During his tour of the plant, the Prime Minister was given a lecture on the history of the Norilsk Nickel group, which turns 75 this year.
Mr Putin examined the plant's main rolling mill at the smelter floor where cranes and convectors operate. This mill produces black copper which is further enriched in an anode furnace. The prime minister saw the hot metal poured from the convector into the ladle and loaded into the anode furnace.
The copper plant currently employs about 650 people, mostly Norilsk residents. Some are from other regions.
