Comparison Test Weir Minerals

Introduction

Weir Minerals was tasked with conducting pipe loop test work for the Sokli project in Finland. This project aims to establish a regional European source of Rare Earth Elements (REE) metals, crucial for various applications including the production of wind turbines. As part of this initiative, Rhosonics was invited to test the SDM ECO sensor in the test loop, alongside a Coriolis meter and a nuclear density gauge, to evaluate their performance for density measurement.

Our solution

Weir Minerals invited three suppliers of density and flow meters to validate their density-measuring methods. These suppliers employed different technologies to determine slurry density:

1. Radiation (Nuclear)
2. Acoustic impedance (Ultrasonic)
3. Flow meter (Coriolis)

These technologies were compared over two weeks, during which data from each measuring instrument was collected and analyzed.

Results

The purpose of this visit was to test the MPC (multipoint calibration) and accuracy of the SDM ECO at Weir Minerals’ test loop center in Venlo. This opportunity allowed us to gain extensive insights into the capabilities of the SDM ECO.
