Invention Reference Number
91°µÍø has developed an advanced spectroscopic screening method to evaluate the flotation of potential earth element (REEs) ores. This technique enables rapid, non-destructive assessment of collector adsorption on mineral surfaces, streamlining the discovery and optimization of floatation agents for REE.
Description
This invention introduces a high-throughput screening platform using surface-sensitive spectroscopic tools to assess the adsorption behavior of flotation reagents – particularly aromatic hydroxamic acids – on rare earth-bearing minerals such as monazite. The methodology enables precise quantification of reagent-surface interactions under variable chemical conditions. By integrating complementary spectroscopic measurements, the system offers a robust means of evaluating collector performance without relying solely on traditional bulk flotation tests. This approach reduces the time and material required for reagent screening and provides mechanistic insights that guide collector design and selection for rare earth extraction.
Benefits
- Rapid evaluation of flotation reagent effectiveness
- Reduced need for time-consuming bulk flotation experiments
- Enhanced understanding of surface interaction mechanisms
Applications and Industries
- Rare earth ore beneficiation and process development
- Mining, minerals, and extractive metallurgy industries
