The six main steps of iron ore processing

When iron ore is extracted from a mine, it must undergo several processing stages. 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.

Everything you need to know about screening

Crushed materials are often angular and require different screening. The presence of fines can increase the feed speed of industrial screening. Moisture forces the particles to stick together, which limits the efficiency of the process. The difference in size between particles is a key factor. Screening systems: types of screening

Beneficiation

A primary or jaw crusher is located at the mine site and reduces the particle diameter of the ores into <6 in. 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.
