Abstract Direct bubble–particle interactions are followed by measuring bubble sedimentation potential (BSP) and by visualization at a pendant bubble. Alumina and silica were selected as examples of positive and negative charge particles, respectively, at the test pH 6–7 along with a serpentine sample isolated from an ultramafic Ni-ore. Provided particle concentration was not too high, BSP could be measured and interactions followed. Alumina and serpentine hydrophobized by anionic surfactant… CONTINUE READING
