I'm sorry but I don't know how to reduce the P₂O₅ in phosphogypsum. It is inherent in the material and therefore I cannot envisage a means to do that which would economic for its subsequent use in the cement industry.

I would be very interested to hear any pointers you might have about where how best to get started on using microscopy as a further tool for examining clinker ? Where training might be obtained ? Anyone you might recommend thatI could contact and who could possibly come on site and provide this training ?

An article describing the work we have been doing in Slovakia will appear in the February 2003 issue of International Cement Review. In part this describes how microscopy is used in combination with pattern recognition in hour-to-hour control of the real mineralogy of clinker.
