Feb 28, 2019 The ore dressing production process is to convert the mined iron ore material into the iron ore concentrate. Also, in order to meet the demand of different ore concentrate products from back-end customers in the supply chain, the front-end mining production and mineral processing/dressing production should be coordinated. The upgrade of iron content in the ore to 68.54% and the drastic reduction in phosphorous and sulphur contents has thus rendered the Koton Karfe iron ore suitable for use as a super concentrate for the Aladja steel plant direct reduction iron making process.

In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal. In direct reduction, iron remains in solid state and the product is the so-called direct reduced iron (DRI). Generically, the iron ore products for ironmaking Iron is found mainly in iron ore in the form of oxides. To reduce iron ore to pig iron, modern technology adopts coke, coal, heavy oil, natural gas and other fuels in the blast furnace combustion, generating a lot of heat and reducing gas, creating the necessary conditions for iron ore reduction. In the past, pig iron was usually made at relatively low temperatures. The method is to place iron ore

Feb 23, 2013 Raw material preparation During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials from the iron content. This processing works to transform raw, mined iron ore into a concentrated
