Sintered Ore - Philippine Sinter Corporation

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 ...

The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.
