End products made from this type of iron ore are also of higher quality than that produced from hematite ore. The former has fewer impurities, making it a premium product that can be sold to steelmakers for higher prices. In this way, the elevated cost of processing magnetite ore can be balanced out. Ore bearing rock is reduced by blasting into
Malcolm Tatum Raw ore deposits have to be crushed and processed. The processing of iron ore is a task that involves taking the raw ore and preparing it for use in the creation of a number of different iron products. There are actually several different processes that may be used to aid in this conversion of the raw ore into useful iron components

Introduction. Iron making evolved over a few thousand years. Using the ancient bloomery method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the direct process. By the 1100s water-powered hammers replaced

Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F))
