Copper smelter / Vanyukov furnace
As part of a major project to modernize the copper smelting plant in Almalyk, Uzbekistan, the construction of a new Vanyukov furnace was initiated in 2014. This furnace, which enables an annual production of 73,800 tons of blister copper, represents a significant advance in efficient copper production. With the new smelting technology in the slag bath, we were able to improve both production efficiency and the environmental footprint by processing sulphurous waste gases in a sulphuric acid plant.
Commissioning: September 2018
