C1, Metals and crude oil

HideShow resource information
What is a metal ore and how are they retrieved?
A rock containing a metal, or a metal compound, with a high enough concentration to makie it economically worth extracting. Retrieved by mining
1 of 16
Name the 3 methods of extraction
Electrolysis, reacted with carbon or hydrogen
2 of 16
How is iron extracted from its ore and what is the process at which oxygen is removed?
In a blast furnace and oxygen removed by reduction reactions
3 of 16
How is copper extracted and how it is purified?
Extracted by smelting and purified by electrolysis
4 of 16
Whatth process of phytomining?
Some plants dissolve copper compounds through their roots. The plants are burned to produce an ash with contains the copper compounds
5 of 16
What is the process of bioleaching?
Some bacteria absorbs copper compunds. They produce solutions called leachates, comtaining the copper compounds
6 of 16
How can copper be extracted from copper salt solutions?
By using iron scrapes.
7 of 16
Why are aluminium and titanium so useful? and how
Because they resist corrosion becaue they are covered in a thin layer of oxides and are lowdensity (lightweight for their size)
8 of 16
Why isn extracting titanium and aluminium very expensive?
Becauae it involves many stages and lage amounts of energy are needed
9 of 16
Name 2 things that aluminium is used for and 2 things that titanium is used for
A= Aircrafts and cooking foil T= Artificial joints and nuclear power stations
10 of 16
What are crude oils and what is the formula for them?
Hydrocarbons and CnH2n+2
11 of 16
What are alkenes and what does this mean?
They are saturated hydrocarbons so carbon atoms are joined by single bonds. They are unreactive apart from burning and combustion
12 of 16
What is distillation and when does it work?
A process at which pure liquids can be separated from mixtures of liquids and works when the liquids have different boiling points
13 of 16
What happens as you go up the fractional distillation column? Name 3 things
The hydrocarbons have- lover viscosity, l;ower boiling points and higher flamibility
14 of 16
Where do hydrocarbons with different boiling points condense in the fractional distillation column condense?
high= at bottom of column low= at top of column
15 of 16
What is the top and bottom of the fractional distillation column like?
Hot at the bottom and cold at the top
