K+S Minerals and Agriculture GmbH
Zielitz, Germany
March 1, 2019 – December 31, 2022
The plant of K+S Minerals and Agriculture GmbH in Zielitz plans to continue to exploit the existing potash deposit. To continue mining operations in Zielitz until the deposit is exhausted, it will continue to be necessary to dispose of the solid and liquid mining residue. This requires extending the slag heap capacity (HKE II), including all associated infrastructure facilities, and obtaining permission from the water authorities.
The project comprises excavating 340 million tons of residue for a period of approx. 34 years and depositing it on an area of around 200 hectares with a sealed base up to a heap height of 230 meters above mean sea level (approx. 150 meters above ground level) with a surrounding berm in its final condition, including a surface covering, as an extension of slag heap complex 2/HKE. The project also includes the creation of the associated infrastructure on an area of approx. 10.8 hectares, consisting of access roads, pumping stations, an enclosing road, and a fence installation. In addition, it includes the production of a wastewater storage basin with a ground area of approx. 18.9 hectares and a capacity of around 480,000 m³, and the construction of an effluent pipeline with a length of approx. 5.5 km.
