Ruthenium deposition by hydrothermal

Webformation of REE ores, in many deposits the REE have been remobilized by hydrothermal fl uids, and some are almost exclusively hydrothermal in origin. Genetic models for the hydrothermal transport and deposition of the REE generally assume that the REE are transported mainly as fl uoride complexes. This is partly because of a common association WebSep 26, 2024 · Ruthenium is electrodeposited for the first time from a deep eutectic solvent based electrolyte composed of ethylene glycol and choline chloride in 1:2 molar ratio.
