In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom. A second heat treatment, in another (converter) furnace, is necessary to remove the iron from the matte.
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

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, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
the process for obtaining iron from its ore · Rock salt jaw crusher are typically used as primary crushers, or the first step in the process of reducing rock. . and soft ores with less than 300MPa compressive strength, such as pebble, calcite, granite, quartz, concrete, dolomite, bluestone, iron ore, limestone, iron ore, coal gangue,.
Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy to work, making it perfect for creating tools.
The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being disposed of and the molten iron being poured into molds were it solidifies, now being in the form of pig iron. ...

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.

The pig iron was too brittle to be used for most things, so inventors started working on ways to toughen the pig iron. One of the ways pig iron is made tougher is by remelting the pig iron and burning off the remaining carbon. A blast of hot air is blown through the pig iron, which results in stronger forms of iron, cast and wrought iron.

It consists of several distinct steps. ... The blast holes are usually vertical but can be inclined for obtaining better blasting results.
Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steelmaking process. Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.
