 " Methods of reducing scale in the Bayer process have been disclosed in WO 2004/009606.

   It is anticipated that the disclosed process may be employed even after a small amount of scale

   has already been built up on the surfaces of the equipment employed eg heat exchangers. This would

   also prevent any adverse effect such as corrosion or pitting which might affect clean metal surfaces

   that may be exposed through use of referenced scale inhibitors.

    In the unlikely event that these corrosion processes present a problem, the scale inhibitors disclosed

   in the cited patent publication may also be used in conjunction with a know corrosion inhibitor"
