Iron ores are rocks and minerals from which metallic iron can be extracted. The main iron ores are hematite and magnetite. Hematite and magnetite are iron oxides that have been mined for centuries to produce steel and iron products. There are different forms of processed iron - pig iron has a high carbon content and is very brittle; wrought iron is characterized by its fibrous appearance and is more malleable and ductile than cast iron; cast iron contains more than 2% carbon and is used to produce parts like bridges, balusters and fences that require strength but will rust easily over time.

IRON ORES
FERROUS METALS ARE THOSE WHICH CONTAIN IRON, WHILST NON FERROUS METALS DON’T HAVE ANY IRON CONTENT.
Metals used for architectural purposes Lead uses Tin uses Steel uses
Iron ore Sedimentary rocks Iron ore deposits Iron + oxygen (in marine or fresh water) Hematite (Fe2O3) Magnetite (Fe3O4) These iron ores have been mined to produce almost every iron and steel object that we use today
Manufacturing of Iron ores
IRON ORES
Iron • Forms of iron : Wrought iron Cast iron Steel alloy
PIG IRON • High carbon content, typically 3.5–4.5% • Very brittle, soft, ductile, magnetic • Has high elasticity and tensile stress • Made by smelting iron ore
IRON ORES
Wrought iron • Purest form of iron • Characterized by fibrous appearance • Highly malleable, softer and more ductile compared to cast iron • High tensile strength, high resistance to fatigue
CAST IRON • Cast iron is a group of iron-carbon alloy with a carbon content greater than 2%. • Cast iron is made by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants. • It is more often melted in electric induction furnaces or electric arc furnaces. After melting is complete, the molten cast iron is poured into a holding furnace or ladle. Alloying elements Grey cast iron White cast iron Malleable cast iron Ductile cast iron
The Iron Bridge Use of Cast iron and wrought iron Cast iron fencing Railing
Cast iron Wrought iron Pig Iron Carbon content 2-4% 0.08% 3.5-4.5% Main properties 1.Contains multiple constituents 1.Purest form 2.Tough,malleable 1.Treases of impurities of sulphur, phosphorus, manganese etc 2.Hard form of iron, brittle Uses Bridges, balusters, Columns, fences, structural connector in buildings Withstands shocks without permanent injury so used in chains, crane hooks, nail, bolt, wire, gates etc Water pipes, sinks, storage tanks, railings, cylinder, sewers, these parts rust easily
