Treatment of chlorination residue |
摘要 |
<p>Alkali and alkaline earth metal chlorides contained in a residue of a chlorination process of a feed material of bauxite or clay associated with coal are removed by the addition of sulfuric acid which causes their conversion to their sulfate form and the simultaneous production of hydrochloric acid. The hydrochloric acid can be recycled to the chlorination process. The hydrochloric acid may be utilized, for example, as a binder of the feed material, to prechloridize the feed material or as a portion of the leach solution when the chlorination process is a hydrochloric acid leach.</p> |
