Abstract

See full text

A process for concentrating graphite particles comprising a) providing a feedstock which contains the graphite particles and an undesired material, b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the graphite particles, and c) separating the agglomerates from the loaded feedstock by a magnetic field which results in isolated agglomerates.
