PANalytical has added a new segment to the mining applications section of its website called Minerals Analysis. In this section it has included, and will continue to add, content that highlights minerals that have spectrally active features in the near infrared (NIR), making them ideally suited for the rapid, precise mineral analysis of the TerraSpec 4 mineral analyser.
How can mining become more environmentally sustainable. The continued discoveries of new oil, coal, and mineral reserves, improved recycling, including froth floatation for processing certain metal sulphide ores, the, generates electricity while transporting bauxite ore downhill from the mine to the.
Known formally as bauxite residue, red mud is the noxious by-product of the Bayer process for extracting aluminum from bauxite ore. Aluminum mining leaves behind a staggering 120 million metric tons per year of the salty, highly alkaline, heavy-metal-laden material, according to the International Aluminium Institute, a London-based trade organization.

Bauxite residue is the waste generated during alumina production by Bayer's process. The amount of bauxite residue (40–50 wt%) generated depends on the quality of bauxite ore used for the processing. High alkalinity and high caustic content in bauxite residue causes environmental risk for fertile soil and ground water contamination.

Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).
This enables accurate ore sorting and stabile ore output to maximize the efficiency of the ore blending and the beneficiation process. They can be employed for continuous, non-contact monitoring of elemental and mineralogical composition in a large range of mining applications such as coal, copper, iron, bauxite or nickel.
