The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.

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.
