​ 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. We take care of your needs from instrumentation to CRMs to tailored standards For the mining and minerals industry, Malvern Panalytical has specially developed a unique set of 15 synthetic, multi-element wide-range oxide known as the WROXI standards.

Coal trading is a very competitive landscape. While end customers buy the quality of coal based on what is compatible with their boilers and furnaces, the traders need to be vigilant in sourcing and supplying right grades. Buyers impose price discounts if the coal’s calorific value and other key parameters fall short of expected values. To secure the contracted revenue and avoid any discounts, exporters typically tend to supply higher grades than necessary. This in turn eats into their profit and erodes margins. Price penalties are also put in place if exports exceed the specific amount of moisture in the coal, since the moisture adds to transportation costs. Not to mention that since exports are typically global and long distance, breach of moisture limits can pose stability issues to the ships. In the worst-case scenario, such shipments at the port could even be rejected. In this article we share the idea about how coal mining companies, traders, and end-customers can achieve a "happy buyer-happy seller" agreement. Benefits Coal Mining: Ash, ash composition, Sulphur, total moisture, and calorific value are critical information to decide value of the coal Avoid penalties by meeting the contractual specifications of the coal Bring down the production cost and improve yield Grade-wise stockpiling of the coal and Perfect blending in accordance with end customer specifications Coal Plant: Incoming check of grades to verify specifications Verification of consistency or intrinsic deviation of the whole lot of material Optimization of coal yard management Blending of coal to target quality Optimize waste by safe use of low cost / low quality coal Bunker feed control in power plants Optimization of combustion parameters for boilers Assurance of optimal running conditions of boilers Minimize slagging and clinkerisation of ash in the boilers Reduced maintenance costs through minimal derating and boiler outages   About CNA Coal CNA Coal has been designed for tough environments of mines, featuring the cutting-edge Sodern neutron technology with unmatched lifetime and stable neutron output (D-T PFTNA).
