Abstract
Abstract. We have many iron-bearing materials in earth-crust, which contain considerable amount of Iron. But only a few of them are utilized as the industrial raw material at present and the rest of them-iron-sand, titaniferous iron-ore, iron-pyrite, purple-ore etc.-are not used to the same purpose, in spite of their high contents of iron, because of their refining process is not yet found.
The author, therefore, attempted to get pig-iron and steel from these disused Ores. the experiments were carried in 3-ton basic Electric-furnace by adding several kinds of reducing agents in varying quantities under special attentions to the charging method and was able to find out an easy refining method of them.
The author got various kinds of iron by this method and concluded that it is most economical to produce the pearlitic cast-iron or the Steel directly, in the case of utilizing these ores.
