AN IMPROVED PROCESS FOR PRODUCTION OF HIGH PURITY MAGNETITE FROM HEMATITE PARTICLES COLLECTED AS STEEL PLANT WASTE THE PROCESS

摘要

The invention relates to an improved process for production of high purity magnetite from hematite particles collected as steel plant waste the process comprising the steps of: i) charging hematite particles into a fluidized bed reactor and raising the temperature of the reactor in the range of 400-750 ºC, ii) passing coke oven gas through the reactor for fluidization and allowing reduction reaction at atmospheric pressure for a period ranging between 60 to 240 min and cooling the product using the same gas to obtain magnetite, iii) and Collecting the magnetite by known method.
