Digging deeper: Mining methods explained | Anglo American
Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity.

The six main steps of iron ore processing
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.
