At 1000 C, the metallization degree increased to about 30% 22 during the isothermal step so that the recovery increased to 53% for the nuggets resulting from the temperature pattern D. Temperature pattern D with an initial temperature of 1000 C seems to be the optimum temperature pattern for achieving high iron recovery in the form of nuggets.
