摘要： A process for the preparation of vanadium, vanadium alloys, or vanadium compounds from vanadium-containing slags by heating these slags in a reaction furnace under the influence of sodium carbonate and oxygen at a temperature between 600 DEG and 800 DEG C and subsequently leaching the reaction product with water so that the resultant vanadate enters into solution and is then processed to the desired vanadium product in a manner known per se, characterized in that an amount of sodium carbonate is used at which the ratio (quantity by weight of sodium carbonate/quantity by weight of vanadium calculated as vanadium pentoxide) IS AT LEAST 1.1 AND DOES NOT EXCEED 4.

摘要： 1,142,054. Vanadium, tungsten, molybdenum and niobium chlorides. BRITISH TITAN PRODUCTS CO. Ltd. 4 Oct., 1967 [17 Oct., 1966], No. 46412/66. Heading C1A. Vanadium is recovered from vanadium containing solids by suspending the solids in a liquid which dissolves chlorine and treating with chlorine under superatmospheric pressure to produce vanadium chloride, e.g. as oxychloride. Preferred pressures are 5 to 250 p.s.i.g. and preferred temperatures are 20 to 250 C. The solids may be 5 to 60% by weight of the suspension. The process is especially suitable for recovering vanadium from titanium containing sludge from the purification of TiCl 4 with mineral oil. The preferred liquid for the process is TiCl 4 . Tungsten, molybdenum and niobium, if present, may also be recovered as chlorides.
