Low Heavy Metal Calcined Magnesite for feed and fertilizer
Calcined magnesite is a cost effective source of chemical grade magnesium oxide – used as an alkali for acid neutralisation in the process and subsequent effluent treatment. A range of purities are available along with a choice of particle size. 90% magnesium oxide is the most cost effective grade, whereas 94% magnesium oxide introduces the lowest unwanted non reactives. Fine particle sizes are more reactive than coarse powder but can be found less easy to handle during processing. Caustic(Light) burned magnesium oxide is a reactive grade of magnesium oxide that has been calcined at temperatures ranging from 700ºC – 1000ºC.
