Proceedings, Iron Ore 2013, pp 485-486 (AUSIMM: Melbourne) However, if a producer fails to acknowledge the textural composition of fine goethitic ore during sintering, they’re unable to capitalise on this additional efficiency. If the goethite types are ...Emission Optimized Sintering (EOS ) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:

This knowledge can be used to optimise processes for cost savings and productivity benefits.consists of a cellular mass of ore bonded in a slag matrix. The sinter mix, besides the ore fines, usually contains other materials like flue dust, return fines, limestone and/or dolomite etc., in order to control the properties of the product as well as to utilize industrial waste. Return sinter fines having lower fusion temperature than the raw mix serve as seeds for initiation of the sintering process.
