Fluidized bed chloride method for obtaining metal oxide concentrate, expecially titanium dioxide ERE

描述了一种从包含金属和铁的矿石获取金属氧化物浓缩物的方法，其中在流化床反应器中，在碳和非必要地进一步添加剂的存在下，在大于900℃的温度下将矿石曝露于氯气的作用。在此反应在流化床反应器中批次进料进行，向流化床反应器中提供作为流化气体的含氧气体和氯气。与用于除去作为氯化物的铁所需反应的碳量相比碳过量大约5wt％以上。排出富含金属氧化物的产物。此方法以简单而经济的方式提供有价值的工序产物。 Disclosed is a method for obtaining metal oxide concentrate from an ore containing metal and iron. The ore is subjected to the effects of chlorine in a fluidized bed reactor in the presence of carbon and optionally other additives at a temperature of over 900 DEG C. The reaction is carried out in batches in the fluidized bed reactor and a gas containing oxygen, and chlorine are fed to the fluidized bed reactor as a fluidizing gas. More than 5 wt. % excess carbon is present, in relation to the required amount for the reaction, in order to remove the iron as chloride. A product enriched with metal oxide is removed. A valuable reaction product can thus be obtained by the inventive method in a simple, economical way.
