Abstract
The invention provides the use of an iron/silicon/phosphorus-alloy containing between 8 and 25 weight % of silicon and between 0.3 and 2.5 weight % of phosphorus as heavy medium for making heavy pulps for the heavy media separation of minerals.
Claims6
Heavy pulp composition consisting essentially of water and a water-suspended metal powder consisting of particles with a size substantially between 0.001 and 0.4 mm for the heavy media separation of minerals, wherein the said metal powder is a pulverulent alloy having a density between 6.3 and 7.2 g/cc and consisting essentially of between 8 and 25 weight % of silicon, between 0.3 and 2.5 weight % of phosphorus and between 0.02 and 2 weight % of carbon, the balance being substantially iron, and the pulp density ranging between 2.0 and 3.9 g/cc.
