The expediency of processing iron-containing concentrate with low iron content, increased content of manganese and copper is considered in the article. To process such a concentrate, a metallization process is proposed to produce sponge iron with a reducing agent carbon. It was found that in solid-phase reduction at 1150 °C iron is reduced to a greater extent, as well as small particles
The mechanical properties obtained in austempered ductile iron castings are dependent on metallurgical process variables, including metal composition and heat-treatment conditions. The former determines also, to a large extent, the size of section which can be fully transformed. The effects of these metallurgical variables on both the structure and mechanical properties of austempered ductile
2021-5-1 This paper demonstrates the possible nondestructive analysis of iron artifacts’ metallurgical characteristics using neutron imaging. Ancient kingdoms of the Korean Peninsula used a direct smelting process for ore smelting and iron bloom production; however, the use of iron blooms was difficult because of their low strength and purity.

Jiuquan Iron and Steel Co has developed a new acid agglomeration process (pellet sintering process) to improve the composition of charge materials for blast furnace and the problems of using fine
The answer is the option (i, ii). Oxides reduction can be done by using carbon. Haematite (Iron ore ) and calamine contain oxygen, so they can be reduced by carbon. Sulphide ores cannot be reduced by carbon. Iron pyrite and sphalerite are sulphide ores of iron and zinc respectively.

Generally speaking, product structure and casting process (gating system, mold, gas generation and exhaust), composition of molten iron, metallurgical factors and dynamic factors of pouring process are the main aspects related to shrinkage cavity and porosity of ductile iron. In this paper, the melting control of molten iron and the influence

To develop a process that would ensure high metallurgical properties, we have analyzed the hematite dissociation reaction. It was found that the temperature and the content of slag-forming oxides influence this reaction. A sinter pot was used to carry out the research and determine metallurgical properties of partially dissociated pellets.
The defined oxidation ability of metallurgical slags based on the ion and molecule coexistence theory (IMCT), i.e., the comprehensive mass action concentration of iron oxides, has been verified through comparing the calculated and the reported activity of iron oxides in the selected Fe t O‐containing slag systems. To calculate the defined comprehensive mass action concentration of iron
