The flotation test for actual ore was carried out in XFG-3L flotation cell. The amount of ore samples in each experiment was 1000 g. The concentrates and tailings obtained by flotation test were dried, weighed and element content analyzed, and the grade and recovery were calculated. The closed-circuit flotation flowsheet was shown in Fig. 4.

More DetailsSurface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows heavier than water i.e., denser than water objects such as razor blades, insects (e.g. water striders), to float and slide on a water surface without becoming even partly submerged. At liquid–air interfaces, surface tension results from the greater ...
