First Underground TOMRA Sensor-Based Sorter Deployed At Rock Salt Mine

Salt producer K+S Minerals and Agriculture turned to TOMRA Sorting Mining to replace the existing sorting system at its rock salt mine in Grasleben, Germany.  

At the Grasleben mine, rock salt is extracted from a high-quality underground deposit and is then processed into a wide range of products, which includes food-grade table salts. For K+S, consistently achieving certified and guaranteed high purity, compliant with the strict standards of the food industry, is a priority.

“The sorting of rock salt is complex and demanding due to its crystalline properties. This leads to strong fluctuations in the appearance of the material,, Sven Raabe of K+S Minerals and Agriculture, said in a release.
