| titleOfInvention | The method that microwave reinforced direct-reduction processing ilmenite produces reduced iron powder and rich-titanium material |
| abstract | The invention discloses a kind of microwave reinforced methods direct-reduction processing ilmenite and produce reduced iron powder and rich-titanium material, belong to the technology field of mineral green metallurgical.Using sodium agent sodium carbonate to ilmenite by pretreatment ball mill mixing; under inert gas protection; it can be realized quick ironmaking using microwave heating to certain temperature and held for some time; and obtained product is by carbonating ball milling hydrolysis; the isolated reduced iron powder of magnetic separation and initial rich-titanium material; initial rich-titanium material passes through dilute hydrochloric acid acidleach, obtains rich-titanium material after being not more than 3h processing not higher than 973K heat preservation.The advantage of the invention is that entire reaction is at a lower temperature, reaction temperature is controlled in 1073K-1173K, quickly reduction can be realized within 10-20min, obtained reduced iron powder is directly used in electro-smelting into metallic iron, and obtained rich-titanium material can be directly used for the raw material of chloridising production. |
