Around 8-10 million tons of slimes are discarded during the washing process in India, containing about 48-60% of Fe every year (Prakash et al., 2000), almost 15% of the total ore mined.In iron ore-based steelmaking, steel is produced from iron ore. The first step is ironmaking and the main route for iron production is the BF process; 95% of the world’s iron production in 2012Flow sheet over the steelmaking processes. Steel can be

Direct Iron Ore Smelting Process for Ironmaking IspatGuru
Fig 1 Flow sheet of 6000 tons per day DIOS plant. Process description. DIOS process has the characteristics of (i) iron ore and coal fines can be directly used, (ii) there is no requirement of coke and hence there is no restriction on the kind of coal used in the process, (iii) process can be stopped and restarted easily and hence good flexibility From the table 1 and size-analysis data, it can be found that +0.212 mm fraction contains more than 80% of total iron and 85% of silica and magnesia All impurities are concentrated in the coarserPROOF UNCORRECTED ResearchGate

The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate that use electrical energy to reduce iron ore. In electrolysis, iron ore is dissolved in a solvent of silicon dioxide and calcium oxide at 1,600°C, and an electric current passed through it. Negatively-charged oxygen ions migrate to the positively charged anode, and the oxygen bubbles off. Positively-charged iron ions migrate to the negatively-Fact sheet Electrolysis in ironmaking Steel
