“…Beach placer is highly weathered, with a large Fe 2 O 3 /FeO ratio and high Ti content, while Ti-bearing material often exists in the form of ilmenite (FeTiO 3 ), ulvospinel (Fe 2 TiO 4 ), and titanium magnetite (Fe 3−x Ti x O 4 ) [5,6]. Due to the close symbiosis of Fe and Ti elements from beach placer, the methods of separating them efficiently have become a hot issue in current research [7]. Until now, numerous studies were conducted for this kind of complex minerals, such as the pre-reduction-electric furnace method [8,9], sodium vanadium extraction-prereduction-electric furnace method [10,11], and reduction-grinding method [12,13].…”
