Abstract
The present paper highlights the potential of high intensity power ultrasound in iron ore beneficiation in reducing alumina, silica and phosphorous from Noamundi as well as Joda iron ores of M/s Tata Steel Ltd. This will ultimately lead to improve productivity and reduce coke rate of blast furnaces/sinter plants. It has been experimentally observed that applying 20 kHz frequency ultrasound for 5 min can bring down the percentage of alumina and phosphorous content from 1·720 and 0·050% to 1·120 and 0·048% respectively in the case of Noamundi iron ores; whereas in Joda iron ores, alumina was reduced from 2·25 to 1·65% and phosphorous from 0·089 to 0·05%.
