Mar 21, 2015· The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

Aug 31, 2017· Sintering requires high temperatures, which is generated by burning carbon‐bearing materials. Usually, coke is used as a fuel in chromite pellet sintering, which results in SO X and CO 2 emissions. Using low‐sulfur biofuel to substitute coke is an attractive technique for reducing SO X and CO 2.
