The behaviour of glass beads and polyethylene pellets as the extra bacteria support in the fine black shale ore in the column bed bioreactor was compared. Capillary rise experiments enabled the calculation of the contact angle and the surface free energy of glass beads and polyethylene pellets. The results showed that the support material made up of polyethylene pellets yielded a higher copper extraction, which could be explained by conditions favourable to cell adhesion on the polyethylene surface.
