Cold bonded pelletization of iron ore fines using ordinary portland cement binder is emerging as a potential energy saving agglomeration process for proper utilization of Indian iron ore fines. The possibility of substituting ordinary portland cement/clinker by cheaper low grade Indian granulated blast furnace slag is investigated.

fraction of an iron ore. Iron ore tailings are the waste generated from iron ore industry after process. It is a very fine aggregate residue resulting from the extraction of iron from iron ore. 3 METHODOLOGY Casting of cement concrete blocks with various proportion of iron ore tailing.
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements.
As a kind of grinding ball mill equipment, widely used in the processing of fluorite ore, limestone, iron ore, fly ash, gypsum, quartz, cement and other minerals, used in ore dressing process without ball mill, ball mill and classifier, crusher, magnetic separator, flotation machine, such as equipment of corresponding use, jointly promote the application of mineral aggregate mill ...
Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steelmaking process, a stronger, lighter material results (steel). Steel is used in almost all modern buildings, automobiles, aircraft and appliances. ... How is Iron Made Into Steel?
· Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of
Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal, oil, gas, coke and/or various waste materials.

The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag making process and its corresponding benefits with respect to the enhanced cementitious properties of the slag. Grinding slag for cement replacement requires only about 25 percent of the energy needed to manufacture Portland cement.
metal on the basis of directly charged iron ore fines, and coal as the reductant and energy source. A key feature of the FINEX® Process is that iron production is carried out in two separate process steps. In a series of fluidizedbed reactors, fine iron ore is reduced to direct reduced iron.
