Understanding Mineral Processing – for non-metallurgists

This course is also available as live, interactive Online training. Contact Diana Ross – Training Manager

This 1-day course has been designed for engineers, geologists, mineralogists, environmental scientists, plant operators, marketers, financial advisors and those either dealing with mineral processing (extractive metallurgy) or wanting a better understanding of the principles of extractive metallurgy.

The focus of the course is to look at the science of mineral processing from a non-metallurgist’s point of view. It explores principles of geology, mineralogy, chemistry, mineral processing and economics as they apply to mineral processing unit operations and explains in simple terms, from how metal is geologically detected, extracted from various rocks and minerals to the final metal product.

The course provides an overview of extractive metallurgical principles in the design and operation of process plants but also discusses issues such as metallurgical testwork, metallurgical accounting, environmental management and other common aspects of practical extractive metallurgy.
