liquefaction risks iron ore sinter feed maritime

Sinter feed indicates that the cargo is too fine-grained for direct use in a blast furnace and therefore will undergo a process of agglomeration (sintering) into larger particles at destination before smelting. Thus, it is descriptive of the use of the product rather than its properties or production method.

chapter11 fundamentals of iron ore sintering

Iron ore sintering is undertaken at steelworks to produce coarse and competent feed for the iron blast furnace from iron ore fines and secondary iron oxide sources. In the sintering process, a blend of iron oxide fines ( 6 mm) is mixed and agglomerated with the addition of fluxes, return sinter and coke breeze.
