Screening: The first one is screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage.; Crushing and stockpiling: This step involves breaking up the iron ore to obtain an F80 grind size before it can be ground. Once the ore is crushed, it is diverted to a stockpile and then fed into the mill; Grinding: The primary …

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.
