Sintered Ore

Sintered Iron Ore/ Sintered Ore (SO) is the result of the sintering process. The product is made of ferrous and calcium which can be produced from fine iron ore and limestone thru a sintering machine. This mixture is then burned in a sinter machine to form hard but permeable lumps called sintered iron ore. The sintered iron ore is then fed to a ...
