Abstract: HEAVY PULPS FOR THE FLOAT-SINK DRESSING OF MINERALS Heavy pulp for the float-sink dressing of minerals. The heavy pulp consists substantially of water and has pulverulent smooth and spheroidal heavy medium alloy particles suspended therein. The heavy medium alloy consists more particularly of 60 up to 70 weight % of nickel, 25 up to 35 weight % of copper, 3 up to 8 weight % of sulfur, and impurities originating from alloy preparation.

Abstract: PROCESS FOR INHIBITING THE CORROSION OF HEAVY PULPS FOR HEAVY MEDIA SEPARATION OF MINERALS 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: or in which R stands for hydrogen or alkyl having from 1 to 4 carbon atoms, or or or

Abstract: Prodn. of compact, smooth, corrosion-resistant ferrosilicon particles for use as a weighing suspension in the float-sink processing of ores is improved in that irregularly shaped ferrosilicon particles are passed in an inert gas stream through an electric arc or plasma jet, whereby the particles are melted at least superficially and rounded off. Subsequently the particles are passed through a cooling zone, and then collected in, e.g., a cyclone. The inert carrier gas is pref. H2, He, Ar, N2 or their mixts.
