Abstract: The corrosion of aqueous heavy pulps which contain ferrosilicon with between 8 and 20 weight % of silicon as a heavy medium and are used in the heavy media separation of minerals is inhibited. To this end, the heavy pulp is used in admixture with between 0.1 and 0.8 weight % of a carboxy-alkane-phosphonic acid of the following formulae: in which R stands for hydrogen or alkyl having from 1 to 4 carbon atoms, or
