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.
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...

Grinding ball mills are rotating equipments commonly present in iron ore mining plants, which use steel balls to reduce the ore particle size and prepare the ore pulp for subsequent concentration process. The ball mill is basically a large cylinder consisting of a shell, two slide rings which are supported on sliding bearing (one fixed …
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
