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 Hyd ... roMetallurgy. 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 T/F 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 - ✔✔- True T/F In civil engineering [Show More]
