Lesson 1 Flashcards
Extracted from ground through different mining methods
Ore or Run of Mine Ore
Naturally occuring mineral with economic value
Ore
Defined as the art and science of extracting and refining metals from primary and secondary sources to characterize, process, and fabricate for application and use at a profit with utmost consideration of the environment
Metallurgy
Science of extracting these metals from the valuable minerals in an ore and convert it to metal form or final product
Metallurgy
HISTORICAL EVIDENCES ON THE EXISTENCE OF METALLURGY
artifacts of jars, plates, arrowheads, axes, and other farm implements, as well as the walls of prehistoric caves where crude drawings showing the existence of such artifacts were found

Iron, smelted
Mercury
Growth of Metallurgy
-the ores must be found, separated and sized before use
-the ores must be reacted under a controlled temperature and gas atmosphere
-the liquid metal must be collected and cast into a desired shape
-metals must be worked to achieve desired final properties shape
In order to obtain the metal products, ores must be:
- Found, mined, and sorted
- Crushed and separated to obtain the valuable minerals
3.reacted under a controlled temperature and gas atmosphere to obtain the liquid metal for casting and worked to achieve desired final properties and shaped.
DIVISION OF METALLURGY
branch which deals with the gathering of valuable minerals from run of mine ore
MINERAL PROCESSING
DIVISION OF METALLURGY
branch which focuses on the extraction of metals from the valuable minerals obtained during mineral processing
EXTRACTIVE METALLURGY
DIVISION OF METALLURGY
branch which deals with problem solving i.e. development of metallic alloys needed for different types of manufacturing and construction
