Comprehensive Utilization Of Iron And Phosphorus From

An innovative process of coal based reduction followed by magnetic separation and dephosphorization was developed to simultaneously recover iron and phosphorus from one typical high phosphorus refractory iron ore. The experimental results showed that the iron minerals in iron ore were reduced to metallic iron during the coal based reduction and the phosphorus was enriched in the metallic iron.

Reaction Behavior Of Phosphorus In Coal

Coal based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction.

Removal Of Phosphorus From High Phosphorus Iron Ores

In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.
