ADDRESSING INFORMATION GAPS ON PRICES OF MINERAL

Iron Ore Iron ore is a bulk commodity that provides the ferrous content for steelmaking. The collective use of “iron ore” refers to several different types of deposits, which can be broadly grouped into “high-grade” and “low-grade” ores. High-grade ores of between approximately 50 to 65 percent iron are

Iron ore pricing explained | Metal Bulletin

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
