Experiment 1 Gravimetric Determination of Iron as Fe2O3 You will use this gravimetric technique to determine the weight percent of Fe in an iron ore sample You will make at least three replie measurements which will allow you to determine so as to not lose any iron Digest the precipitate flocculate it by boiling for 5 min and
The study based on iron ore fines segregation clearly showed that utilisation of standard nonvertically sectioned blocks for ores with significant difference in particle densities can result in unacceptably high errors That was established for a broad range of particle sizes as the samples used for the study varied in size from 10 to 250 181m
Determination of iron using potassium dichromate Redox indiors Theory As an oxidant dichromate has some advantages over permanganate but as it is less powerful its use is much more limited It is obtainable in a state of high purity and can be used as a primary standard Solutions of dichromate in water are stable indefinitely
