DESCRIPTION

PD ISO/TR 18230:2015


This standard PD ISO/TR 18230:2015 Iron ores. Determination of loss on ignition. Non-oxidised ores is classified in these ICS categories:
  • 73.060.10 Iron ores

This Technical Report describes a gravimetric method for the determination of the loss in mass of nonoxidized iron ores, when ignited at 1000 °C.

This method is applicable to a concentration range of a mass fraction of −3,0 % to 7,0 % loss on ignition in natural iron ores, iron ore concentrates and agglomerates, and sinters.

The method is not applicable to the following:

  1. processed ores containing metallic iron (direct reduced iron);

  2. natural or processed ores in which the sulfur content is higher than a mass fraction of 0,2 %;

  3. internationally traded ores with combined water greater than 2,5 %.

NOTE 1 Loss on ignition can be used as an estimate of combined water.

NOTE 2 This method is intended for in-house use and is not intended for referee purposes.
