How Are Granites Seperated From Ore Waste Rock

User Guidelines for Waste and Byproduct Materials in

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.
