Today’s cyclodextrin is a unique practical application by CYCLADEX INC that many of you may not know: the recovery of precious metals such as gold, silver, platinum, palladium, and rare earths from precious metal-bearing materials.
Cycladex has developed a series of technologies for the isolation of important metals, including gold, silver, and, its newest discovery, a process for lithium. The Technology has been scaled up in our demonstration plant in the US, and the results show significantly lower costs with environmentally friendly chemicals and excellent yields.
In this setup, cyclodextrins are added to the alkali metal/metal bromide solution to precipitate a metal cyclodextrin complex.
