Method for comprehensively treating vanadium titano-magnetite through fluidized hydrogen reduction-electric furnace melt separation
The invention discloses a method for comprehensively treating vanadium titano-magnetite through fluidized hydrogen reduction-electric furnace melt separation, and particularly relates to the technical field of vanadium titano-magnetite treatment. Step 2, melt separation; 3, vanadium blowing; step 4, sorting and separating the titanium concentrate; and step 5, acid leaching. The method aims at overcoming the obvious defects existing in the traditional blast furnace-converter method for treating the vanadium titano-magnetite. And the comprehensive utilization recovery rate of the vanadium titano-magnetite can be improved. According to the method, fine-fraction fine ore can be directly treated, the reduction efficiency is high, heat exchange is good, environmental pollution is small, and valuable elements such as iron, vanadium and titanium in main components can be effectively separated and recycled.
本发明公开了一种流态化氢还原‑电炉熔分综合处理钒钛磁铁矿的方法，具体涉及钒钛磁铁矿处理技术领域，具体包括如下步骤：步骤一，还原；步骤二，熔分；步骤三，吹钒；步骤四，钛精矿的选别分离；步骤五，酸浸。本发明针对传统“高炉‑转炉法”处理钒钛磁铁矿存在的明显弊端。可以提高钒钛磁铁矿的综合利用回收率。本发明能够直接处理细粒级粉矿、还原效率高、热交换好、环境污染小、并且能够有效的分离与回收主要成分中的铁、钒、钛等有价元素。
