At SQM, we valued our experience with Erzlabor due to their technical expertise and methodology to address spatial variability of the ore. This enabled us to select representative samples and advance in predictive mineralogical analysis with a high level of detail, clearly distinguishing them from other service providers.”

ERZLABOR’s timely and crucial mineralogical analysis, i.e., MLA and TIMA were instrumental to the success of our projects. Detailed data on the mineralogy, liberation, and association of our ore samples allowed us to optimize grinding for the target liberation size and determine the suitable flotation reagent regime (such pH modifiers, activators, depressants, and collectors).”

“Our primary goal in working with Erzlabor was to obtain accurate, reliable, and timely material analyses to support our projects in rare earth elements and other critical raw materials. A deep understanding of mineralogical and chemical composition is the foundation for the development of UIT’s tailored, resource-efficient hydrometallurgical and process solutions for our customers.

Erzlabor’s technical expertise, attention to detail, and ability to adapt analytical methods to complex and uncommon material types have been invaluable in achieving these goals. The clear and well-structured reports, combined with their openness to discuss results, have given us exactly the insight needed to design and validate optimized process routes. Their analyses provided the basis on which we could develop innovative approaches for the extraction and purification of critical materials.

What sets Erzlabor apart from other providers is their deep technical understanding of complex mineral and material systems and their collaborative approach. Where many laboratories deliver raw data, Erzlabor ensured that their work was aligned with the specific objectives of our projects. This proactive mindset, combined with their ability to handle unusual and challenging samples, made a decisive difference to our project outcomes.
Throughout our collaboration, the Erzlabor team has shown a strong ability to address our needs quickly and thoroughly. Queries were answered with well-considered explanations, and the partnership was marked by professionalism and trust.

We would rate Erzlabor a 5 out of 5 and already recommended them without hesitation to any partner seeking precise and insightful material characterization. Their analyses have been a cornerstone for us in developing economic and sustainable process solutions for critical raw materials—an area where efficiency, selectivity, and technical reliability are essential.

“At SQM, our goal was to obtain a reliable mineralogical characterization that could be integrated into a geometallurgical model for caliche ore. The collaboration with Erzlabor allowed us to achieve this objective by providing precise and consistent information to support the development of our model. We valued our experience with Erzlabor due to their technical expertise and methodology to address spatial variability of the ore. This enabled us to select representative samples and advance in predictive mineralogical analysis with a high level of detail, clearly distinguishing them from other service providers. For SQM, the Erzlabor team demonstrated great flexibility and commitment, supporting the project from the early stages with sample selection and preparation under a waterless system capable of identifying soluble salts. We also highlight their ability to respond promptly and effectively to our technical requirements. At SQM, we recognize the value of their specialized expertise in non-standard minerals such as caliche ore, which represents a significant contribution to strengthening our characterization of resources and geometallurgical modeling processes.

“ERZLABOR’s timely and crucial mineralogical analysis, i.e., MLA and TIMA were instrumental to the success of our projects. Detailed data on the mineralogy, liberation, and association of our ore samples allowed us to optimize grinding for the target liberation size and determine the suitable flotation reagent regime (such pH modifiers, activators, depressants, and collectors). The particle-based model provided by the Helmholtz Institute Freiberg HIF and in collaboration with ERZLABOR allowed us to demonstrate the capability of pneumatic Imhoflot cells (V-, H-, or G-Cells) in recovering of fine and ultrafine particles.

Dirk and Sebastian were easy to communicate with and focused on meeting our specific requirements. Their close attention to detail was crucial for understanding the mineralogical constraints of our project. The ability of the Erzlabor team to address our needs and respond to our queries is very good. We would rate Erzlabor a 4.5 out of 5 and already recommended them.

“Our main goal in working with Erzlabor was to ensure consistent, high-quality sample preparation for our material — a critical step in obtaining accurate analytical results for orebody characterisation and geometallurgical testing. Erzlabor helped us achieve this by delivering sample prep services that were not only technically sound but also aligned with international best practices. Their attention to detail, strict QA/QC protocols, and traceability gave us full confidence in the integrity of our samples and downstream data.

What made Erzlabor stand out was their precision and consistency in sample preparation. Unlike other labs where variability in sample handling and preapration can lead to inconsistent results, Erzlabor maintained a high level of uniformity across all provided materials. Their team communicated openly throughout the process and took a flexible, client-oriented approach that adapted to our specific requirements, including tight timelines and batch-specific instructions.

The Erzlabor team demonstrated excellent technical competence and responsiveness. Whenever we had specific questions or needed to clarify timelines, they responded quickly and thoroughly. Their willingness to adapt to clients needs reflected a strong commitment to service quality and client success.

We would highly recommend Erzlabor to any mining operation looking for reliable, high-quality sample preparation. Their consistency, technical rigor, and client focus make them a standout partner in the field.
