Production flowchart of Norilsk Nickel Harjavalta

From 2H 2016, the refining facilities in Monchegorsk have been gradually increasing their nickel feedstock supplies in line with the Group’s nickel production reconfiguration strategy. Feedstock supplies from third parties continued unabated and included converter matte from BHP (Australia), matte and converter matte from Boliden Harjavalta (Finland), converter matte from BCL (Botswana), and nickel sulphide concentrate from Terrafame (Finland).

In 2016, Norilsk Nickel Harjavalta produced 53.7 kt of seleable nickel, up 23% y-o-y, owing to reconfiguration of the Company’s refining facilities and, consequently, larger nickel feedstock supplies from Kola MMC.

The third party sales of copper in copper cake totalled 9.6 kt, down 26% y-o-y. This was mainly due to the increased supplies to Kola MMC.

Nickel and copper recovery rates improved on the back of a decrease in losses of nickel and copper with ferrous cakes.
