Concrete testing to new Irish Standard I.S. 465:2018

Concrete testing to new Irish Standard I.S. 465:2018

Petrolab has completed its first tests carried out in accordance with this recently published Irish Standard. I.S. 465:2018 is concerned with the assessment, testing and categorisation of damaged buildings made with concrete blocks containing certain deleterious materials (excessive quantities of free muscovite mica or pyrite) in Co. Donegal and Co. Mayo. The problem is similar in many respects to that of ‘mundic’ concrete degradation in the sout-west of England, and the petrographic examination requirements of the new I.S. draw upon those developed for the RICS Mundic Guidance by Petrolab and other petrographers. Petrolab is pleased to be able to apply its considerable 25 years+ experience in examination of ‘mundic’ concrete to look at this new...
Interactive Spreadsheet Reporting – Faster and Better

Interactive Spreadsheet Reporting – Faster and Better

Petrolab is pleased to announce some significant changes to its Automated Mineralogy (AM) service. Since the introduction of our AM service in 2015, we have built our reputation as a leading AM provider for the analysis of mine site and metallurgical test samples. Because we recognise that turnaround time (TAT) is increasingly important to our clients, Petrolab has invested in additional staff and equipment (a 2nd X-ray detector!) to enable more rapid preparation and analysis of samples. We have also developed an inter-active spreadsheet reporting tool – Automated Mineralogy Chart (AMC) – which will be our default format for reporting all analysis metrics. This spreadsheet tool operates as an interactive dashboard with a drop-down menu from which to choose the chart options. There are 9 possible options to select from (see Figure below), including graphing options such as bulk mineral abundance, elemental deportment or theoretical grade vs. recovery. As well as displaying the graph of choice it is possible to toggle off which samples are to be viewed side-by-side, down to and including the individual submitted size fractions. For...
Petrolab Welcomes Hannah Jenkins

Petrolab Welcomes Hannah Jenkins

Petrolab are delighted to welcome Hannah Jenkins. Hannah has a Bachelor of Science degree from Camborne School of Mines (CSM) in Applied Geology. As part of her time at CSM she was student mentor and after graduation went on the work as a Labroatory Assistant at CSM and then a data assistant at the Cornwall & Isles of Scilly Growth and Skills Hub. She joins Petrolab as part of the growing sample preparation laboratory...
Ride To Rome

Ride To Rome

Later this month our office manager, Aileen Barwell along with friends Wayne, Alessandro and Dot, will be attempting to ride from London to Rome to raise money for two charities, the first being The Royal British Legion, specifically for their projects supporting Admiral Nurses who work with people (and their families who are often more affected) with Alzheimers, which is a disease that took Wayne’s father at an early age. The second charity they are supporting is Demelza House, which is a hospice that provides respite care and end of life care for children with severe illnesses and life-limiting conditions. Petrolab is delighted to be one of the many companies sponsoring the venture which will be gruelling and challenging in its own right. Over the course of 17 days (26th of July – 13th of August), they will cover 1700 miles averaging 80-90 miles a day for most of the journey, including a punishing 45 miles a day through the Alps. In the course of the journey, they’ll ascend and descend the equivalent of 1.5 times the height of Mt Everest. We are...
Automated Mineralogy sparks interest of Petrolab visitors

Automated Mineralogy sparks interest of Petrolab visitors

Petrolab were delighted to welcome a delegation of mining industry visitors from Russia and Kazakhstan yesterday. Petrolab Director, James Strongman gave a presentation on the value of mineralogy in both exploration and operational settings and how Petrolab is utilising recent advances in automated mineralogy and correlative workflows to join with traditional optical microscopy and other complementary micro-investigative techniques such as...
The benefits of multicomponent mineralogical analysis – an example from the Isortoq Fe-V-Ti deposit.

The benefits of multicomponent mineralogical analysis – an example from the Isortoq Fe-V-Ti deposit.

The R500 Isortoq project in South-West Greenland contains two titanomagnetite-rich troctolite veins striking 15 km with an inferred resource of 70 Mt and potential products of Fe, Ti and V. As with many modern exploration assessments there is a need to quantify the mineral proportions of the ore, along with the key mineral carriers of the target elements. For any complex ore where the target elements are hosted at different concentrations, in different minerals, this process of characterisation usually necessitates using multiple techniques. Generally, the concentrations of vanadium in vanadiferous titanomagnetite deposits are low (0.3 – 1.9 %V2O5) and mostly contained as solid-solution with vanadiferous titanomagnetite. It is normally recovered as a co-product with major elements Fe and Ti, which themselves may be hosted by multiple other phases. As such the assessment of mineralogy particularly benefits from combining techniques to resolve the overall mineralogy, trace element and major element deportment and liberation characteristics (Figure 1). Figure 1: Comprehensive Mineralogical Characterisation In isolation, any one of these techniques would be insufficient. Although deductions may be made, assays on their own...
