Abstract

The invention provides a preparation method for producing metal zirconium industrially and producing low-temperature aluminum electrolyte as byproduct, which comprises the following steps: A) aluminum and fluorozirconate are put in a closed reactor, inert gas is fed into the reactor after evacuation, the reactor is heated up to 780° C. to 1000° C. and then the mixture in the reactor is stirred rapidly; and B) after reaction continues for 4 to 6 hours, the liquid molten at the upper layer is sucked out to obtain low-temperature aluminum electrolyte, and the product at the lower layer is subjected to acid dipping or distillation to remove surface residue to obtain metal zirconium.
