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.

Mining crushing grinding costs
The purpose of this data-file is to tabulate typical cost estimates for crushing-grinding processes, which consume 1-2% of all the energy in the world and 20-50% of the energy in some mining processes. Our numbers are shown per ton of ore, so clearly lower ore grades translate into higher costs per unit of extracted material ().Energy economics.
