The presentation by Prof. Dr. H.Z. Harraz outlines the mining cycle, focusing on the selection of mining and processing methods to maximize profit while considering safety, environmental factors, and market conditions. It highlights the differences between surface and underground mining and emphasizes the advanced safety standards and engineering involved in modern mining practices. The document also notes that the mining industry is currently a significant employment center for geologists.

3. Mining Geology
• This is one of three employment centers for
geologists, and it is presently enjoying a
boom. The other boom employers are:
• The Petroleum Industry
• The Environmental Industry

4. Modern safety standards mean that most modern mines, at least those
constructed by large corporations, are engineering marvels. They are
expensive, and are not constructed unless the commodity sought is known
to be present in profitable quantities and is recoverable.

5. Choice of mining and processing methods:
“The simple aim in selecting and implementing a
particular mine plan is always to mine a mineral
deposit so that profit is maximized given the unique
characteristics of the deposit and its location, current
market prices for the mined mineral, and the limits
imposed by safety, economy, environment”
