​ With new smart, easy and affordable XRF elemental analysis With extensive mining across the world, many mining companies are challenged with decreasing ore grades. “Geologists need not only reliable but frequent monitoring of the elemental composition of ores; so that they can make snap decisions to accurately predict and optimize recovery rates. This in turn making the extraction and separation of base metals - whether nickel, copper, zinc, a profitable process,” shares Dr Uwe Konig, global mining manager and geologist at Malvern Panalytical. Increase your process efficiency and recovery rate That is exactly why Malvern Panalytical offers comprehensive suite of material characterization tools, a safe, quick, and non-destructive method of elemental analysis known as X-ray fluorescence spectroscopy (XRF). XRF and in particular Malvern Panalytical’s Epsilon range of benchtop spectrometers are widely used by global to small and medium-sized mining companies across the world. Delivering reliable high throughput analysis, so you can be confident to make good decisions Malvern Panalytical’s R&D team has designed a revolutionary model, the Epsilon 4. We are proud that Epsilon 4 combines high analytical performance with low running costs. One of our customers, Ms. Monica Velasco of Berong Nickel Corporation shared, “The Epsilon4 is easy to use. It consistently delivers results according to set standards and is reproducible across different analysis methods. Initial cost is justifiable for the quality of the product. “  “The Epsilon 4 is easy to use. It consistently delivers results according to set standards and is reproducible across different analysis methods. Initial cost is justifiable for the quality of the product,“ says Ms Monica Velasco of Berong Nickel Corporation   Notice the significant improvements in sensitivity with the Epsilon 4 spectrum (yellow) compared to our earlier model the Epsilon 3 (blue spectrum) Fast and sensitive Fast measurements are achieved by using latest silicon drift detector technology that produces significantly higher intensities. Unique detector electronics enable a linear count rate capacity to over 1,500,000 cps (at 50% dead time) and a count rate independent resolution typically better than 135 eV for better separation of analytical lines in the spectrum. This allows the Epsilon 4 spectrometer to run at full power, resulting in higher intensities and therefore, giving better data quality, better limits of detection, lesser interference from overlapping elements and a much higher sample throughput compared to traditional EDXRF benchtop instruments. (See comparison with earlier model in Figure 1). Case study: accurate & repeatable measurements of nickel in as fast as 5minutes 25 secondary nickel ore standards containing Ni, Co, Mg, Mn, Zn, Al, Cr, Ca and Si were used to set up the calibration. All elements were measured in air medium.  On the left, note that the calibration plots demonstrate good correlation between the given concentrations and the measured intensities. On the right, notice the low standard deviations and high repeatability (Repeatability data missing) achieved. Combining the latest excitation & detection technologies and smart design, this data demonstrates how the analytical performance of Epsilon 4 approaches that of more powerful and floor-standing spectrometers.   High throughput analysis with unattended operations of Epsilon 4 The combination of a 10-position removable sample changer with spinner enables the automatic processing of sample batches without the need for operator attention. Continuous rotation of the sample during measurement minimizes any errors caused by non-homogeneity or surface irregularities within individual samples and provides more accurate results. Automatic transfer of data to a central location gives you access to the latest results. Did you know that you can even link the Epsilon 4 to an automation arm for continuous sample loading? Reduce expensive running costs with smart Epsilon 4 technology Little or no expensive sample preparation unlike other traditional elemental methods like ICP or AAS which require long durations of samples digested in acid. Reduce overheads without comprising on performance. The high performance of Epsilon 4 enables many applications to be operated in air atmosphere, without longer overhead time and costs involved for helium or maintenance of vacuum system. Even when measuring in air, Epsilon 4’s smart built-in sensors compensate for temperature or pressure variations. Hence ensuring excellent results whatever the weather. Save on calibration maintenance thanks to our new low-drift X-ray tube and automatic drift correction. Especially for high throughput environments, this ensures no downtime for calibration maintenance. You can be confident of your results always.

​ Philippine minerals have a wide range of ores from nickel laterite, copper ore, iron ore, chromite ore, limestone and more. Thus, when daily operations require elemental analysis of a wide range of inorganic/geological samples, it is often cumbersome, or not possible to setup and maintain a large number of dedicated calibrations to handle such range.  In these cases, a widely applicable, but accurate solution is highly desirable. In this application note we demonstrate Malvern Panalytical’s unique solution WROXI in combination with Epsilon 4 and Leneo sample preparation, is capable to handle a wide range of sample types. This is the value-added offerings by Malvern Panalytical to enhance precision elemental analysis, by way of in-house affordable traceability guaranteed CRMs. WROXI solution The WROXI BASE application module comprises 15 synthetic multi-elements standards, containing in total 11 different inorganic oxides. Made from traceable compounds WROXI is a primary analytical solution. The standards are delivered as powders to be prepared as fused beads on-site, using the customer’s flux, dilution ratios and methodology. Each set of WROXI standards is supplied with 15 bottles containing 10 g of powdered standards each, packed under nitrogen, in air-tight plastic bottles. Each set is supplied with drift monitors to maintain the application.  WROXI offers good calibration especially when doing shipment of ores and exploration thus following tolerance and penalty elements. It eliminates the use of different calibration in every ores and provides good accuracy and repeatability. Table 1. Concentration ranges of the 11 compounds in WROXI standards. Instrumentation A Claisse LeNEO automatic fusion instrument was used to make all the fused glass beads. LeNEO Requiring only an electrical connection and fume exhaust, the LeNEO can prepare glass disks for XRF analysis with high reproducibility. In addition to being easy to use, his fully automatic instrument guarantees safety for the operator as well as superior analytical performance in the laboratory.  Its muffle furnace and excellent insulation properties ensure uniform heating conditions providing excellent repeatability and reproducibility.  40 mm fused beads were produced by mixing 0.9 g of sample material and 9 g of flux (66 % lithium tetraborate / 34 % lithium metaborate). WROXI standards used to set up the calibration were prepared in duplicate. Measurements were performed using a Malvern Panalytical Epsilon 4 EDXRF spectrometer, equipped with a 15W, 50 kV silver anode X-ray tube, a high-resolution SDD30 silicon drift detector, 6 beam filters, a helium purge facility, a sample spinner and a 10-position removable sample changer. Epsilon 4 has an option to use in air mode, no vacuum system and no film consumables. To test the accuracy of the method 12 certified reference materials (CRM) of different geological matrices were prepared as fused beads. The results for the 11 compounds in the CRMs are shown in Table 2. For a wide range of sample types, the measured concentrations show excellent agreement with the certified values. Calibration results The calibration was set up using all 15 WROXI standards. The concentration ranges of the 11 compounds in the WROXI standards are shown in Table 1. Table 2.
