ArcelorMittal Kryvyi Rih announced on 20 December 2021 that there was a leakage of process water from the eastern slope of TSF Tsentralne amounting to about 80 thousand cubic meters that represents 4% out of the overall capacity of the facility basin. The TSF basin was not overfilled. Accumulating pond, which is at the foot of the facility, prevented further run-out of the water. Nearby the TSF, there was a security service premise, belonging to AlfaPremiumGroup company, with a guard inside it. Kryvyi Rih State Emergency Response team promptly evacuated the guard to a safe place, there's no risk to his life. ArcelorMittal Kryvyi Rih is eliminating the consequences of the incident. There is no hazard for people, environment and the surrounding areas. Currently, ArcelorMittal Kryvyi Rih is actively operating two TSFs Myrolyubivske and Obiedinennoie. However, these facilities have almost reached their ultimate life in dams' raising. This resulted in the need to reconstruct TSF 'Tsentralne' and to construct a new facility for waste storage - TSF Karta 3. The company will commission the TSF into operation in parallel with the completion of the current tailing ponds life. Operation of the new TSF will allow to reduce the overall impact caused by the slurry facilities on the atmosphere. TSF Tsentralne is a new asset of the company's Mining Department, having the smallest footprint area. Total storage capacity of the tailing damp makes around 2 million m3. The company started construction in 2017, so far, the dams have been raised up to elevation +105 m. The whole basin of the TSF has been lined with water-proof mats made of non-toxic material that is bentonite, which completely excludes penetration of process water into underground aquifers, thereby excluding technogenic load on the surrounding areas. TSF Tsentralne rests in the gully between steel-making slag dump and TSF Myrolyubivske, at a distance of 3-5 km to the nearest residential zone. Tailing Ponds are the hydraulic facilities which are used for storage of water and waste generated by processing & beneficiation of mine rock. There are at least 3,500 tailing ponds worldwide. The slurry is transported to the TSF via pipelines, solids get deposited on the bottom and the water is recycled in the process of hydraulic separation.
