Developments in chemical separation of iron ore ...

2015-1-1  Chemical separation of impurity elements, such as silicon, aluminum, and sulfur, from iron ores often occurs in the processing to remove phosphorus from the ore. The treatments may include caustic or acid leaching of the ore, with or without a heating treatment, and magnetic separations between treatment steps.

Red ochre decorations in Spanish Neolithic ceramics: a ...

2007-2-12  Some Neolithic ceramics from south-eastern Spain have red to brown external decorations called ‘‘almagras’’ (red ochre). The pigment layeris essentially composed of a mixture of clay and iron oxides: haematite (red) and maghemite (brown). It is suggested that maghemite was formedduring the firing process of ceramic in a reducing atmosphere. Several laboratory tests have been carried out to

2017-4-20  Moreover, the degree of fineness to which the ore must be crushed determines the process of separation to be employed. An ore which must be crushed to 1/8 in., 1/16 in., or lower will require the wet method of separation, while for larger sizes the dry method can be most profitably employed.

What Is Iron Ore Beneficiation? (with pictures)

Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
