"Gallium is found throughout the crust in minerals like bauxite, germanite and coal. Used in semiconductor production. It us used in making LED's (light-emitting diodes) and GaAs laser diodes. The price of 99.99 % pure gallium ingot is 930.40 € for 500 g."
Even if only small amounts of gallium needed to be used it would have to be recovered. For 350 pounds of aluminum, if only 5 grams of gallium was needed as a catalyst, the cost of the gallium alone would be almost $20 USD unless it could be recovered each time. The process of extracting isolating and processing 5 grams of gallium from a mass of about 160,000 grams of aluminum compound to make more pellets would not be easy to accomplish.
