Iron Ore Pellets and Pelletization Process IspatGuru

26/11/2014 Pellets plants based on rich iron ore fines are rare and not very economical. The entire pelletizing process can be divided into two main segments of sub processes namely (i) the segment of the cold sub processes and (ii) the segment of the hot sub processes. The segment of the cold processes has the following sub processes. Slurry tank for storage of concentrated iron ore slurry from

Introduction to Iron ore Pellets and Pelletizing processes

23/02/2013 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. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is required for the pellet production. Suitable binder

The Fastmet is a continuous process which basically consists of a rotary hearth furnace where one or two layers of self-reducing iron ore pellets are placed. These self-reducing pellets are made from a mixture of iron ore concentrate, reductor (coal or coke), and binder. Unlike the other processes previously described, the Fastmet process uses a solid instead of a gas to reduce the iron oxide

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
