The chemical reaction that creates iron needs:

Raw Materials extraction

Metal minerals

ironCoal

limestone

heat

Raw Materials extraction

We get metal minerals, coal and limestone from mines around the world

furnaceRaw materials

Raw materials are introduced into the furnace with high temperatures

Slag

Iron cast

In order to obtain pure metal we need to transport the iron cast with specials containers and oxidize the mix with pure O2

specials containers

pure O2

Liquid metal is introduced into special moulds. Liquid metal fills the mould and get cold and rigid with a special shape.

Calc

Let’s study what is the metal environmental impact

You are going to be data analyst

Create a new open office calc file and copy this data:

Country CO2 emissions Energy consumed Mkw

Country CO2 emissions Tones Mkw

Spain 2000 100

France 1500 150

Germany 2500 50

Portugal 3000 75

England 3500 125

Now calculate the total amounts of CO2 and the Energy

Country CO2 emissions Tones

TOTAL

Create a graphic that explains which country consumes more energy or emits more CO2
