    Iron production by using the direct method has been promoted in order to produce iron effectively, low cost, and environmentally safe The method was optimal requirements with respect to the feed materials especially iron ore, coal as well as a binder In this study, the experiments were conducted on physical properties of iron ore briquette from Aceh (Indonesia) to analyze its suitability tomaterials of iron ore and coal are both important to affect the reduction behavior, in this study we focused on the effects of coal type The results are expected to obtain a criterion of coal selection and to be preliminary understanding on the thermalchemical behavior of the carbothermic reduction for ore/coal composite pellets packed in a tall bed 2 EXPERIMENTAL 21 Raw materials The03Effect of Volatile Matter Content of Coal on

  • Iron ore as a main dry cargo OpenSea

    The iron ore is the dry bulk cargo with the largest trading volume per year, above coal and grains Iron ore is found in nature in form of rocks, usually mixed with other elements and after it is processed by various industrial processes, it is sold to steel companies In general, there are not special subcategories of iron ore as it happens with the coal or grains Its main categorization isutes to the reduction of iron ore, so in that case the effect of coal type cannot be revealed accurately In the study of Zhang, the calculation method of coal consumption was not described 14) Four types of reducing agent were employed by S Weissberger and Y Zimmels3) for the direct reduction of Ramin oolitic iron ore, and significant differences of the iron contents in concentrates andEffect of Coal Type on the Reduction and Magnetic
