Qmineral runner-up in Reynolds Cup Competition 2024
22 May 2025

Qmineral has achieved second place in the 2024 edition of the prestigious Reynolds Cup Competition, the world championship for quantitative mineralogy, in competition with 105 laboratories worldwide. After two consecutive first places in the last two editions we could participate in (2016 and 2020), Qmineral confirms its highly precise and accurate mineral analysis capabilities and hereby remains the most accurate commercial lab for mineral identification and quantification on all material types.
Although we finished runner-up in this edition of the Reynolds Cup, Qmineral still provides world-class accuracy for both non-clay minerals (0.3-0.4 wt% error) and clay minerals (1.2 wt% error). We missed the first place by just 1.0% bias, which is the lowest difference for the 1st place in the history of the Reynolds Cup.
The three samples that were distributed amongst the different laboratories were a kaolin clay (14.0% bias on 11 crystalline minerals, 1 amorphous phase and 5 clays), a brown bentonite (15.8% bias on 9 crystalline minerals, 1 amorphous phase and 4 clays) and an Old Red Sandstone (6.8% bias on 13 crystalline phases and 4 clays).
The accuracy of mineralogical data makes a substantial difference, not least because errors propagate into calculations and models that are based on the data. A Reynolds Cup ranking in the top 3, therefore makes a significant difference compared to lower rankings. We strive every day to keep on delivering state-of-the-art quality mineralogical data, with fast turnaround times at competitive rates.

Join us on the 17th of June at 4PM (GMT+2) in our free webinar where we will elaborate on:
- The mineralogical accuracy and systematic lab errors identified over multiple Reynolds Cup editions (including 2024)
- Qmineral's innovative on-site FTIR solutions for rapid mineral, clay mineral and organic characterization
