About
The objective of this project is to develop GAME for efficient and cost- effective extraction and purification of low-concentration, high-value metals from complex streams. The successful development of this technology will contribute to the production of high- purity precious metals from end-of-life PCBs of various sources. GAME uses three phases (aqueous, organic, and gas) to achieve an efficient separation in a confined microchannel.
