ABSTRACT:
A method of continuously extracting magnesium by subjecting chloride electrolytes to electrolysis consists of enriching an electrolyte in magnesium chloride and refining the same, mixing the enriched electrolyte with the recycled electrolyte containing the magnesium extracted in electrolytic cells, separating the magnesium from the resultant electrolyte, dividing the electrolyte into two flows of which one is fed to be enriched, while the other is delivered to a bank of electrolytic cells series-connected by conduits, delivering the recycled electrolyte containing the extracted magnesium for mixing with the enriched electrolyte prior to the step of separation, accumulating the magnesium and withdrawing the same from the process. In a processing line used for practicing the above method preferably utilized is a multiple-cell flow apparatus comprising a chamber for enriching the electrolyte in magnesium chloride the wall of which having a passage for establishing communication with a chamber for separating magnesium from the electrolyte through a corresponding passage in the wall thereof as well as a chamber for dividing the electrolyte into flows, the chamber for dividing the electrolyte into flows being disposed between said chambers for enriching and separating the electrolyte. In the processing line practicing the method may preferably be used a multiple-cell flow apparatus comprising a chamber for enriching the electrolyte in magnesium chloride the upper part of the wall of the chamber has a passage for establishing communication with a chamber for separating magnesium from the electrolyte through a corresponding passage in the wall thereof as well as a chamber for dividing the electrolyte into flows, the chamber for dividing the electrolyte into flows is disposed between said chambers for enriching and separating the electrolyte.
