Recycling of iron & steel - SlideShare

Economic Facts of Iron & Steel Recycling. •Almost 40% of the world's steel production is made from scrap. •Every ton of recycled steel can help saving 1.4 ton of iron ore. •Conversely, a steel can land-filled will take 100 years to vanish. •Steel is the most recycled material on earth!

Explain how iron ore is refined to make steel? | Study

Answer and Explanation: 1. When making steel, the mined iron owe is smelted in a blast furnace to remove impurities and add carbon. The process occurs when iron ore, limestone, and coke are ...

Iron Ore can be found all over the world but in Australia the main deposits of this mineral can be found in the Western Australian Pilbara region. The mountains that this iron comes from are known as fold mountains these mountains form the range known as the Hamersly range. In 2001 58.7% of all metals exported was iron this is significant because it made the state a profit of over a billion ...

Iron making - SlideShare

Pig iron Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content, typically 3.5– 4.5%, which makes it very brittle and not useful directly as a material except for limited ...

Chapter 6 Copper Production Technology

ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.

The Making of Iron & Steel

2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).

Steelmaking and Refining | Introduction to Chemistry

Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are …

Iron Ore Mining PowerPoint PPT Presentations - PowerShow

Iron Ore Mining Market Size, Competitive Landscape, Regional Outlook and Driving Factors Analysis - Iron ore mining is the process of extraction of iron mineral from the various mineral deposits and rocks present in mines. The rocks are extracted and undergo the smelting process so that the melted iron can be poured into molds so that various iron-based products are formed.

12.3 Primary Copper Smelting

(1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Production of iron and steel - SlideShare

4/27/2015 15 Iron ore Common iron ores include: Hematite - Fe2O3 - 70 % iron ( a common iron ore) Magnetite - Fe3O4 - 72 % iron Limonite - Fe2O3 + H2O - 50 % to 66 % iron Siderite - FeCO3 - 48 percent iron To create a ton of pig iron, you start with 2 tons of ore, 1 ton of coke and half-ton of limestone. The fire consumes 5 tons of air.

How is Iron Refined from Ore? (with pictures)

Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires ...
