    • A process and system for recovering titanium dioxide and other value metals from a titanium bearing solid is disclosed. The process includes leaching the solid in hydrochloric acid to produce a leachate comprising undissolved solids and a leach solution comprising the titanium dioxide and the value metals, wherein the hydrochloric acid concentration is maintained above a value required to maintain the titanium dioxide and the value metals dissolved in the leach solution at atmospheric pressure. The leachate is separated into the leach solution and the undissolved solids. The concentration of hydrochloric acid concentration in the leach solution is reduced to recover titanium dioxide by hydrolysis and precipitation to produce a titanium dioxide rich slurry. In a preferred embodiment, HCl is recovered with a matrix solution.
    • 公开了一种用于从钛轴承固体中回收二氧化钛和其它有价金属的方法和系统。 该方法包括将固体在盐酸中浸出以产生包含不溶性固体的浸出液和包含二氧化钛和金属金属的浸出溶液,其中盐酸浓度保持在维持二氧化钛和金属金属溶解所需的值之上 在大气压下的浸出溶液中。 浸出液分离成浸出溶液和未溶解的固体。 浸出溶液中盐酸浓度的浓度降低,通过水解和沉淀来回收二氧化钛,产生富含二氧化钛的浆料。 在优选的实施方案中,用基质溶液回收HCl。
