Sintering: A Step Between Mining Iron Ore and Steelmaking

Sintering: A Step Between Mining Iron Ore and Steelmaking

 · Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel.

Different Types of Iron Ore

Different Types of Iron Ore

 · Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Raw materials

Raw materials

 · Scrap metal. Iron and steel scrap is used as a secondary raw material, both for scrapbased and orebased steel production. The scrap is sorted into different classes and the steel plants utilise a mixture of the types of scrap that best suit the steel that it is intended to produce. Read more about scrap classes in the section on Recycling.

 · The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Iron Recycling

Iron Recycling

recycling iron conserves energy and saves landfill space. It takes less energy to create iron and steel from recycled iron than from iron ore. Using recycled metals also helps mitigate some of the negative effects of the mining process, which is energy and waterintensive and does lasting damage to the areas surrounding mines.

Mineral Processing Wastes

Mineral Processing Wastes

For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense. For the most part, lead and zinc ores are found in limestone and dolomite rock, so the waste rock from processing these ores will have characteristics much like other carbonate aggregates.

Biomining: metal recovery from ores with microorganisms

Up to now, biomining has merely been used as a procedure in the processing of sulfide ores and uranium ore, but laboratory and pilot procedures already exist for the processing of silie and oxide ores (, laterites), for leaching of processing residues or mine waste dumps (mine tailings), as well as for the extraction of metals from industrial residues and waste (recycling).
