Thickener Underflow

Introduction

A major chrome beneficiation and PGM processing site on the Eastern Limb of the Bushveld Igneous Complex in South Africa depends on precise thickener underflow density control for stable production. With nucleonic meters creating increasing operational and compliance burdens, the site began evaluating non-nuclear solutions that could deliver equivalent performance.

Our solution

The objective was to continuously measure the density of thickener underflow slurry with high reliability and fast response to process changes. The measurement needed to match the performance of the current nucleonic system while avoiding the safety risks, compliance requirements, and licensing delays associated with radioactive technology.

Results

The trended comparison data confirmed that the Rhosonics SDM tracks the process with the same accuracy as the installed nucleonic meter. In addition,
the SDM responded noticeably faster to density fluctuations, giving operators more immediate visibility and enabling quicker process correction.

Following the trial, the client expressed strong satisfaction with the SDM’s performance. Beyond measurement quality, they highlighted the unit’s ease
of use and the practical advantage of eliminating radiation-related administration, safety procedures, and recurring compliance costs.
