Online Real Time Elemental Analysis of Minerals and Raw Materials Through PFTNA Technique

With its high penetrating power, neutron activation is particularly well suited for online real-time elemental measurement. Unlike the conventional surface techniques viz. NIR phase analysis, LIBS laser micro-spot sampling or the hazardous radioactive isotopic sources, the D-T PFTNA based CNA (Controlled Neutron Activation) online analyzer—uses an electrical neutron source that can be switched ON and OFF any time. The CNA analyzer comprises a measuring chamber, with attached electrical box which uses digital signal processing technology and an operator interface. The CNA's measuring chamber, equipped with a robust BGO detector to detect gamma is installed around the conveyor belt and analyses the composition of material moving on it. Interfaced with a high-performance automatic system, the CNA not only makes it possible to measure and control the chemical composition of the raw materials but also adapt the manufacturing process. The CNA is widely used to control and optimize various manufacturing processes viz. in thermal power plants, cement manufacturing, mining & metals industry, ore-sorting, battery recycling and waste treatment plants.
