operation took place until 1912.

Tynset is first mentioned directly in 1211 when the archbishop of Nidaros consecrated the new stave church. At Kvikne and in Tylldalen, many fine memories from Catholic times have been preserved. Five years before the church consecration, the municipality is indirectly described in Håkon Håkonsson's saga as an area that supported the anti - church birch bones, before they came down from the mountain in Ålen at the top of Gauldalen in Trøndelag in 1206. The first farm mentioned in Nord-Østerdal is Sørgård in Tylldalen. It is written in a leather letter "på gildevangen" in Ålen in the summer of 1381. In the land register for Ålen in 1638, Røros farm is said to be located "on the thinned forest", then there were no mines on Røros, only on Kvikne.
