| titleOfInvention | A method of cementite is prepared using low-grade complex iron ore |
| abstract | The present invention discloses a kind of method using low-grade complex iron ore preparation cementite, comprising: is uniformly mixed low-grade complex iron ore with binder, and pelletizing material is made；The pelletizing material is made into green-ball and is roasted after drying, carburizing pelletizing is obtained；By the carburizing pelletizing in CO+CO 2 +H 2 Or CH 4 +H 2 Carburizing, cooling in inert atmosphere is carried out in gas, obtains pelletizing after carburizing；Pelletizing after the carburizing is subjected to wet ball-milling, wet magnetic separation is carried out after ball milling, is dried to obtain cementite.Method provided by the invention prepares cementite efficient quick, low in cost, energy conservation and environmental protection. |
