Application of a gas lift pump to a molten metal system was evaluated by determining the effects of liquid properties on the pumps transportation characteristics using a water bath, a glycerol solution bath, and a Woods metal bath. The flow in the gas lift pipe was in a "slug flow" regime when the pump was working. The critical gas flow rate, which is defined as the lowest gas flow rate required to transport the liquid, decreased with increase in the submergence and with decrease in pipe diameter in all systems. The density of the liquid strongly affected the lifted liquid volume whereas the viscosity had little influence on it. The empirical equation to predict the transportation of molten metal was derived using the slug flow model based on the corrected Nicklins equation. The model was able to reproduce the critical gas flow retes obtained by the experiment.
