Direct use of manganese fines in the submerged arc furnace (SAF) will lead to the low permeability of the charge, essentially increase the consumption of coke and electric energy. In order to make better use of manganese fines as well as to save energy and cost in the industry, the sintering process of manganese ore is particularly important.
Coke breeze is often preferred as the carbon source due to its lower cost compared with metallurgical coke. Manganese sinter operations have been well described 12,[37][38] [39] in previous ...
After a sharp jump of 40% in 2021, global finished steel cash costs rose even further in 2022, primarily driven by surging raw material and energy prices. Iron ore prices fell 22% for the year while hard-coking coal prices exploded by 97%. This price rise increased global average cash costs for finished steel by 15% in 2022 to reach US$736/t.
has built more than 400 iron ore sinter plants worldwide. This process, primarily used for iron ores, can also be used for sintering manganese and nickel ore fines. Our energy-optimized version of the sintering (EOS) process reduces off-gas volumes and the emission of hazardous pollutants, while simultaneously reducing fuel consumption.
The bigger machines have less heat losses and prove energy efficient. The world's largest sinter machine provides 600 m 2 bed area while the largest machine in India at JSW has 496 m 2 bed area. The average bed area of the sinter machine in India is 153 m 2.The sinter cooler technology is available with 11 units in India out of a total 34 …
There are currently two manganese ore sinter plants in South Africa. Both are situated next to manganese mines. The market for manganese sinter is both local and for export.

Sinter quality begins with the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. Sintering process fluctuations, inhomogeneous mixtures, and other parameters affect productivity, physical and metallurgical quality, and raw material consumption and costs.

Additional information on the estimated GHG emissions from the Iron and Steel sector is provided in Appendix D. The following paragraphs provide brief descriptions of Iron and Steel processes. Lists of plants and locations can be found in Appendix B.
required to produce 0.9 Mg (1 ton) of product sinter. 12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel.
The cost proportion of electric power accounts for 21.40% of total production cost in the typical RKEF plants in China (Fig. 1.17). This proportion will be higher in Indonesia, due to the low cost of laterite ores.
