Separation of GaCl3 from AlCl3 by Solid–Liquid

2019-7-12  Hydrometallurgical processes, such as solvent extraction and ion exchange, are the main processes for the separation of gallium from these associating elements. (8,10,12−14) While established, these processes usually require multiple separation stages due to the similar affinity of these compounds to extractants and ion exchangers.

Resources and extraction of gallium: A review -

2017-12-1  1. Introduction. Gallium (Ga), a soft and silvery-blue metal, was discovered in 1875 by the French chemist Paul-Émile Lecoq de Boisbaudran (Moskalyk, 2003).With an average crustal abundance of 17 ppm, Ga is considered a trace metal (Redlinger et al., 2015).This element exhibits an extraordinarily wide temperature range in the liquid state due to its low melting point (302.98 K) and high ...
