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.

Extraction of Iron from Copper-Plant Slag
Chemical anal-ysis shows that most of the iron is concentrated in par-ticles of 160–2000 μm. The copper content in the frac-tions from 80–125 to more than 2000 μm varies from 0.5 to 0.3%1. In the <80 m fraction, ~1.5% copper is μ present. Accordingly, this fraction may be used as a recycled product.
