Imaging and Analysis of Microcrystals

Imaging and Analysis of Microcrystals

The vast majority of our work involves the preparation of 30 mm polished blocks for quantitative analysis. However the Zeiss Mineralogic system is also perfectly geared towards the analysis of unpolished micromounts. This can be very useful when the sample mass is very low and preparation in epoxy resin would lead to the likely loss of the overall sample. Equally, it can be very useful on occasion, and particularly with small samples, to preserve any crystal habits as useful indicators of mineral speciation. Some recent examples of micromount analyses are shown below. Euhedral edge of a shattered cassiterite crystal. Partially intergrown with saccharoidal feldspars these cassiterite crystrals were collected from...

Petrolab welcomes Bill Jeffery

Petrolab are delighted to welcome Bill Jeffery who has joined us for the summer on a short-term contract to assist with a number of projects. He recently completed his MGeol in geology at Plymouth university where he received the Mineralogical Society undergraduate price. Whilst there he worked as a research assistant on the SEM analysis of platinum group-minerals from the Shetland ophiolite complex which brought experience of sample preparation and SEM analysis. He recently completed a 5 month internship at the Drakelands mine doing core...
Process Mineralogy 2017

Process Mineralogy 2017

Petrolab are proud sponsors of Process Mineralogy 2017 in Cape Town next week and have the privilege of presenting two papers at the conference. The first presentation is on the optimization of automated mineralogy for operational mine-site applications. Automated mineralogy systems have been around for over 20 years now but this presentation looks at the next paradigm shift in the application of this technology into operational contexts. Effectively using automated mineralogy on mine-sites has had to overcome three substantial hurdles. This has been (i) the presence of a sufficiently ruggedized system for mine-site deployment; (ii) the turnaround times, dependent on slow sample preparation, slow data acquisition and slow data interpretation, and (iii) the complexity of the systems that have often required (expensive) off-site specialists for implementation and running. Our paper explores solutions to these challenges and presents different case studies that it could be applied to (including one case study where it is being applied). The full abstract is below.   Optimising Automated Mineralogy for Operational Mine Site Applications. Strongman, J*., Brough, C*., Fletcher, J*., Garside, R*., Prinsloo, A’. & Tordoff,...
Job Opportunity – Software Engineer

Job Opportunity – Software Engineer

We currently have a temporary position available for an experienced Software Engineer. MAIN PURPOSE The postholder will work to continue the development of version 2 of a reporting application for the Carl Zeiss Microscopy Mineralogic Mining system. This is a temporary post with an expected project duration of approximately 2 months (full-time), though possibly longer. PROJECT BACKGROUND A WPF/ C#/ SQLite reporting application to be used to summarise, view and compare large mineralogical data sets produced by automated mineralogy using a scanning electron microscope and the Zeiss Mineralogic system. Data comes from analysis of a mineralogical sample (or samples) and consists of data on particles, made up of one or more grains. Each grain / particle has shape (morphometric) and composition (elemental) data. The overall goal of the reporting application is to streamline the workflow for calculating and producing summary project output (in the form of custom tables, charts and images) from Mineralogic output data in a reproducible and efficient manner. For more information and to apply, please e-mail petrolab@petrolab.co.uk to request an application...

Job Opportunity – Junior Mineralogist

UPDATE (16/01/2017): Thank you for all the interest in this position. This vacancy has now been filled. We are hiring! We currently have a place available for a junior mineralogist working primarily in our sample preparation laboratory and with our routine mineralogical tests. MAIN PURPOSE The postholder will work under supervision to assist in the preparation of sections from geological and construction materials for microscopic analysis. This is a position that will require routine operation and maintenance of precision machinery to cut, grind and polish materials. The postholder will also undertake routine mineralogical and petrographic tests under supervision, including recording and preparing samples for testing, and operate scientific instrumentation and software (e.g. scanning electron microscope, Mineralogic automated mineralogy system, optical microscopes) to analyse a broad range of materials. LOCATION This post will be based primarily at the company office at Redruth. The postholder will also be required to collect and deliver materials and use other sample analysis/preparation equipment based in the south-west region (Cornwall & Devon). Occasional visits to client sites and conferences will also be required. To apply,...
