Creating Iron HowStuffWorks

Liquid iron collects at the bottom of the blast furnace underneath a layer of slag. The blacksmith periodically lets the liquid iron flow out and cool. At this point the liquid iron typically flows through a channel and into a bed of sand. Once it cools this metal is known as pig iron. To create a ton of pig iron you start with 2 tons 1.8 ...

Iron element extraction miningtechnique - Great mining

MINING AND PROCESSING: Iron ore mining can be broadly divided into two egories namely 1 manual mining which is employed in small mines and 2 mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Iron Ore HowStuffWorks

Instead the iron heats up into a spongy mass containing iron and sili es from the ore. Heating and hammering this mass called the bloom forces impurities out and mixes the glassy sili es into the iron metal to create wrought iron. Wrought iron is hardy and easy to work making it perfect for creating tools.

How Is Iron Extracted From the Earth? -

Iron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however because iron does not occur naturally it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Iron Ore Smelting Process - Bright Hub Engineering

This pig iron is converted to wrought iron or processed into steel by several methods. This is the first article in a series on metallurgy where we will examine the processing of iron ore into different grades of steel. We start with the mining and preparation of the iron ore and shipping it to the smelter. The Mining of Iron Ore

What are the main methods of mining? American Geosciences ...

There are four main mining methods: underground open surface pit placer and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments. In-situ mining ...
