Using solution mining for theextraction of rock salt, potash salt, trona and other raw minerals in has clear advantages over conventional mining: Solution miningtechnology is not only cheaper but also safer. Costly pit construction is not required either, and there is a significantly reduced personnel requirement. The raw materials obtained are used in many different ways: Brine can be processed into table salt or de-icing salt, it can be used in the chemical and pharmaceutical industries or for the production of fertilizers.

Exploratory drilling, resource calculations and cost-effectiveness considerations provide the basis for deciding whether a brine extraction project can be implemented. Technical considerations provide further details. This process enables operators who want to market a high-quality product to plan for the long term.

Salt caverns in solution mining require highly differentiated knowledge. Even if salt dissolves perfectly in the lab, ideal rock composition or mineral concentration cannot be expected in nature. Geological conditions provide the framework, while chemical, physical and thermodynamic factors influence how intensively the deposit can be used and what residues are produced and in what quantities. Carefully planning a suitable solution mining process is critical to the profitability of an operation and to the product quality.

That is why DEEP.KBB also uses a comprehensive, interdisciplinary approach to solution mining: Using 3D computer simulations, geoscientists and engineers work together in the lab to develop an extraction process that is optimally adapted to the respective deposit.
