Nowadays, one may consider the processing of minerals with contents above 35 iron to obtain concentrates with up to 68 iron. Currently the process is carried out dry and partially wet. Dry processing normally goes from the mining extraction of the ore in the mine up to the sieving and crushing operations. When processing natural fines from ores, the wet stage is started after crushing with the addition of large quantities of water. The wet stage begins at grinding.

The most common process of concentration, capable of processing large quantities of ore, is flotation, carried out in mechanical cells or flotation columns. Flotation requires a desliming stage, which consists of the extraction of the natural ultrafines or these plus those generated in the grinding process. This is done on a wet basis and requires the movement of large volumes of water, as well as the placement of the sandy tailings and the slimes from the process in dams.

Taconite is mined primarily in the U.S., in the Mesabi Iron Range in Minnesota and the Marquette Iron Range in Michigan. Recovery of the iron requires fine grinding and concentration of iron-bearing phases, which in turn are formed into pellets suitable for blast furnaces. As high-grade deposits of iron ore have become depleted, taconite.
