1.(SIIL reserves tech right to change specifications with out notice consequent to improvements effected in the process).

3) Estimation of metallic iron is by "Indirect Bromine Methanol" method.

2. Chemical analysis indicated above refers to only magnetic fraction of material and not in combination with Char and other contaminants.

4) Degree of metallisation indicated refers to average for different grain size fraction with size tolerance of + or - 5% (five percent).
