Mar 06, 2012· Standards are prepared using a phosphate standard solution of 3 mg/L as phosphate (PO4). This is equivalent to a concentration of 1 mg/L as Phosphorus (P). All references to concentrations and results from this point on in this procedure will be expressed as mg/L as P, since this is the convention for reporting results.
Ultra-fine grinding is mandatory in some industries (e.g., mica produced for the paint industry must be gorund to below 10 microns). Current ultra-fine grinding by vertical stirred mills has very high energy requirements (Gao et al., 1995; Orumwense and Forssberg, 1992).
