Alloying Flashcards
Pure metals are at it’s highest
Metling point
Lattice structure
Displaces atoms and this affects size
Atomic number is proportional to
Smaller intestiational bigger substitutionall
Larger grain size has higher
Ductility
Lower grain size has higher
Strength
Ores are an example
Compounds (oxides and sulfides)
4 main methods of mining
Surface(open pit), placer( separating from mineral s in sand or gravelfrom sand ,underground, in-situ inside to get purest form)
Go to deeper deposit. Most expensive
Underground
Used to sift out valuable metals. Sediments. Beach snads
Placer
Dissolves the ore resource in place. Pumps the liquid to surface. Primarily for uranium
In situ
Earthly impurities found in rock with ores
Gangue
Ores is cleaned to get the fewest impurities
Concentration
Putting sulphide away with water. Ore is purified at bottom
Froth separation/ flotation
Magnetic separation
Most effective after crushing stands fir
TNT( tri nitro toluene)
