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.”
