Lithium minerals become a sub-economic raw material for lithium production to fulfill the demand. This study is about extraction from mica schist using roasting and leaching processes. The located in Kebumen, Indonesia was used phenomena during process. Sodium sulfate as agent while 0.36 M sulfuric acid agent. Solid/liquid ratio (1:5, 1:10, 1:15 1:20 (g/mL)) time (30, 60, 90 120 minutes) were v...

This study discussed production, demand, and future prospects of rubidium, which is an alkali group metal that highly reactive to various media requires carefulness in handling, but no significant environmental hazard rubidium has been reported yet. Rubidium used fields such as optoelectronic equipment, biomedical, chemical industries. Because difficulty production well limited the transaction ...

Highly fractionated granites and related magmatic-hydrothermal ore-forming processes can be traced by elemental ratios such as Nb/Ta, K/Rb, Y/Ho, Sr/Eu, Eu/Eu*, Zr/Hf, Rb/Sr. The lanthanide “tetrad effect” parameter (TE1,3) also a useful geochemical fingerprint of highly granites. This work assesses its application an exploration vector for granite-related mineralization in the Central Iberian ...

Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining metallurgical industry Eastern Kazakhstan. To substantiate scientific background exploration, we study microinclusions minerals from rare-metal fields, as well trace-element patterns ores their hosts that may mark mineralization. The revealed compositions gold-bearing sulfide a number typ...

-Hydroxyl orientation has a major influence on the strength of the ionic interlayer bonding in micas because of the strong repulsion between the hydrogen and the interlayer cation (IC). In order to determine if other factors also influence the magnitude of the interlayer bond energy, the effect due to the varying H-IC distance, as one finds, for example, between a dioctahedral and a trioctahedr...

A significant proportion of Europe’s lithium endowment is hosted by unconventional resources such as rare-metal granites (RMG) which the Beauvoir granite in France a prime example. In hard-rock deposits, where mostly micas (lepidolite, zinnwaldite), ability to assess whether can be extracted economically from ore essential and requires comprehensive understanding mineralogical properties deport...

The purpose of the study was to investigate the mineralogical and Heavy Metals (HMs) present in the granite mining soils in Chimakurthy, India. The mineral exploration of mining soils were identified by X-Ray Diffractometer (XRD) pattern analysis. However, the morphological features and quantitative HMs were detected by Scanning Electron Microscopy/Energy Dispersed Spectroscopy (SEM/...

The existence of diagnostic features in the visible and infrared regions makes it possible to use reflectance spectra not only identify mineral assemblages but also for calibration classification satellite images, considering lithological and/or mapping. For this purpose, a consistent spectral library with target minerals rocks is needed. Currently, there big market pressure raw materials inclu...
