This invention relates to an improved mould for casting a standard Magnesium ingot. The mould is constructed so as to minimize the surface area of the molten Magnesium which is exposed to the surrounding air. This significantly reduces the reliance on costly or harmful gases typically used in the, casting process. The vertical mould which is internally tapered has an open , top, and a closure at the bottom thereof. The ingot is easily removed from the mould, when said closure is opened. The mould is adapted for use as part of an automated process employing a cyclic conveyance system for efficiently producing Magnesium ingots from recycled scrap Magnesium.
