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.

Diaphragmless electrolyzer for producing magnesium and chlorine

The invention relates to magnesium-containing mixtures, in the form of granules of a particular shape, made by the introduction of a salt to liquid metal at a temperature of 670.degree.-720.degree.C, heated to a temperature of 670.degree.-730.degree.C, composed of metal chlorides and fluorides not reducible by magnesium, taken separately or in combination, and having an initial crystallization temperature below that of the granulated metal, and a density at the temperature of 670.degree.-730.degree.C equal to 0.95-1.2 of the density of the metal. The molten mixture is atomized by centrifugal force with subsequent cooling of the thus produced discrete particles by air flow. The mixture obtained in producing granules of magnesium or its alloys comprises in weight per cent: 65-97 of granulated magnesium, 0.3-16 of magnesium and alkali metal chlorides, 0.1-10 of one of the fluorides, up to 3 of alkaline-earth metal chlorides, and up to 6 of magnesium oxide. The above mixture can also comprise in weight per cent: 60-97 of granulated magnesium alloy, 0.3-16 of magnesium and alkali metal chlorides, 0.1-10 of one of the fluorides, 0.3-10 of alkaline-earth metal chlorides, and not over 5.0 of magnesium oxide.
