INTRODUCING : X-RAY MINERAL SERVICES FINLAND OY

Published on 16 October 2020

X-ray Mineral Services (XMS) are excited to announce the establishment of a new office based in Helsinki under the trading name X-ray Mineral Services Finland Oy. XMS is part of the Hafren Scientific Group which also trades under the names Chemostrat and Origin Analytical.

This development follows on from the participation of XMS in the BATCircle project in co-operation with Finnish partners. The BATCircle project is a 22 M€ Business Finland initiative involving research into the circular economy of battery metals, the key objective of which is to find ways of adding value to the battery metals sector. This will be achieved by more efficient screening and utilisation of mineral resources, enhancement of the metal refining processes, more efficient recycling of battery metals, improved co-operation between the companies and research organisations, as well as through the identification of new business opportunities between partners.

X-ray Mineral Services has a long tradition as a company specializing in X-ray diffraction (XRD) mineralogical and X-ray fluorescence (XRF) elemental analysis. As part of the Hafren Scientific Group, it is now a multi-disciplinary materials analysis centre offering a suite of techniques including Inductively Coupled Plasma – Optical Emission Spectroscopy (ICP-OES), Inductively Coupled Plasma – Mass Spectroscopy (ICP-MS), Fourier Transform Infra-Red Spectroscopy (FTIR), Raman Spectroscopy and associated portable technologies that provide comprehensive mineralogical, elemental and textural analyses. In addition to considerable oil and gas experience the company has diversified into a natural resources analytical consultancy active in the extractive, geotechnical, environmental, recycling and academic sectors.

Hafren’s principal focus in the oil and gas sector is to de-risk exploration and enable wells to be drilled with increased success and reduced environmental impact. Hafren are extending this philosophy to the battery mineral value chain by establishing new analytical workflows for mineral, metal and material characterisation and thereby support the entire battery ecosystem. Hafren’s strategy is to migrate its analytical capabilities and skills from oil and gas to support green technologies and circular economies such as battery resources and environmental impact sectors.

"Our geoscience group believes that timely delivery of high-quality data in the laboratory, in the field and in the mine is at the heart of robust analytical  solutions and the Hafren Group has had considerable success in providing clients with practical solutions that do not compromise on quality," said Tim Pearce, Hafren Group MD.


During a visit to Helsinki earlier this year, Dr Tim Pearce, Stephen Jones and Dr Lorenza Sardisco were invited to the British Embassy to meet with Her Majesty’s Ambassador to Finland Tom Dodd to discuss business development opportunities between the UK and Finland, in particular the provision of geological services to Finnish-based organisations. Also present were Alan Butcher and Pasi Heikkilä of the Geological Survey of Finland (GTK).

 

The establishment of the new office in Helsinki will facilitate the company’s future participation in the development of Finland’s battery cluster. It will enable the business to develop close associations with Finnish mining companies and expand its expertise and services within other business sectors which may require geological services.

Prof. Pekka NurmiAs part of this expansion XMS Finland are very pleased to announce that Prof. Pekka Nurmi has been appointed as Senior Technical Advisor to represent the business in Finland. Pekka has over 30 years of experience in geosciences, management and the minerals sector. He has held several director and chief scientist positions at the Geological Survey of Finland and has been an Adjunct Professor in Economic Geology at the University of Helsinki. Pekka has promoted Finland’s mineral opportunities for the global industry for 25 years and led the preparation of Finland’s mineral strategy. Pekka has played a vital role in establishing major science and innovation programs, such as EIT Raw Materials, the Green Mining Programme and the Battery Cluster in Finland. Pekka’s publication list comprises approximately 90 contributions in scientific journals and books mainly related to economic geology, mineral exploration, sustainable mining and the minerals sector in general. Currently Pekka runs his own Tallinn based consulting and advisory firm Penurco OÜ, is a Senior Adviser at Aurora Exploration Services Oy and is also the Chair of the Board of Finland’s Natural Resources Research Foundation.


Wales and Business Development in Finland

Published on 19 December 2019

X-ray Mineral Services (XMS), a Welsh company based in Colwyn Bay, announces its recent participation in a collaboration with the Geological Survey of Finland (GTK) to promote and develop business links between the UK and Finland. As part of this initiative, two geologists with XMS, Stephen Jones and Dr Lorenza Sardisco, travelled to Helsinki this month to present a 1-day course on Quantitative X-ray Diffraction (QXRD) at GTK’s headquarters, organised by Alan Butcher, Professor of Geomaterials and Applied Mineralogy. The participants on this course included GTK geologists, and representatives from other companies based in the Helsinki area looking to improve their knowledge and understanding of the specialist analytical techniques which are used by XMS to identify and quantify ore types, and especially those associated with Battery Minerals.

As part of their visit to Helsinki, Stephen Jones and Lorenza Sardisco were invited to the British Embassy to meet with Her Majesty’s Ambassador to Finland, HMA Tom Dodd, to discuss business development opportunities between the UK and Finland, and in particular the provision of geological services to Finnish-based organisations by X-ray Mineral Services.

