The six main steps of iron ore processing
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Iron Ore: From Mining to Processing to Dust Control
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
