Quantitative Determination of Metallic Iron Content in ...

2013-12-24  The accurate determination of metallic iron content and total iron content is vital before and after processing of the received by-products. This is critical for the mass balance, results interpretation, and quality control. There are several well-defined methods for the determination of the total iron content in iron ores and related materials. These methods include silver reduction-dichromate titration (ASTM E 1081-95a), hydrogen sulfide reduction and dichromate titration (ASTM E 246-95), and dichromate titrimetry (ASTM E 1028-98). However, no ASTM standard test method of metallic iron content for iron or steel slags and related materials has been defined. When the slag sample is sent to the different labs, the different and even contradicted results are given. It is very difficult to make a decision how to deal with the steel-making by-products without an accurate metallic iron content

Iron Fines that may Contain DRI (C) Fines – Officer of the ...

2013-2-6  The iron in a cargo of iron ore is chemically bound with other elements and therefore contains no metallic (or free) iron. If the cargo contains any metallic iron (Feº), then it must be a DRI derivative; DRI (A) and DRI (B) cargoes typically contain about 85% metallic iron, whereas in blends containing DRI (C) it can be as low as 1% or 2%.
