These 2 one-day courses offer non-miners a sound fundamental knowledge of the mine cycle – from exploration through to mine closure.
DAY 1 on 14 March
Mining and Geology Fundamentals for Non-Miners
Presenter: Mark Drabble – Principal Consultant
This 1-day course has been specifically designed for non-miners working, investing, financing or associated with the mining industry – who need to understand the key fundamentals about the mine cycle. The course takes you from exploration through to mine closure.
You will learn about: the key geology concepts; drilling and sampling; resource estimation and classification; how a mining company takes a project through to a mining reserve; how to interpret company reports on their mineral resources and exploration results; the mining cycle for underground and open pit mines; the basics of capital and operating costs and how they are incorporated into project valuation; pre-feasibility and feasibility studies; mine planning to optimise production; mine closure; and of course the key terminology of the mining industry.
The course attendees will:
- Gain a greater understanding of the entire mine cycle
- Learn about the operational practices of the mining industry
- Understand and interpret the frequently used terminology
- Have a clear understanding of the key fundamentals and concepts of geology and mining
- Appreciate the importance of drilling and sampling
- Learn about resource estimation, classification and the writing of the reports according to the reporting codes
- How to understand and interpret company reports
- Learn about the different mining methods and understand the principles of mine design and planning
- Learn about the basics of capital and operational costs and how they are incorporated into project valuation
- Gain an understanding of pre-feasibility and feasibility studies
- Learn about mine closure and rehabilitation
“Very educative course, would highly recommend to others.”
“It was all explained very well. Presenter made it all clear and understandable, especially for people not heavily involved in direct mining. Gives a broader understanding of all aspects of mining.”
“I thought it was a great introduction to mining course which gave a good overview of all the topics.”
“A comprehensive course, well presented. Good content. Thanks!”
DAY 2 on 15 March
Understanding Mineral Processing for Non-Metallurgists
Presenter: Dr Leon Lorenzen – Executive Consultant
This 1-day course has been especially designed for engineers, geologists, mineralogists, environmental scientists, plant operators, marketers, financial advisors and anyone who either deals with mineral processing (extractive metallurgy) or would like a better understanding of the principles of extractive metallurgy.
The course looks 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.
