2019.11.4 Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

Dry and Wet Screening in Mining: What are the Differences?
2018.2.14 Two deck models augment the process while keeping the cost of the equipment range manageable. Meanwhile, the wet “slurry” produced by the sprinkler nozzles necessitates a dewatering stage. Having said that, there comes a point when dry screening is no longer viable. For example, powdered coal requires a wet screening stage.
