Pelletization is a convenient way to manage the separation of incompatible drugs. Pellets offer reduced variation in gastric emptying rate and intestinal transit time. Pellets disperse freely in G.I.T. and invariably maximize drug absorption and also reduce peak plasma fluctuation 12. Pelletization solves the problem of taste masking.
Nov 26, 2014· Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.

Further, high alumina hematite pellets like Noamundi ore pellet shows very high RDI,12) which requires MgO bearing flux addition. There-fore, it is necessary to optimize the pellet chemistry and maintain suitable operation condition to get the advantage of
Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.
