Nearly all commerically mined potash deposits originates from evaporit deposits and contain potassium chloride (KCl), sodium chloride (NaCl) and other salt and clay minerals. Salts have a good signature in the NIR spectra and therefore potash is very well measurable with SpectraFlow. The analyzer can be used all over the production process, directly after the mine, for the final product or for the waste material.

Also Apatite as the main phosphate containing mineral has a very good signature in the NIR spectra, therefore also Phosphate ore can be measured very well with SpectraFlow all over the production process.
