Separation Techniques | Classifiion of Matter
Magnetic Separation. Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. Magnetism is ideal for separating mixtures of two solids with one part having magnetic properties.

Crushing and milling | Mining of mineral resources ...
Iron ore, coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.
Iron ore mining and dressing
Jun 21, 2018 · Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.
Economic Iron Bearing Minerals
Aug 03, 2012 · Almost all the iron ore that is mined globally will contain the minerals outlined in this article. Differentiating an Ore and a Mineral. It is important at this stage to distinguish between an iron ore and an iron mineral. An ore is the quantity of a mineral resource that can be extracted and is economically viable and legal.
Ironmaking 101 – From Ore to Iron with Blast Furnaces ...
Oct 10, 2017 · Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.
