METHOD FOR PREPARING AN ELECTROLYTE AND AN ELECTROLYTE REPLENISHMENT SYSTEM DURING ALUMINUM ELECTROLYSIS PROCESS

摘要

The disclosure provides a method for preparing an electrolyte and an electrolyte replenishment system during an electrolytic process. The method includes the following steps: Step A: placing aluminum in a reactor, vacuumizing the reactor and feeding an inert gas, heating the reactor to 700-850 degrees centigrade, and adding one or more of potassium fluozirconate, potassium fluoborate, sodium hexafluorozirconate and sodium fluoroborate; and Step B: stirring the reactants for 4-6 hours and extracting the upper molten liquid to obtain an electrolyte replenishment system during an aluminum electrolysis process. The disclosure has the following beneficial effects: when used in the aluminum electrolysis industry, the electrolyte system provided herein can be directly used as an aluminum electrolyte or a replenishment system in an electrolyte without changing existing electrolysis technology to significantly reduce an electrolysis temperature during an aluminum electrolysis process.
