LKAB starts core logging automation, digitalisation process with Minalyzer CS

LKAB has become the first iron ore miner in the world to implement the continuous XRF scanner Minalyzer CS, starting the process of automating and digitalising its drill core logging workflow.

By collecting data in an automated system, LKAB is aiming to improve the consistency and efficiency of its core logging process, Minalyze said.

LKAB and Minalyze initiated the collaboration in March 2020 when the first scanner was installed at the Kiruna iron ore mine for a test. It was then expanded to Malmberget where data from the Minalyzer CS was used to help geological logging of the drill core. The focus for the tests was to assess the datasets: geochemistry, high resolution images, RQD and specific gravity generated by the scanner and to determine how these datasets can assist in the core logging process.

Following these developments, the two companies plus Sentian, in May 2021, said an artificial intelligence application developed by the trio would be trialled to make drill core analysis faster, with the time to evaluate a drill core reduced from weeks to minutes, with increased accuracy.

LKAB Senior Vice President Exploration, Strategy and Business Development, Pierre Heeroma, said: “The tests with the Minalyzer in Kiruna and the more complex Malmberget geology confirmed that this Swedish technology is disrupting the core logging process – now we have fast access to rich data as guidance when classifying the rocks. Our core logging is now consistent and efficient.”

Annelie Lundström, CEO Minalyze AB, said: “The rest of the iron ore industry should closely follow the transformation LKAB is undergoing. With the Minalyzer they have one of the more automated and digitalised core logging workflows in the world. And they are setting a new world standard for sustainable mining with the fossil-free iron ore and steel making.

“We are very proud to be part of LKAB’s transition into the future.”

LKAB to trial AI-backed XRF drill core logging with help of Minalyze and Sentian

LKAB, Minalyze AB and Sentian say they have joined forces in a consortium to develop the latest technology for scanning drill core.

In March 2020, LKAB started a test with the Minalyzer CS drill core scanner where the goal was to improve the workflow for core logging – ie how the results of exploration drilling are analysed. The test led to a permanent installation in Kiruna (Sweden) and expansion to Malmberget where data from the Minalyzer CS is used to help geological logging of the drill core.

The consortium of LKAB, Minalyze and Sentian are now set to take the use of data to the next level when boreholes in LKAB’s deposits are to be investigated. The new artificial intelligence application being developed by the trio will make the analysis much faster, with the time to evaluate a drill core reduced from weeks to minutes, with increased accuracy.

This could see Minalyze’s X-ray Fluorescence-backed CS scanner analyse LKAB drill core while leveraging Sentain’s industrial artificial intelligence solutions to make real-time decisions relating to drilling and exploration activities.

The technology development driven by the consortium will be a world first, changing the entire industry, the companies say.

Jan-Anders Perdahl, Specialist at LKAB’s Exploration Department, said: “With the collaboration, the core logging takes a big step through machine learning and artificial intelligence. The geologist can, at an early stage, place greater focus on the parts of the core that show chemical or other changes. Opportunities are opened up to gain increased knowledge about ore formation processes and alterations in a completely different way than before. One can also get indications that you are close to mineralisation and where it may be located, and thereby streamline exploration.”

The technological leap will give LKAB’s staff increased competence, increased quality in and efficiency of the work, as well as reduced need for other analysis methods, according to the companies.

Annelie Lundström, CEO of Minalyze AB, said: “We are at an interesting time when the hardware to extract consistently high-resolution data from drill cores is available and we can now take the next step and generate value from data together with our customers. In this collaboration, we will develop algorithms that can map rock layers in so-called lithological logs with very high confidence. This can only be done by combining expertise from all three parties.

“The results from our collaboration will forever change how drill core logging takes place everywhere and will result in a more efficient, non-subjective and consistent process.”

Martin Rugfelt, Sentian CEO, added: “We see great power in the application of modern artificial intelligence to data from the mining industry and there is major potential in further combining our machine learning technology with Minalyze’s unique capabilities in data collection and analysis.”

SGS pairs portable instrumentation and machine learning with FAST

SGS has announced a new service for the metals and mining industry, Field Analytical Services and Testing (FAST), in North America and Australia.

FAST provides real-time data acquisition in the field by pairing portable instrumentation and machine learning, according to the company, which used the backdrop of the annual Prospectors and Developers Association of Canada show, in Toronto, Canada, to make the announcement. “It will bring instrumentation into the field, provide data within 24 to 48 hours and, with the use of machine-learning, enable real-time decision-making capabilities for clients,” the company said.

Part of the solution includes Minalyze AB’s Minalyzer ED-XRF core scanning technology, according to the company.

Russ Calow, Vice President Global Analytical Services, Minerals at SGS in Canada, said: “This service offering will allow our clients to optimise their exploration programmes and production procedures, while making rapid decisions that support quicker speed-to-market.

“SGS is committed to providing analytical procedures that yield meaningful, reliable data – while integrating our in-house, industry leading machine-learning capabilities to give innovative, field based solutions to our clients.”

SGS calls itself the global leader in the geochemical laboratory analytical testing sector with over 160 geochemical laboratories in 45 countries. Its FAST solution reflects a commitment to servicing the mining and smelting industries throughout the entire value chain, leveraging leading technologies, according to the company.

“SGS operates on-site and near-site laboratories in some of the most remote locations in the world, regardless of the climate, the altitude, the logistics or the sample volume,” the company said.

“Whether requirements are at the mine site or in metal smelting and refining plants, SGS has the experience, technical solutions and laboratory professionals to help clients maximize value from their operations and reach their goals efficiently and effectively.”

SGS services to the minerals sector include geochemical analysis, resource calculation, mineralogy, metallurgy, engineering, process design and engineering, process control, water treatment and trade services.
