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.

Autogenous Grinding Process | SpringerLink

In wet autogenous grinding, the grinding process is easy to adjust and control and free of environmental pollution. It is widely used by mineral processing plants. If the 30–80 mm pebble generated during autogenous grinding is used as the medium to crush the ore, the process is called pebble grinding.

Beneficiation

The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. The second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry. The hydrocyclone operates between each grinding operation to classify the type of particles: fine or coarse (Long et al., 1998).
