§2.3 World: Mineral resources

Slide 1 - Slide

At the end of this lesson..

.. you know that it depends on the way of formation what types have evolved

.. you understand the difference in formation between ores and fossil fuels

.. you can indicate different resources by using maps

Slide 2 - Slide

What are mineral resources?

Slide 3 - Open question

What are mineral resources?

Sources we use that we win from underground

3 types:

1. Metals; iron, gold, lithium

2. Fossil fuels; coal, (crude) oil & gas

3. Various raw materials;salt, gravel, limestone

Slide 4 - Slide

What is the difference between mineral resources and raw materials

Slide 5 - Open question

Slide 6 - Slide

1. Metals

Examples: iron, aluminium, tantaal, indium, lithium, cupper, chrome, nikkel, lead, zinc, tin, gold, silver and platina.

Metals are extracted from ores (ertsen)

Slide 7 - Slide

What are ores?

Minerals in which we find metal and from which we can extract a mineral resource. it

So ....all ores are minerals, but not all minerals are ores .

Examples of ores are:

iron ore
cupper ore
silver ore
gold ore

Slide 8 - Slide

Slide 12 - Slide

What fossil fuels do you know?

Slide 13 - Mind map

Coalification:

Plants → peat → lignite → coal

3 fases:

2. Door sedimentatie komt het veen steeds dieper te liggen. Met de diepte stijgt de temperatuur. Daardoor kan het pakket veen omgezet worden in bruinkool.

3. Wordt de druk en vooral temperatuur nog hoger, dan zal bruinkool veranderen in steenkool en gaat het laatste water en gas eruit. Deze 3 fases samen worden het inkolingsproces genoemd.

1. Afgestorven planten komen onder water te liggen, in een moeras. Door zuurstof te kort, verteren de planten niet. Er ontstaat veen.

Slide 16 - Slide

Climate → tropical

Carboon: 350 tot 290 million ya

jaar gelede

position → around equator

→ Tropical swamp

Slide 17 - Slide

Formation oil

- dead plankton bottom sea

- covered by layers like sand

- high T and pressure turned it into crude oil

Together gas was formed

Slide 18 - Slide

3. Various mineral resources

Example: salt, gravel limestone

Slide 19 - Slide

Slide 20 - Slide

recycle the resources already used

Slide 21 - Slide

What will be left for you ?

Slide 22 - Slide

Which mineral resource will run out fastest?

OIL

RARE METALS

LEAD

ANTIMOON
