Answer:
I can't just say one thing they are use for many things
Explanation:
Uses of iron :-
- It is used to manufacture steel and also used in civil engineering like reinforced concrete, girders etc.
- Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese.
- These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels.
- Cast iron contains 3–5% carbon. It is used for pipes, valves, and pumps.
- Iron catalysts are used in the Haber process for producing ammonia.
- Magnets can be made of this metal and its alloys and compounds.
Different types of coal have different uses.
Steam coal - also known as thermal coal - is mainly used in power generation.
Coking coal - also known as metallurgical coal - is mainly used in steel production.
Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries. Several chemical products can be produced from the by-products of coal. Refined coal tar is used in the manufacture of chemicals, such as creosote oil, naphthalene, phenol, and benzene. Ammonia gas recovered from coke ovens is used to manufacture ammonia salts, nitric acid and agricultural fertilisers. Thousands of different products have coal or coal by-products as components: soap, aspirins, solvents, dyes, plastics and fibres, such as rayon and nylon.
Coal is also an essential ingredient in the production of specialist products:
Activated carbon - used in filters for water and air purification and in kidney dialysis machines.
Carbon fibre - an extremely strong but light weight reinforcement material used in construction, mountain bikes and tennis rackets.
Silicon metal - used to produce silicones and silanes, which are in turn used to make lubricants, water repellents, resins, cosmetics, hair shampoos and toothpastes.
