In the absence of laboratory analysis, Sauder suggests the following simple method of estimating iron content of a sample : A measured weight of ore is crushed and placed in a small jar, the fill with muriatic
Development of a method for determination of metallic iron content
The growing use of metallic iron in metallurgy and industrial chemical appliions requires a fast, easy and cheap method for the determination of metallic associated resources (i.e. iron ore, scrap, slag etc.). Generally these methods are but they have found different metallic iron result in same sample (e.g. HBI or DRI).
