Abstract
A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of a synthetic material such as polymer and the synthetic material is functionalized with molecules having a functional group for attaching mineral particles to the surface in a separation process. The synthetic beads can be placed in flotation cell containing a mixture of water, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.
