Iron tailings

Iron tailings is a kind of composite mineral material, which is the residual waste residue of iron ore after selecting iron concentrate, which is sand granular and often called "iron ore sand". In addition to a small amount of metal components, the main mineral components of iron tailings are gangue minerals such as quartz, pyroxene, feldspar, garnet, hornblende and their altered minerals. The key technical indicators such as particle gradation and thickness of iron tailings sand fluctuate greatly, and its shape is similar to that of machine-made sand particles, with rough and irregular shape, many edges and corners, many microcracks inside the particles, large porosity and small roundness. Iron tailings in more than 80% of the material is non-metallic minerals, and building materials component ten

The key technical indicators such as particle gradation and thickness of iron tailings sand fluctuate greatly, and its shape is similar to that of machine-made sand particles, with rough and irregular shape, many edges and corners, many microcracks inside the particles, large porosity and small roundness.

More than 80% of the iron tailings are non-metallic minerals, which are very similar to the components of building materials, which provides a prerequisite for the widespread use of iron tailings as raw materials in the building materials industry. The research on the use of iron tailings as raw materials for building materials in China began in the 1980 s.

Iron tailings are widely used in paving materials, yellow sand substitutes, cement aggregates, production of cement, wall materials, goaf filling materials, soil improvers and trace element fertilizers.
