Study of the Process of Metallization of Ore-Coal Pellets During Roasting in a Layer.

A study is made of the process of metallization of ore-coal pellets with the involvement of the liquid phase. It is established that the degree of metallization of the pellets depends both on the carbon content in the pellets and on their basicity. The presence of oxidizers (CO//2 and O//2) in the gaseous phase significantly reduces the degree of metallization. The process of metallization of a layer of ore-coal pellets may be considerably intensified by the addition of magnesium oxide, recovered metallized pellets, and manganese concentrate.
