Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections. Figure: Schematic overview of an ironworks Iron ore extraction

The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom.

Figure 2 shows a schematic diagram of the experimental apparatus used, with its core part represented by a 50-mm-diameter horizontal reactor made of quartz glass. An electric furnace covering the whole reaction zone (including an Al 2 O 3 boat) was used for elevating and maintaining reactor temperature. The roasting temperature was set to 973 K (700°C) and 1273 K (1000°C), respectively.

Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making techniques classed as

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 0.5-1 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.
