Iron Ore Reduction an overview ScienceDirect Topics

Hydrogen can serve as a reducing agent and the most prominent application appears to to be iron ore reduction. A variety of direct reduction of iron ores without coke has been carefully studied for a long time. These use hydrogen, carbon-monoxide and carbon in a combination. The reason for the development is due to the following:

Recovery of iron from hazardous tailings using fluidized

2020-02-01· Li et al. presented a technique for recycling iron ore tailings via the coal-based magnetization roasting process followed by magnetic separation (MRMS). Using a similar method, rare-earth tailings containing 13.06% Fe could be transformed to an iron ore concentrate assaying 45.00–49.00% Fe with a recovery of 65.00–77.50% [ 10 ].
