coke is on bringing higher reduction and lower sintering among the pellets. For the pellet mixed with nut coke, at the core, ∼25 vol.% of the material is observed in a network arrangement. The core structure consists of a wüstite matrix (10–20 vol.%) reinforced with the iron nuclei (5–15 vol.%). On the contrary, in the absence of nut coke, the pellet core is observed being hollow.

Charcoal Use in Chromite Pellets − Effect on Sintering ...
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. In this paper, coke substitution with charcoal in chromite pellet sintering is studied.

MANGANESE ORE SINTERING MISCONCEPTS AND FACTS
During sintering, the silica content in finished sinter increases to great extent leading to higher slag volume, higher Mn losses and higher power, so sinters are uneconomical. FACT • Oxygen loss during sintering is 9 to 10 % only (MnO 2 Mn 3O4). • Silica (SiO 2) addition through coke is 1 to % only.
