In this work, rubidium-bearing biotite (Rb-BB) was adopted to efficiently extract Rb through ion exchange. The influences of experimental conditions on the Rb leaching efficiency (Le (Rb)) were explored in detail.

It was reported that rubidium was more difficult to extract than other alkali metals (Stepanov et al., 2012, Zhou et al., 2015). But, the methods and experiences in the extraction of other alkali metals could be referenced for the extraction of rubidium (Luong et al., 2014, Yan et al., 2012a, Yan et al., 2012c), among which chlorination roasting–water leaching is the major …

Abstract Two methods including roasting-water leaching and direct acid leaching, were comparatively studied for the extraction of rubidium from the rubidium-bearing biotite. The leaching behaviors were investigated and optimized conditions were then obtained. For chlorination roasting-water leaching, the maximal rubidium extraction was obtained with a yield …

La biotite et la muscovite sont deux minéraux étroitement liés qui appartiennent au groupe des micas de minéraux silicatés en feuille. Bien qu'ils partagent certaines similitudes, ils présentent également des différences distinctes en termes de composition chimique, de propriétés physiques et d'occurrences géologiques.

L'extraction à ciel ouvert se fait par paliers. ... La tonalité verdâtre est due à la présence de glauconite (accessoirement à la présence de chlorite et biotite chloritisée) ; elle est d'autant plus marquée que les grains glauconieux sont plus gros : ce sont donc les grès grossiers (« molasse bleue ») qui sont le plus colorés (la ...

Four different agents (CaSO 4, CaCl 2, NaCl and CaCO 3) were selected to compare on the extraction of rubidium.As shown in Table 2, chlorinating agents had higher rubidium extraction yield than those of other roasting chemical agents.The rubidium extraction yields for CaCl 2 and NaCl were 93.98% and 44.79%, respectively, which were attributed to …

It was found that all the strains had the abilities to enhance the dissolution of biotite, and P. oxalicum showed the highest K release amount among seven tested strains. Owing to lack of soluble potassium resource in some countries, it will be the competitive alternative to obtain potassium from insoluble K-bearing minerals (e.g. K-feldspar, biotite) in order to satisfy the …

The rubidium leaching process from biotite generates a large amount of waste materials that should ideally be reused for heavy metal ion adsorption so as not to create environmental problems.

Two methods including roasting-water leaching and direct acid leaching, were comparatively studied for the extraction of rubidium from the rubidium-bearing biotite. The leaching behaviors were invest

Experiments were carried out in a shaker (30 °C, 180 rpm) with biotite directly dispersed in the leaching medium or enclosed in a dialysis bag.
