MMK Upgrades Mining Facilities

UrBC, Magnitogorsk, September 8, 2017. Magnitogorsk Iron & Steel Works (MMK) ore mining and processing facility turns 86 this year, MMK Information & PR Department reports.
The facility comprises Rudnik, an ore processing plant, a sintering plant, a crushing and calculating shop, and a sintering mix treatment shop.
‘We keep upgrading our existing equipment and launching new units. For one, we had our Sulphur-Trapping Unit 4 reconstructed: as a result, our exhaust gases are 90% sulphur-dioxide free, which means our atmospheric emissions were reduced considerably. The decrease is estimated at 250,000 kg a year,’ the Department says.
Sulphur-Trapping Unit 2 was also re-launched after a reconstruction. A new gas-filtering unit was launched in September 2015, another one in June 2016, and yet another one in September 2016. This means we actually have a totally new filtering facility in place of the old one that was launched as early as 1963.
‘We are now operating three gas-filtering units that all consist of two filtering stages (an electric filter and a scrubber); their function is to trap solid particles such as dust and to trap sulphur dioxide. The overall capacity of our new Sulphur-Trapping Unit 2 allows for filtering of the entire amount of gases produced by Sintering Plant 2. The average dust-trapping efficiency comes to over 99%, with the resulting product 95% sulphur dioxide-free. This has meant our emissions dropped by 917,000 kg a year for dust and by 7,618,000 kg a year for SO2.’
