Phosphorus impurity cannot be removed by this process

Vedclass · Answer

(B) The basic open-hearth process is specifically designed to remove phosphorus impurities from pig iron by using a basic lining (such as $CaO$ or $MgO$) and adding limestone $(CaCO_3)$ to the charge. Therefore,the statement that 'Phosphorus impurity cannot be removed by this process' is incorrect,as this process is highly effective at removing phosphorus. Other statements like adding limestone,controlling carbon content,and utilizing iron scrap are correct features of the basic open-hearth process.
