提钪萃余液制取铁红的研究
Preparation of Iron Red Using Extraction Raffinate of Scandium
【摘要】 针对赤泥提取钪后的萃余液中含有的大量FeCl3,采用氨水中和使铁、铝沉淀,再以碱溶解,使 Fe、Al分离开来,最后焙烧含铁沉淀物制得氧化铁红颜料。
【Abstract】 There are plentifulFe3+and Al3+in raffinate from extraction of scandium by solvent extraction. Fe3+ and Al3+ can be precipitated by adjusting pH using ammonia.The precipitates are again dissolved using NaOH solution,Fe can be separated from Al. Iron oxide red can be preparated by roasting the precipitate containing Fe.
