A slurry of particulate ore material is concentrated to form a smeltable concentrate on a re-concentrator table arranged to separate concentrate ore at a concentrate discharge from middlings and tailings. The table is set such that the concentrate forms a smeltable concentrate and thus at least the middlings contain significant quantities of the concentrate to be collected. The ore to be concentrated is fed to a feeding system including a bin in batch form and carried from the bin by a screw through a screen to the table. The table is operated in processing of the batch for a first period of time during which both the middlings and tailings are returned to the feeding system for recirculation to the table. The period of time is such that the material is circulated over the table repeatedly to separate out the concentrate. After the first period, for a second period, the table is operated while directing at least the tailings and possibly the middlings to discard so as to reduce the batch sufficiently to receive the next batch.
