Process analytical technology for resource analytics – The role of reference materials
- Resource Analytics with the help of process analytical technology and the use of online methods is becoming increasingly important for mining and processing technologies and for the recovery of raw materials from secondary raw materials. Current online analytical methods like laser-induced breakdown spectroscopy (LIBS), X-ray fluorescence analysis (RFA), or Raman spectroscopy for the characterization of primary and secondary raw materials are increasingly being used in close association with the technologies for exploration and extraction, mechanical and metallurgical processing, as well as for recycling. Because of the complex matrices such methods are a considerable challenge at the same time. The use of reference materials, which are derived from appropriate matrices, can considerably shorten calibration and method development times. As an example, the development of an online process control method for recovery of phosphorus from sewage sludge ashes is discussed.

As an example, the development of an online process control method for recovery of phosphorus from sewage sludge ashes is discussed. A combination of LIBS and RFA was developed for the determination of element contents in sewage sludge ashes and their products coming from a thermo-chemical reprocessing step, which removes pollutants.…
