    Sedimentary ore deposits include banded iron formations, and gold, platinum, zinc, tin, and even diamond-containing ores that formed in sedimentary environments. Lastly, ores can form as a resultOre Beneficiation an overview ScienceDirect Topics,Crushing and screening is typically the first step of iron ore beneficiation processes. 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.
