摘要： An electrolytic process is provided for the recovery of lithium values from a molten salt bath containing MgCl.sub.2, CaCl.sub.2, NaCl, KCl and LiCl. The salt composition in the molten state is subjected to the sequential depletion by electrolysis of the elements Mg, Ca, Na, respectively, either in substantially the elemental form or as an alloy thereof under multistage operating conditions to provide a depleted salt composition comprised substantially of the binary LiCl-KCl from which lithium is subsequently recovered by electrolysis as lithium per se or an alloy of Al/Li.

摘要： A process is provided wherein metal granules coated with a polymerizable oil are heated, while being mechanically mixed, to a polymerizing temperature to convert the oil coating to a varnish and the varnish coating thereafter heated to a higher temperature to decompose at least partially the varnish to carbon, thereby producing a carbon coating strongly bonded to the metal granules. The temperatures employed are below the melting point of the metal granules. The coating is preferably applied to magnesium, aluminum or alloys thereof for use as addition agents in steel, e.g., desulfurizing or deoxidizing agents, and may contain fine particles of at least one calcium compound.

摘要： Magnesium oxide is chlorinated in molten impure magnesium chlorine with chlorine gas by adding ferrous chloride to magnesium chloride brine, drying the brine, adding a mixture of calcined petroleum coke and charcoal to the dried brine, melting the product and chlorinating the formed melt. Ferrous chloride is added in amounts sufficient to provide from about 1.0% to 2.2% by weight of iron in the dried product. A highly reactive carbon source is added in amounts of from about 0.8 to 2.3% by weight and a carbon source that is less reactive than the highly reactive carbon source is added in amounts ranging from about 0.8 to 2.3% by weight of dried brine. Iron levels in the magnesium chloride melt may be adjusted upwardly by addition of a mixture of iron oxide and charcoal.A melt cell characterized by side entry electrodes disposed at angles from 40.degree. to 50.degree., an arched roof configuration, and an improved electrode refractory and ceramic sleeve construction is used to chlorinate the magnesium.
