The mining and processing complex of Magnitogorsk Iron and Steel Works comprises of a mine shop, an ore-dressing factory, a sinter shop, a grinding-kilning shop and the sinter charge preparation shop.
For the past several years the shop has undergone a massive reconstruction. In particular, the company has reconstructed the sulfur-exhaust machine, which allowed increasing gas purification to 90% and considerably decreasing air pollution. The project resulted in the sulfur dioxide pollution decrease by 250 tons per year.
In 2017 MMK started constructing the new sinter factory with the capacity of 5.5 million tons. The cost of the project is 22.6 billion rubles. (Ukrainian metal)
