Outotec has agreed with Glencore Nikkelverk AS on the delivery of coated titanium anodes to the new tankhouse for its copper electrowinning plant in Norway.

The delivery will include over 5,000 of the new mixed metal oxide coated titanium anodes, with the order value, booked into Outotec’s September quarter order intake, being some €10 million ($11 million).

Glencore’s Nikkleverk refinery in Kristiansand, Norway, produces around 40,000 t/y of copper.

Outotec’s coated titanium anodes were tested on-site for five years, with the results verifying that Outotec anodes will significantly reduce energy consumption and provide higher current efficiency than traditional lead anodes, the company said.

Outotec said: “Outotec Coated Titanium Anodes provide totally lead-free electrowinning operations and increased occupational health and safety by eliminating lead and lead sludge handling.”

The end result for Glencore Nikkelverk AS is green technology electrowinning operations with higher quality copper product at lower energy consumption and operating costs, it concluded.

Kalle Härkki, Head of Outotec’s Metals, Energy & Water business area, said: “This is one more reference delivery of Outotec Coated Titanium Anodes in the copper electrowinning industry. The energy efficiency benefits and lower operating costs of our anodes enable Glencore Nikkelverk to improve their profitability in a sustainable way.”
