how can determine percentage feo in mill scale

Total generation of mill scale at JSWSL isaround 150 t/dayand contains60–70%FeO and 30–35%Fe 2 O 3.To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.

    Iron mill scale prices are currently being traded depending on the quality of the load in the range of 170 to 250,000 tomans per tonne. We determine iron mill scale prices byexamining several cargo features. The first is the percentage of iron purity in the iron mill scale, the second is the ratio of oxide shell fines and grains compared to the amount of pigment shell coins.
