Materials CE 200 Seminar Final Exam Quiz 4 - Metals and Soils with Complete Solutions
Processed to separate Iron found in Iron Ores (iron oxide) - ✔✔- PyroMetallurgy,
ElectroMetallurgy, and HydroMetallurgy.
Pyrometallurgy - ✔✔- AKA Smelting
melting by heating the iron ore in a blast furnace, reducing the iron, and fusing it
in the presence of a flux, like ground limestone
Electrometallurgy - ✔✔- process where iron ore is subjected to intense heat in
an electric furnace, thus separating the iron from impurities.
Hydrometallurgy - ✔✔- process where iron is dissolved in an aqueous solution,
thus separating from impurities, and then precipitated
number of the electrons in their valence shells makes metals more prone to: -
✔✔- Oxidation
In civil engineering construction, epoxy-coated steel: - ✔✔- Is used to protect
reinforcing steel from attacks by salty and acidic fluids absorbed by the portland
cement concrete
T/F
In civil engineering construction, epoxy-coated steel
Is commonly used in steel high-rise construction to make the steel bend and
deform less during serious fire incidents - ✔✔- False
