procedure for bulk density determination was based on the work of Lipton (2001) 'Water Dis-placement Method 4'. In this method, the bulk density is calculated from the relationship between the sample weight and the water displa-cement caused by the sample immersion in a graduated container. (2) In the second step, bulk density was estimated

The composition of Blend B given in Table 1 can be considered to be the base case. To reduce bed bulk density a very porous ore (VPO) was introduced into this blend. As the chemical composition of VPO is very similar to the low-alumina pisolite ore in the blend (), directly substituting VPO for this pisolite ore gave no significant changes in sinter chemical composition.
