High alloy iron. The properties of both white and gray cast irons can be enhanced by the inclusion of alloying elements such as nickel (Ni), chromium (Cr), and molybdenum (Mo). For example, Ni Hard, a white iron containing 4 to 5 percent nickel and up to 1.5 percent chromium, is used to make metalworking rolls.

Iron processing. Mostly it appears in iron carbon alloys such as steels, which contain between 0.003 and about 2 percent carbon (the majority lying in the range of 0.01 to 1.2 percent), and cast irons with 2 to 4 percent carbon. At the carbon contents typical of steels, iron carbide
Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
