LKAB Minerals Oy achieves Responsible Minerals Assurance Process conformance for phlogopite mica
We are proud to announce that LKAB Minerals Oy in Finland has successfully completed the Responsible Minerals Assurance Process (RMAP) for phlogopite mica. This achievement confirms our conformance with the Responsible Minerals Initiative’s (RMI) assessment standard, positioning LKAB Minerals among only three mica producers worldwide to hold this recognition.
The RMI, with more than 500 member companies, is one of the most respected global organisations dedicated to advancing responsible mineral sourcing in supply chains. Its flagship RMAP programme provides independent, third-party verification of smelter and refiner sourcing practices, focusing on high-impact points in global supply chains.
At our Siilinjärvi site, the assessment evaluated management systems, sourcing practices, and due diligence processes to ensure they align with RMAP standards for responsible sourcing, workplace practices, environmental safeguards, and health and safety.

A milestone for our mica business
This conformance is a significant step for LKAB Minerals and reflects our long-term commitment to responsible mineral supply chains. It enhances confidence for our customers across industries that phlogopite mica from LKAB Minerals Oy is sourced and processed in line with rigorous international standards.
“Being recognised as RMI conformant is a milestone for our mica business, and it demonstrates our dedication to responsible sourcing. We are proud to be part of a small group of producers globally setting this benchmark for the industry,” said Isla van der Woude, Business Development Manager at LKAB Minerals Oy.
The RMAP conformance ensures that our customers can trust in both the quality of our minerals and the responsibility of our sourcing. It further reinforces LKAB Minerals’ role in supporting industries with materials that meet strict technical and ethical standards.
