LECTURE 1 AN INTRODUCTION TO MINERALS, ORE AND EXPLORATION. This first lecture covers basic geology and introduces terms such as minerals, mineralization and ore. It also introduces exploration, how it is done and why. We use metals in most of our everyday items, such as phones, computers, cars, cutlery and infrastructure.
This lecture covers mining and introduces how mining generally is done, what machinery and methods are used and how ore and waste rock travel within the mine complex. Mining is done to liberate minerals from the crust of the earth. This is done in several steps. The steps differ between mines depending on commodity and factors such as composition and quality of the rock, the geometry and
Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts Figs. 1, 5 and 6, more time, and more commitment of scarce capital.
MINING OVERVIEW Introduction The U.S total domestic mining and waste removal for nonfuel mineral materials production amounted to 5.9 billion metric tons Gt in 2007 most current year final statistics are available.These materials included 4.5 Gt of crude ore mined or quarried and 1.4 Gt of
minerals and pyrite from low-grade copper ores and mining waste waste rock, overburden, oxidized portions of the ore body proceed according to the following stoichiometric equations shown in Table 1 16. Dump, heap and in-situ leaching are the most common hydrometallurgical methods for
Mineral dressing Orebeneficiation The first process most ores undergo after they leave the mine is mineral dressing processing, also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...
