Alumina Processing Fundamentals

WAAPF34
(Engineering)

Outstanding Features

Engagement in this course will enable plant process personnel to make better and timelier process decisions, leading to reduced production loss opportunities and reduced material consumption.

Our global expert will provide a processing overview for technical and production personnel involved in running and optimizing the processing functions in an alumina refinery.

Course Overview

The course aims to provide participants with an understanding of materials used in the Bayer process, Bayer process chemistry, typical Bayer process unit operations and their impacts, appreciation of key product quality parameters and their impact on downstream smelting operations.

Target Audience

The course is aimed at refinery personnel who are unfamiliar with the fundamentals of the Bayer Process.It is recommended for junior process engineers and supervisors, with little or no alumina refinery experience.
