An apparatus for chlorination of molten magnesium chloride salts, comprising a shell lined with a refractory material and having the interior thereof formed by walls, a bottom and a cover. The lower portion of the shell walls is provided with chlorine inlet means whereas the upper portion has a melt feed inlet means and a chlorinated melt outlet means. The interior of the shell is so tapered downward that its clear opening, F.sub.1, at the level of the chlorine inlet means is not over 0.3 times the clear opening, F.sub.2, at the level of the melt feed inlet means and the chlorinated melt outlet means.

Apparatus for chlorination of molten magnesium chloride salts

Disclosed is an apparatus for chlorination of molten magnesium chloride salts, comprising a shell lined with a refractory material and having the interior thereof formed by walls, a bottom and a cover. The lower portion of the shell walls is provided with chlorine inlet means whereas the upper one has a melt feed inlet means and a chlorinated melt outlet means. The interior of the shell is so tapered downward that its clear opening at the level of the chlorine inlet means is not over 0.3 times that at the level of the melt feed inlet means and the chlorinated melt outlet means.

To produce magnesium and chlorine, a melt of anhydrous chlorides of magnesium, potassium and sodium is subjected to electrolysis. The molar ratio of potassium chloride to magnesium chloride in the initial mixture of chlorides ranges from 0.9 to 5.0 and the molar ratio of potassium chloride to sodium chloride in the melt ranges from 1.2 to 2.7 with the content of sodium chloride ranging from 19 to 38% by weight.

Process for electrolytically producing magnesium and chlorine from fused

The electrolyzer has a refractory-lined hollow shell divided into a group of electrolytic cells and a magnesium collecting cell by a vertical separator plate that is shorter than the shell. Steel cathodes shaped as frames embrace a graphite anodes arranged in groups. To convey magnesium from the electrolytic cells into a magnesium collecting cell, at least two passageways are provided, each of them being substantially at right angles to the graphite anodes and to the separator plate. The separator plate has through perforations situated below the electrolyte level. Each of the passageways is confined between the wall of the electrolyzer shell and the portion of the cathode that faces towards the magnesium collecting cell. The width of each of the magnesium conveyance passageways is a maximum of three times the width of the gap across the adjacent graphite anode and steel cathode in each electrolytic cell.
