Waste rock can be processed to a desired gradation by crushing and sizing, like any other source of aggregate. The hardness of the waste rock is determined by the rock type. For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense.

The ore is then removed, crushed and refined using various enrichment methods that extract the desired metal and/or mineral. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio ...

In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock. Secondary crushing and screening can result in further classification and grading of iron ore.

The mining industry is an important industry in South Africa. It involves a number of industries working together. Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
