Environmental impact of iron ore mining Wikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

Iron ore Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and

How Cement Is Made

The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller. The crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln.

Aluminium Geoscience Australia

Bauxite ore contains sufficiently high levels of aluminium oxides and suitably low levels of iron oxide (Fe 2 O 3) and silica (SiO 2) to be economically mineable. The amount of reactive silica is particularly important as this form of silica consumes the caustic soda needed to make alumina, thus low reactive silica is desirable.
