Process design is the starting point of every project for processing plants, no matter whether it is a new plant, a capacity increase or a modernisation project. The result of the process design is the guideline for the complete project development, thus special care has to be taken.


has more than half a century of experience in process design throughout the mineral salt industry. More than 500 projects treating more than 40 products have been handled by our engineers.

Continuous Monitoring of new developments and cooperation with reputable universities and equipment suppliers enable us to always offer our services based on most modern know-how. Our highly motivated team, further educating themselves on a regular basis, is our most valuable resource and the key to quality and customer satisfaction.

Our services comprise, among others

  • Process Design

  • Process Optimization

  • Mass and Heat Balances

  • Dimensioning of Equipment

  • Laboratory and Pilot Plant Tests

  • Supervision of Start Up

Using modern software tools and our know-how regarding dissolution equilibriums incorporated in complex calculation tools we design processes for the processing of ore, bittern and brine from solution mining and natural lakes using the process steps

  • mechanical treatment (dry and wet milling, screen settling, stream settling, flotation, mechanical debrining, compaction)

  • thermal treatment (hot and cold leaching, evaporation and crystallization, drying)

  • chemical treatment (decomposition reactions, precipitation reactions, bromine and iodine extraction, gas – liquid reactions for carbonisation, exchange of salts)
