This study analysed the manufacture of iron sponges using Cipatujah iron sand, as raw material for the manufacture of iron sponges, with the results obtained in the form of iron sponges with the highest levels of Fe ≥60.44%. This can be used for the purposes of raw materials for steel making PT. Krakatau Steel (PT. KS), because so far PT.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel — 98% of the mined iron ore is used to make steel. [2]
The large iron sponge is then softly hammered into a solid bar, driving out slag in the process. This iron bar (wrought iron) can then be used to make tools and …

CV Asri Keramik conducted a demonstration of producing sponge iron from iron ore using a tunnel kiln. The demo involved crushing iron ore, mixing it with …
202411· It is the non-coke ironmaking process in which a gaseous, liquid, or solid reductant is used to reduce the iron ore into metallic iron in a temperature less than the ore softening temperature. The product is direct reduction iron which is an ideal raw material for producing high-quality steel and clean steel. Direct reduction iron contains large number of fine …

The document discusses the inputs and process for manufacturing sponge iron in a rotary kiln. It describes the chemical and physical composition of iron ore, …
2025222· Direct reduced iron (DRI) process: Natural gas or hydrogen reduces ore at low-to-medium temperatures to produce sponge iron. After ironmaking, the product still contains impurities and needs further refining to produce steel.
Ideally, the iron sands that are found in Aceh are very likely to have the added value when it is processed into pig iron and/or steel and its alloys before it is being exported. The process that can be done includes the beneficiation process or refining process, pelletizing that is ready to be used as raw materials in the manufacture of sponge iron or pig iron, the reduction process that
The properties of sponge iron produced from iron sand and its alloys from the Manggamat Simpang Dua region in South Aceh are discussed in this research. Sponge iron is produced in pellet form by combining 75 percent iron sand (Fe), 20 percent carbon (C), and 5 percent bentonite adhesive. Pellet manufacturing consists of five press variants, namely 50, 60, 70, 80, …
