Sintering, as we wrote in a previous article, is the step between mining iron ore and steelmaking.Sinter is the primary feed material for making iron and steel in a blast furnace, and is made by mixing iron ore concentrate with several additives (such as limestone and silica to control the chemistry) and then igniting it at 1200°C in a continuous belt-fed furnace.
Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to …

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
