Molten corrosive metals such as aluminium are treated, especially for purification, by injecting of gases such as chlorine or nitrogen. This gas-treatment plant comprises a gas-treatment device immersed in a part of a furnace containing molten metal; an electromagnetic pump, situated above the gas-treatment device, stirs the mixture of gas and metal by counter-pressure operation and slag is formed in a decanting tank.
