烧结过程中的FeO可以被CO还原生成CO2。（)

在RH过程中,[C]、[O]反应生成CO气体,由于降低了气相中CO的分压使[C]和[O]的反应向着生成CO2气体的方向进行。()

矿石中极易被CO还原的元素是（)。
A、Cu
B、P
C、Ti

热风烧结不但可以提高成品率，而且使其中的FeO含量降低。（)

向一定量的Fe、FeO、Fe2O3的混合物中，加入100mLl mol·L－1的盐酸，恰好使混合物完全溶解，放出2.24mL（标况)的气体。所得溶液中，加 入KSCN溶液无血红色出现，那么用足量的CO在高温下还原相同质量的此混合物，得到铁的质量为 （)

B、$7,900,000
C、$7,780,000
D、$12,220,000
