What technology is used in the IonicX Portable XRF Analyzer? Product FAQ

Answer

The IonicX Portable XRF Analyzer is an X-ray fluorescence spectrometer (https://www.thermofisher.com/us/en/home/industrial/spectroscopy-elemental-isotope-analysis/spectroscopy-elemental-isotope-analysis-learning-center/elemental-analysis-information/xrf-technology.html). XRF is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the elemental composition of a sample by measuring the fluorescence (or secondary) X-ray emitted from elements in a sample when they are excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic X-ray lines (“a fingerprint”) that is unique for that specific element, which is why XRF spectroscopy is an excellent technology for qualitative analysis of material composition.

When choosing an online slurry analysis system, what process control requirements should be considered? Product FAQ

Answer

The following process control elements should be considered in selecting the most suitable configuration for an online slurry analysis system:

- Elements to be analyzed. For example, analyzers utilizing the Prompt Gamma Neutron Activation Analysis (PGNAA) technique have a distinct advantage over analyzers using X-ray fluorescence by being able to measure light elements (those lower than calcium on the periodic table)
- Frequency of analysis (assay update time) as dictated by the process control strategy
- Residence time of upstream process
- Importance of stream in overall control strategy
- Confidence required in assay-based control decisions

What technical questions should be asked before deciding upon on an online slurry analysis system? Product FAQ

Answer

Before selecting an online slurry analysis system, consider if light elements will need to be measured and if the measurement technique is amenable, given the expected variation in mineralogical and particle size for the process. In addition, look at the streams to be measured and ask these questions:

- What is critical for control of process (usually includes Feed, Final Tail, and Concentrate)?
- Is there a need for understanding trends within the process (usually includes Rougher Concentrate and Cleaner Tails)?
- What are the elements to be measured in each stream?

Based on this information, the various trade-offs taking into account all factors between centralized and dedicated analyzers, Prompt Gamma Neutron Activation Analysis (PGNAA) and X-ray fluorescence (XRF), capital and maintenance cost etc., can be worked out and a recommendation made for the optimum system configuration for the particular plant

For example, in a nickel concentrator, it is essential to control the concentration of talc (or MgO) in the concentrate stream. To be able to control the concentration of talc in the concentrate, one requires measurement of Ni and talc in each of the feeds, rougher concentrate, and final concentrate streams so that the appropriate concentration gradients between these can be optimized and the ratio of Ni/talc can be maximized at each stage for minimum reagent usage. It may also be useful to measure Fe and S in the feed stream because this may give an indication of the nickel mineralogy entering the plant. In all other streams, it is only necessary to measure Ni because the information from these streams is used only for monitoring the recovery of Ni. Thus, PGNAAA would be required with multiplexing for the three main streams, and possibly a multi-stream analyzer (using XRF technology) for the other streams).
