The quartzite mine at Elkem Tana has been operated by Elkem since 1983. The deposit has proven resources for more than 50 years production and it is one of the world largest quartzite mining operations.
The quarry has an annual production of approx. 850 000 mt, which is shipped to Elkem customers as well as other industrustrial customers in northern Europe.
The quartzite deposit is located close to the Barents sea and the loading system makes shipments of up to 7 500 mt possible. Despite being localized in the Arctic region, the harbour is ice-free and mining and shipping operations proceed throughout the year.
Depending on chemical quality of the quartzite, the applications are for silicon-, aluminum- and ferrosilicon alloys and iron oxide pellets.
Elkem has operated the Mårnes quartzite mine since 1970. The mine is the second largest quartzite mine in Norway. The deposit has proven resources for more than 40 years production.
The quartzite is mined by open pit mining and operated by a sub-contractor. The rock material is transported by dumpers from the pit to the processing plant. The processing plant is close to the harbour and outdoor storage area.
Annual production is approx. 150 000 mt and the applications of the quartzite are in ferrosilicon- and silicon manganese alloys and iron oxide pellets and cement additive.
The quartzite is located close to the sea and vessels up to 3000 mt could be loaded.
