2nd EDS Detector!

2nd EDS Detector!

Last week saw the visit of Bruker to fit our second EDS detector (the xFlash 6|60) and upgrade the analytical software. The additional detector allows Petrolab to acquire spectra simultaneously on two detectors reducing the time required to reach an acceptable level of counts for mineral identification. There are further added benefits in improving edge effect analysis and allowing more versatile analysis options on samples with topography. Finally, the software upgrade from Esprit 1.9 to 2.1 for the Bruker software brings added power and utility for element mapping and quantification. All-in-all the upgrades are an exciting development for Petrolab allowing us to increase sample throughput, analyse a wider range of sample morphologies and with greater analytical versatility on point & shoot job requirements.  ...
Petrolab welcomes Libby Rose

Petrolab welcomes Libby Rose

Petrolab are delighted to welcome Libby Rose. Libby has a First-Class Honours degree in Geology and was awarded a MSc with Distinction in Mining Geology at Camborne School of Mines in 2017. She went on to complete an internship at CSIRO on their CMR Discovery Internship Program in Perth, WA. Here she studied the hyperspectral infrared spectral data from multiple komatiite drill holes hosting nickel, and then carried out and compared Tornado x-ray fluorescence element mapping, scanning electron microscopy, and more detailed infrared microscopy....
Mineralogic 101 – Complex Outputs

Mineralogic 101 – Complex Outputs

In the previous Mineralogic 101 post, we covered the general outputs available in Mineralogic through the Reporter software. However, there are further outputs that can be generated from the raw database either through SQL modeling or Microsoft Excel. Taken together these outputs improve the visualisation of complex data, enabling the client to obtain useful information on the data relevant to their mineral processing, environmental mineralogy or tailings control. Grain Size Distribution Further detailed liberation analysis, in particular Theoretical grade-recovery curves Liberation yield bar charts Theoretical mineral-recovery curves Mineral association data These complex outputs are more important when the minerals textures are playing (or may play) an important role in limiting processing performance. Often (but not always), difficulties in processing boil down to liberation issues which is why there are several different tools available for visualising liberation characteristics within a sample.   Grain-size distribution (GSD) This analysis returns the GSD of target phases and the overall particles. Although not a direct measure of liberation it is a very useful tool for visualising distributions that may explain poor recoveries. Often, in tailings, the target phase is fine-grained...
Comminution 2018

Comminution 2018

Petrolab and iMin Solution Director James Strongman will be attending MEi Conferences Comminution 2018 at the Vineyard Hotel, Cape Town from April 15th to Aptil 19th. As part of this conference week, he will be presenting at Grinding Solutions pre-conference Seminar, talking about “Mineralogy, Metallurgy and the Mine Site” (see abstract below). Full details of this free seminar can be found on Grinding Solutions homepage (https://www.grindingsolutions.com/events/cape-town-seminar-april-18/). With on-site automated mineralogy, increased computing speed and ruggedised sensors the dream of monitoring and controlling mineral processing plants using mineralogy rather than chemistry is fast becoming a reality. This free seminar aims to show the journey that Grinding Solutions, Zeiss, iMin Solutions and IntelliSense.io believe is the future.   Mineralogy, Metallurgy and the Mine Site. Strongman, J*., *iMin Solutions and Petrolab Ltd Limited Director Corresponding Author: jstrongman@iminsolutions.com; james@petrolab.co.uk Abstract In mineral processing, operations are increasingly seeing the benefits of moving into the digital age, with increased use of “big data” systems. The development of automated mineralogical techniques and specifically site-based capability gives the mineral processor a unique window into the process, allowing them to ground their understanding of metallurgical response through the underlying mineralogy....

Petrolab welcomes Mariola Zając

Petrolab welcomes Mariola Zając

Petrolab are delighted to welcome Mariola Zając. Mariola has recently completed her Masters at AGH University of Science and Technology having previously completed a Bachelors degree at the same university. Her courses included ore mineralogy, mineralogy and petrology. She has also completed work experience at Amarante Investments looking at base metal exploration in Lower Silesia. As part of this work she obtained a qualification as an assistant driller. She is multi-lingual which should prove useful to Petrolab’s increasing number of worldwide...
