At public hearings, ArcelorMittal Kriviy Rih presented the report on assessment of environmental impact for the project on reconstruction of secondary and fine crushing building at production area No. 2 of Crushing Plant (CP).
Area No. 2 of Crushing Plant is used for receiving and processing of ore extracted from open pit No. 2-bis (area No. 1 is used for ore extracted from open pit No. 3). Area No. 2 includes secondary and fine crushing building, which comprises five process lines – two secondary crushing lines (from 0–350 mm to 0–75 mm) and three fine crushing lines (from 0–75 to 0-16 mm). Each line includes feed conveyor, cone crusher and scalping screen.
The design implies installation of two more new lines, which will enable to balance production on both sides of the building with conveyors. It will enable to create a back-up of facilities, perform planned and capital repairs of all lines, exclude yield losses in case of unplanned idles. In addition, product quality will improve due to reduced amount of crushed ore output, the factions of which exceed the required technological norms.
There will be seven process lines after reconstruction is completed, and two of them will be back-up, which will help to stabilize production and operational capability of secondary and fine crushing building. Total productivity will not exceed design level and will reach 15.5 million tons a year. The cost of this project on reconstruction of production area No. 2 of Crushing Plant is estimated at $8 million.
Project presentation prepared for public hearings shows the main air pollutant sources during construction and mantling works, as well as environment protection measures to minimize emissions. The presentation includes layouts that reflect the distance from the building to the nearest residential area – 1420 m (with the norm of 300 m), detailed analysis of ground level concentration calculation in control points, characteristics of waste that will be generated during reconstruction and other data.
This project’s impact on water, air, geological environment, condition of flora and fauna, biodiversity, land and soil is within the tolerance. There is no impact regarding all other factors covered by legislation. (AMKR/Ukrainian metal)
