Effect of Chain Length Compatibility of Alcohols on Muscovite Flotation by Dodecyl Amine

, 2018
A portion of dodecyl amine (DDA) in a muscovite flotation system was replaced with alcohols with different carbon-chain lengths. These alcohols included octanol (OCT); decanol (DEC); dodecanol (DOD); and tetradecanol (TER).

The ‘State Patriotic Turn’: State Ideology and History According to the Russian Military Historical Society, 2022–2024

Nations and Nationalism, EarlyView.
ABSTRACT The Russian Military Historical Society (RMHS) was founded in 2012 on President Vladimir Putin's orders. Since Russia's invasion of Ukraine in February 2022, the society's members have not only published propaganda to support the ‘special military operation’ but have discussed the need for a proper ‘state ideology’.

Assessing pegmatite compositional evolution through analysis of muscovite from historic North Carolina mining districts by handheld laser-induced breakdown spectroscopy (hLIBS)

Frontiers in Physics
Mineral exploration provides the commodities society requires, but continuing discovery and development of new critical mineral deposits is necessary to realize a sustainable, low-carbon future.

Development of unfired earthen building materials using muscovite rich soils and alkali activators

Case Studies in Construction Materials, 2019
Most studies have focused on the alkali activation of thermally activated kaolinitic clays for the production of innovative building materials. Whilst the widespread use of these minerals may be hindered due to geographical availability; a combination of

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Age of formation of gold-sulfide-quartz veins in the Kizas ore field, Shamansky ore cluster, Western Sayan, based on 40Ar/39Ar data

Руды и металлы
The Kizas ore field formed by deposits of the Early Cambrian Shaman Formation is characterized by an amagmatic structure and is notable for its anomalously high placer gold potential: over 22 tonnes of placer gold have been extracted throughout its ...

Siliceous sponges or seawater as a silicon source? Tracing silicon burial pathways of the Upper Cretaceous opal‐CT deposits using δ30Si and δ7Li

Sedimentology, EarlyView.
ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

Terra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...
