Alloying

Question 1

Pure metals are at it’s highest

Answer 1

Metling point

Question 2

Lattice structure

Answer 2

Displaces atoms and this affects size

Question 3

Atomic number is proportional to

Answer 3

Smaller intestiational bigger substitutionall

Question 4

Larger grain size has higher

Answer 4

Ductility

Question 5

Lower grain size has higher

Answer 5

Strength

Question 6

Ores are an example

Answer 6

Compounds (oxides and sulfides)

Question 7

4 main methods of mining

Answer 7

Surface(open pit), placer( separating from mineral s in sand or gravelfrom sand ,underground, in-situ inside to get purest form)

Question 8

Go to deeper deposit. Most expensive

Answer 8

Underground

Question 9

Used to sift out valuable metals. Sediments. Beach snads

Answer 9

Placer

Question 10

Dissolves the ore resource in place. Pumps the liquid to surface. Primarily for uranium

Answer 10

In situ

Question 11

Earthly impurities found in rock with ores

Answer 11

Gangue

Question 12

Ores is cleaned to get the fewest impurities

Answer 12

Concentration

Question 13

Putting sulphide away with water. Ore is purified at bottom

Answer 13

Froth separation/ flotation

Question 14

Magnetic separation

Question 15

Most effective after crushing stands fir

Answer 15

TNT( tri nitro toluene)

Question 16

involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time with a chemical solution to dissolve the sought-after metals, and collecting the blank as it percolates from the base of the heap.

Answer 16

Bayer’s procces( leaching)

Question 17

Interstial alloy

Answer 17

when a metal usuaaly of a smaller aotmic number moves in between the larger atoms of the base metals.

Question 18

Substianial alloy

Answer 18

When a metal usually of a simialr atomic number repalces atoms in the base metal.

Question 19

Interstial alloys typically

Answer 19

due to the Different sized atoms the crystal lattice is much more rigid. therefore it tends to be less ductile, and less malleable. but also has increased hardness

Question 20

Four different concentrations methods

Answer 20

Froth separation, gravity, electromagnetic, and leaching

Question 21

Isolation of metals

Answer 21

Reduction by carbon, electrolysis, and other metals

Question 22

Purifaction of metals

Answer 22

Smelting, Calcination, Zone refining, Liquation, Distillation, Vapor phase refining,
