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.
