Molecular Recognition Technology (MRT) is an innovative process designed for the selective separation and recovery of metals, particularly Platinum Group Metals (PGM) and Rare Earth Elements (REE). It employs custom-engineered molecular recognition agents, known as SuperLig® products, to selectively bind target metals within complex matrices. The technology stands out for its precision, efficiency, and eco-friendly attributes, making it a key advancement in green chemistry.
The primary strength of MRT lies in its unparalleled selectivity. By using SuperLig® products tailored to the chemical properties of specific metals, MRT achieves single-pass separations with exceptional purity levels, often exceeding 99%. This eliminates the need for extensive reprocessing or multiple separation steps. The process operates efficiently at ambient temperature and pressure, offering a sustainable alternative to conventional methods that rely on high energy input or hazardous chemicals. Furthermore, MRT uses simple and readily available eluent solutions such as water, hydrochloric acid, and sodium chloride, ensuring compatibility with existing industrial systems while maintaining operational simplicity.
MRT has proven its effectiveness in refining Platinum Group Metals, including platinum, palladium, rhodium, and iridium. By using highly specific SuperLig® products, MRT enables the precise separation of these metals even from solutions with high concentrations of impurities. For instance, iridium can be isolated in a single step using SuperLig® 182, while SuperLig® 190 facilitates the selective extraction of rhodium. These processes not only enhance the purity of the recovered metals but also significantly reduce the time and resources required for processing. Additionally, MRT aligns with green chemistry principles, minimizing waste generation and reliance on harmful solvents, which are common in traditional methods like solvent extraction.
The technology has also demonstrated exceptional capabilities in the recovery and purification of Rare Earth Elements. MRT enables the separation of REEs into light and heavy groups, followed by the individual extraction of specific elements such as dysprosium and yttrium. With recovery rates exceeding 99%, the process ensures minimal metal loss and maximizes economic value. Compared to conventional methods, MRT offers a simplified approach that reduces operational complexity, energy use, and environmental impact. Its ability to produce high-purity REE carbonate salts has been validated through successful pilot plant operations, highlighting its scalability for commercial use.
Compared to traditional metal recovery techniques such as solvent extraction and ion exchange, MRT offers significant advantages. Its high selectivity results in greater metal purity and recovery rates, while its simplified process design reduces the need for complex infrastructure and equipment. Unlike conventional methods that generate hazardous waste, MRT eliminates the use of organic solvents, reducing environmental risks and compliance costs. Moreover, the rapid processing times of MRT enable faster turnaround, lowering overall operational expenses and allowing for quicker delivery of recovered metals to market.
