Magnetic Separation of ferrous Metal ores by conditioning in multiple stages

摘要

Rreferido a process to separate at least a First material of a mixture comprising at least a First material and a Second material at least, which comprises at least the following steps: a) setting in contact of the mixture which comprises at least a First material and at least one according Do material with at least one Surface active substance,If appropriate in the presence of a Scattering medium, the Surfactant substance that binds with at least a First material; (b) where appropriate,Adding at least a Scattering medium to the mixture obtained in the step (a) to obtain a dispersion; (c) treatment of the dispersion of the step (a) or (b) at least one Hydrophobic Magnetic Particle so that the crowd at least a First material which at least its a The Surfactant is United and at least a Magnetic Particle; (d) separation of the agglomerate dAnd the step (c) of the mixture by applying a Magnetic Field to obtain a mixture M1 Exhausted and agglomerate agglomerate and repeating them in stages (a) to (d)
