Metallurgical Engineers separate valuable minerals from waste rock, extract metals for the minerals, treat the metal to achieve accessible properties, manufacture the metal into a useful final product. The University of Utah How important is extractive metallurgy? If China 1. Everything we use whether ancient or modern comes from the earth.
If it wasnt grown, it was mined. If it was mined it was processed into a useful product whether coal for a furnace or microelectronics for a computer.
Both properties make it a useful material for the construction of machinery by casting. It is readily machinable due to graphite flakes and is an economic material since it has a low melting point of about DC.
It has, however, poor toughness and limited tensile strength. White Cast Iron. Produced by melting pig iron and steel scrap. After solidifIcation no carbon is precipitated but remains in combination as iron carbide.
It is hard, brittle, and unmachinable. It is used for making grinding balls, dies, car wheels, but mostly used for making malleable cast iron. Malleable Cast Iron. Prepared from white cast iron by annealing for several days, whereby iron carbide is decomposed into iron and graphite in form of nodules.
It is more ductile and more resistant to shock than grey cast iron. It is used in large quantities for such materials as pipes and pipe fittings and the automative industry requiring higher mechanical properties. Ductile Cast Iron.
It is a high-carbon ferrous product containing graphite in the form of spheroids. The spheroid is a single polycrysalline particle, whereas the nodule is composed of an aggregate of fine flakes.
Ductile cast iron has all the advantages of cast iron, e. It is used by the automotive, agricultural instruments and railroad industries, pumps, compressors, valves, and textile machinery. This addition catalyzes the decomposition of carbon into spheroids and not flakes. High-purity iron possesses temporary magnetism, i. For example: Abundance of elements in the Earths Crust Where in the earths crust can these resources be obtained?
We recover these resources from locations in the earths crust where they are concentrated in ore bodies. Enrichment Factor is used to describe bodies of mineral ore.
It is defined as the minimum factor by which the weight percent of mineral in an orebody is greater than the average occurrence of that mineral in the Earth's crust. Abundance of elements in the Earths Crust Enrichment Factors that relate to the economic viability of an orebody are largely determined by the following: The value of the mineral the higher the value of the recovered mineral the more expensive the recovery process can be in order to obtain it this could include processing larger amounts of ore.
The cost of refining the mineral once recovered this may require the bulk of the price demanded by the final product, so leaving little margin for the initial recovery of the mineral. Other macro-economic factors such as fuel prices if the mineral requires a large amount of transportation or energy prices if the recovery and refinement process is inherently energy intensive.
What causes ore bodies to form? Geological events such as earthquakes, volcanic eruptions, erosion, natural leaching are often necessary to form mineral deposits.
These events concentrate mineral in locations that are accessible to mining. Such events are often associated with the formation of mountains, and it is not just a coincidence that most mine sites are located in mountains. How do we obtain these resources? We obtain these resources by utilizing appropriate mining and extractive metallurgical processes.
What is extractive metallurgy? Extractive metallurgy is the branch of metallurgical engineering that is associated with the separation of valuable minerals or metals from specific resources such as run-of-mine ores and recyclable materials as well as their recovery into saleable raw material products.
Extractive metallurgy consists of two main divisions:. First pdf from our extractive metallurgy class. Flag for inappropriate content. Related titles.
