Abstract
Apparatus is providing featuring a synthetic bead having a solid-phase body with a surface, and being configured with a predetermined electric charge so as to respond to a corresponding predetermined electric field; and a plurality of molecules attached to at least part of the surface, the molecules comprising a functional group selected for attracting and attaching one or more mineral particles of interest to the molecules. Some combination of the solid-phase body or the surface may be configured from a polymer. The polymer may be polyethylenimine. The polyethylenimine may be engineered or configured to be highly charged so as to be used to collect the mineral particles of interest and then manipulated through and by the corresponding predetermined electric field.