This development follows on from the participation of XMS and GTK in the BATCircle project – a 22 M€ Business Finland initiative, led by Aalto University, involving research into the Circular Economy of Battery Metals (BATCircle). The key objective of the BATCircle project is to find ways of adding value to the battery metals sector. This will be achieved by more efficient screening and utilisation of mineral resources, enhancement of the metal refining processes, more efficient recycling of battery metals, improved co-operation between the companies and research organisations, as well as through the identification of new business opportunities between partners.

The UK is facing an unprecedented energy challenge with the recent announcement that all combustion engines (petrol & diesel engines) will be progressively phased out by 2040 and replaced with electric vehicles. Current battery technology solutions require that minerals such as cobaltite (CoAsS), chalcopyrite (CuFeS2), spodumene (LiAl(SiO3)2), pentlandite ((Fe,Ni)9S8), and graphite (C) will all be required for the production of battery metals (Co, Cu, Li, Ni, C) and materials (anode, cathode, electrolyte). And yet world mining statistics all suggest that current known resources will not be enough to supply this anticipated huge demand. More battery minerals are therefore required to be identified from the UK, Europe and beyond.

X-ray Mineral Services is a company specializing in X-ray diffraction (XRD) mineralogical and X-ray fluorescence (XRF) elemental analysis for upstream oil and gas companies and large geological service consultancy groups. The company has also established a successful non-oil & gas analytical business with customers in the extractive, geotechnical, environmental, recycling and academic sectors and provides quality control data for tile, brick and ceramic manufacturers. In addition, it offers expert advisory services on mineralogical issues. The company is part of the Hafren Scientific Group which trades under the names Chemostrat and Origin Analytical.

"We are very excited to participate in this joint venture with GTK to promote the development of battery mineral resources in Europe." said Stephen Jones, General Manager of X-ray Mineral Services. "Our highly capable analytical and consultancy team based in North Wales will be able to actively contribute to the future improvement in battery technology solutions".

GTK is a leader in geoscience research with strategic objectives that include tackling major global challenges, such as questions related to sustainable production, circular economy, clean water, low-carbon energy and climate change.

Hafren’s principal focus in oil and gas is to de-risk exploration and enable wells to be drilled with increased success, reducing the number of wells drilled to drain a reservoir and thereby limiting the environmental impact. Hafren are extending this philosophy to mining and processing by establishing new analytical workflows to optimise exploration assessment by reducing the number of boreholes drilled and by improving mineral processing by identifying product contamination and development protocols for recycling materials and water. Hafren strategy is ultimately to migrate its analytical capability and skills from oil and gas to support green technology such as battery resources and environmental impact sectors.

"Our geoscience group believes that high-quality data is at the heart of robust geological solutions and the Hafren Group has had considerable success in providing practical solutions for clients that do not compromise on quality," said Tim Pearce, Hafren Group MD.

The Hafren Group wishes to acknowledge the continued support of the Development Bank of Wales and the Welsh Government. This development will further strengthen geoscience service provision, an important export sector, in Wales.

Sand from the Sahara

Published on 30 April 2019

We hope that you all enjoyed the warm Easter weekend!

Record-breaking temperatures in recent weeks were due to warm air being pushed up from low latitude, bringing with it a plume of dust arising from wind storms in the Sahara. The plume even reached Iceland! Managing Director Steve had to wash his (black) car due to seagull ‘emissions’, and was surprised later to find a covering of reddish-orange dust on the patch that he had recently cleaned.

Dust on car roof and filterThe science team was scrambled and we swabbed the area with a moistened filter paper to collect a sample on a flat surface for XRD as can be seen in the photograph.


Just 45 minutes later we had an analysis: peaks for quartz, feldspar, calcite, dolomite, illite and chlorite were clear as can be seen on the diffractogram below.

Diffractogram of Saharan Sand

We were impressed that we had good intensities and were able to quantify the material using Rietveld analysis. The results of this are shown in the table below: 

  Illite Chlorite Quartz Feldspars Calcite Dolomite
Mass % 14.9 6.2 41.3 24.7 9.2 3.7

 

There are some fantastic images of previous events that have been collected by the Earth observation satellites operated by NOAA for the USA Department of Commerce. Here is one showing dust streaming out across the equatorial Atlantic from June 2018.

Digging around uncovered some interesting papers on dust emissions. It has been estimated that around 240 million tons of such dusts are deposited annually on and around the Atlantic Ocean, and the iron which is contained is a critical nutrient for marine algae in surface waters, the basis of the food chain, of course.

Iron is often difficult to pin down using XRD, since the iron oxides and hydroxides which give colour to geological materials is of poor crystallisation, or even amorphous. It is no surprise that iron-bearing phases are not detected in this diffuse and low-density XRD preparation.

All great XRD interest, but the rain from Storm Hannah washed it all away in a trice.
