The raw iron ore sample were initially coarsely crushed to the size fraction of −50 mm and then classified to various size fractions by using a set of sieves. The sampling scheme for the mass balance of 500 iron ore particles was carefully considered based on the mass balance principle in mineral processing [[29], [30], [31], [32]].
