Introduction to Iron ore Pellets and Pelletizing processes. These forces responsible for the agglomeration of iron ore fines are generated in the balling disc due the rotational movement in the balling disc. When the solid particles come in contact with water, the ore surface is wetted and coated with water film.
Magnetic separation(6) Pelleting A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2"). Pellets are screened to meet the size specifiion, with undersized or oversized pellets crushed and returned to the balling drums.
The Minnesota Iron Ore Project, developed by Essar Steel Minnesota (ESML) and part of the Essar Group, is loed near Nashwauk, Minnesota, US. The project includes the construction of an openpit mine, a concentrator and a seven million metric tons per annum (Mtpa) iron ore pellet plant, which is
FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at 0.010.05% prior to balling, i.e. about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be

In pelletizing plants that operate with wet grinding to reduce the particle size of the ore prior to the balling/pelletizing process, it is necessary to dewater the slurry exiting the grinding mills to lower the moisture content in the ore. The pelletizing of iron ore normally requires from 8% to 10 % moisture depending on the ore characteristics.

Pelletizing has great importance in iron ore mining, ensuring optimal use of mineral reserves and increases the overall blast furnace efficiency. In general, the process involves two main steps, firstly the balling, where green pellets are formed with the addition of a binder to enhance agglomeration, induced by water and capillary forces formed

Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world''s highgrade competent iron ore resources.
balling drums. At the time, they were the largest iron ore balling drums in the world. Iron ore concentrates are fed with a binder to the balling drums, where the tumbling action agglomerates them into pellets about the size of marbles. The use of a balling drum increases the efficiency of the steel making process by
