This fine material is concentrated by magnetic log-washers in which the final separation is made. The concentrate produced by these machines is then dewatered by the use of continuous filters in the tank of which the fuel for sintering is mixed. The filter cake is conveyed directly to the sintering plant, where the ore is agglomerated.

Growth of steel industry with depleting resources of high grade ores have led to a very strong demand for both pelletising and sintering of iron ores. Process objective is to transform fine …
Beneficiation follows and is the initial attempt at liberating and concentrating the valuable mineral from the extracted ore. After the beneficiation step, the remaining material is often physically and chemically similar to the material (ore or mineral) that entered the operation, except that particle size has been reduced.
Iron Ore: Mineralogy, Processing and Environmental Sustainability, Second Edition covers all aspects surrounding the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of the global infrastructure. The book explores new ore types and …
After beneficiation & sintering / pelletization of iron ore, beneficiation and sintering of manganese ore fines attracted technology experts due to massive expansion in manganese based ferro-alloys. Fast depleting high grade lumpy manganese ore deposits made the beneficiation and sintering all the more wanted solution.
Sintering works through the diffusion of atoms across particle boundaries before fusing together into one piece under the influence of pressure and/or heat. While this process can occur naturally for mineral deposits, it is also widely used by a range of industries to manufacture items from materials including ceramics, metals and plastics.
Cold sintering: Uses a transient solvent and pressure to consolidate polymer powders into a solid mass. Materials Used in Sintering. As a wide spectrum of techniques, sintering finds application in a huge range of materials. These are listed below: 1. Metals. A wide range of metals can be used in sinter processes of several types.
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared …
Agglomeration of iron ores is the iron ore pretreatment process in which the powdery iron ore that cannot be directly fed into a blast furnace experiences high-temperature solidification by sintering process and pelletizing process or low-temperature solidification by pelletizing process and briquetting process to generate the rich ore material that meets the …
