Abstract
A system includes a collection processor configured to receive tailings of a flotation process, the tailings having mineral particles of interest; and at least one collection apparatus located in the collection processor. The collection apparatus has a collection surface configured with a functionalized polymer having molecules with a functional group that attract the mineral particles of interest to the collection surface. The flotation process has scavenger circuits that provide scavenger circuit feeds having scavenger tails. The system features enhanced scavenger circuits having the collection apparatus located in the collection processor and configured to receive the scavenger circuit feeds and provide enhanced scavenger circuit feeds having enhanced scavenger tails and enhanced scavenger concentrate for further processing by the system.
