Remarks | The utilization of sulphur containing gases after zinc concentrate roasting is carried out at the sulphuric acid plant resulting in marketable sulphuric acid. The sulphuric acid plant has four sulphur containing gas treatment systems of total capacity 103 thousand Nm3/hour. At present the reconstruction of system No.5 of 40 thousand Nm3/hour design capacity is under way. SO2 concentration in the roasting off-gas is in the range of 8 – 9.5%. The process of oxidizing SO2 to SO3 is conducted in the double contacting scheme. The achieved contacting level is 99.8%. The use of "Begg Cousland", "KKK", "Alfa-Laval", "Haldor Topsoe" companies equipment allows to achieve SO2 content at the outlet to the atmosphere not more than 0.05%. Presently 1.5 t of sulphuric acid per 1 t of cathode zinc is produced. | |

April 28, 2009 - Russia's Chelyabinsk Zinc Plant said it produced
36.7 percent less zinc and zinc-based alloy in Q1 2009 than in the same
period last year. Production cuts part of company's cost-cutting measures.
October 2, 2008 - Chelyabinsk Zinc Plant has completed
implementation of a big investment project, having put the sulphuric acid
system (Unit No.4) into operation upon its complete overhaul. The value of
the project amounts to $35 mln. |
