Processed to separate Iron found in Iron Ores (iron oxide) - ANSWER-
PyroMetallurgy, ElectroMetallurgy, and HydroMetallurgy.
Pyrometallurgy - ANSWER-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 - ANSWER-process where iron ore is subjected to intense heat
in an electric furnace, thus separating the iron from impurities.
Hydrometallurgy - ANSWER-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: -
ANSWER-Oxidation
In civil engineering construction, epoxy-coated steel: - ANSWER-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 - ANSWER-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 - ANSWER-True
T/F
In civil engineering construction, epoxy-coated steel
Adds to the tensile strength of the steel used in reinforced portland cement
concrete - ANSWER-False
Iron and steel are both ferrous metals with the distinctions : - ANSWER-Steel is an
alloy whose base metal is iron
T/F
Iron is a lower-cost alternative to steel in civil engineering construction -
ANSWER-False
T/F
Steel is an alloy whose base metal is aluminum - ANSWER-False
T/F
Steel is an alloy whose base metal is iron - ANSWER-True
