Moisture of Mineral Ore
Moisture titration using Karl Fischer reagent is popularly practiced water determination worldwide as the most reliable method. The procedure is adopted in many official standards as test method specified in ISO, ASTM, DIN, BS, and JIS.
Mineral ores are hard to dissolve in KF solvent, and therefore, the indirect method using an oven to evaporate moisture in samples is generally practiced. The test sample is first heated in the oven, and the evaporated moisture is transferred to measuring cell by carrier gas where moisture titration is performed according to JIS M 8211-1995.
