History of Metals Timeline Infographic
Infographic: History of Metals Timeline. The development of civilisation has relied heavily on the discovery of metals. Prehistoric man used metals to build tools and weapons and as our knowledge of metallurgy has developed, metals have played an essential role in the advancement of agriculture, transport and arts and craft – forging the path to today's modern society.
IRON AND STEEL INDUSTRY
U.S. Steel's ten divisions reflected the diversity of steel products made at that time, including steel wire, steel pipe, structural steel (for bridges, buildings, and ships), sheet steel (which would go largely for automobile bodies in subsequent decades), and tin plate (once used for roofing shingles, it would increasingly go to make tin cans).
Iron and Steel in Colonial America - Flintriflesmith
Steel, of all other metals, is that susceptible of the greatest degree of hardness, when well tempered; whence its great use in the making of tools and instruments of all kinds." "Steel is made from the purest and softest iron, by keeping it

Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting. From sulfide ores Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation.
Steelmaking - Wikipedia
Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel .
Iron Ore: Sedimentary Rock - Pictures, Definition & More
Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
What are Some Uses for Iron? (with pictures)
· Wrought iron can be used for seating, fences, and other decorative purposes, while steel is often used in construction. Cast iron can be used in the kitchen. Other compounds that include this element are used in dyes, insecticides, water purification, and many other products.
From ore to steel – ArcelorMittal
In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel.
USGS Minerals Information: Iron and Steel
The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must ...
How stainless steel is made - material, manufacture, used ...
To make stainless steel, the raw materials—iron ore, chromium, silicon, nickel, etc.—are melted together in an electric furnace. This step usually involves 8 to 12 hours of intense heat. Next, the mixture is cast into one of several shapes, including blooms, billets, and slabs.
Steel bar | RuneScape Wiki | FANDOM powered by Wikia
A steel bar is a bar of metal, refined through the Smithing skill by smelting an iron ore and 2 pieces of coal in a furnace, requiring 30 Smithing and granting 17.5 Smithing experience.. A steel bar can be forged on an anvil to create steel weapons and armour, granting 37.5 Smithing experience per bar used.A list of steel items that can be smithed from steel bars and the Smithing levels ...
Creating Iron | HowStuffWorks
The third option for pig iron is to push the refining process even further and create steel, which we'll examine on the next page. Iron Advantage Between the 15th and 20th centuries, some countries had an industrial leg up on the competition due to the availability of iron ore deposits.
Iron Ore Processing for the Blast Furnace
Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low -grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled
How steel is made - a summary of a Blast Furnace
Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels. Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.
How iron is made - material, manufacture, making, history ...
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.
DF2014:Metal - Dwarf Fortress Wiki
Decreased fuel consumption if making the alloy directly from ores (e.g. bronze requires only one smelter task to make 8 bars from 2 ores). The number of bars used to create an alloy always equals the number of bars produced: the number of bars input equals the number of bars of output.

Steps in the Modern Steelmaking Process
Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone. Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel production.
