Potassium content measurement for the potash industry is one of the most difficult and challenging measurements in the mining industry. However, it is essential in the potash production process. Potassium contains the radioactive isotope K-40. This isotope is only found in extremely small quantities in the ore itself. The detection of the K-40 requires an extremely sensitive and superior stable measurement system that must be able to suppress the inherent background radiation in order to obtain an optimal signal-to-noise ratio. Through the detection of K-40, the concentration of K2O or KCl can be measured.

Berthold offers a solution for the challenging task, providing accurate potassium measurements with the LB 474 potassium analyzer. The system is non-contacting, which virtually eliminates maintenance and costly downtime. Applying highly sensitive, stable, and rugged detectors is fundamental for achieving a precise measurement. The LB 474 potassium analyzer uses three different types of detectors depending on the process conditions and the mechanical arrangement.
