How to Use Real-Time Data to Guide Raw Material Blending in Alumina Production

In alumina (Bayer process) production, the goal of “raw material blending” is not to achieve the highest grade but rather to consistently operate the digestion, settling, and calcination systems within their optimal performance windows at the lowest possible overall cost.

In the alumina industry, flow measurement challenges caused by scaling.

In the Bayer process for alumina production, scaling—also known as fouling or deposition—is a highly typical issue that interferes with flow measurement. Deviations in flow measurement directly lead to inaccurate control of the production process, making it impossible to achieve true automation in production.
