Bastnaesite, Barite, and Calcite Flotation Behaviors with Salicylhydroxamic Acid as the Collector

, 2020
The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calcium-bearing minerals.

Pelagic barite precipitation at micromolar ambient sulfate

Nature Communications, 2017
The question of how significant barite deposits were able to form from early Earth’s low-sulfate seas remains controversial. Here, the authors show pelagic barite precipitation within a strongly barite-undersaturated ecosystem, highlighting the ...

Low Chemical Weathering Intensity, Enhanced Erosion, and Euxinic Conditions Along the Norwegian Margin During the Paleocene‐Eocene Thermal Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Paleocene–Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a rapid global warming event marked by intensified hydrological cycling, enhanced continental weathering, and widespread ocean deoxygenation. Although the extent of anoxic basins during the PETM is relatively well documented, the contribution of high‐latitude continental weathering to ...

ENRICHMENT OF MASSIVE SULFIDES FROM THE SEMENOV HYDROTHERMAL CLUSTER (MID-ATLANTIC RIDGE) IN BARITE: A RESULT OF E-MORB INVOLVEMENT AND MAGMATIC CONTRIBUTION [PDF]

Минералогия
The paper reviews and compares the barite findings in hydrothermal fields of the midoceanic ridges. The genetic significance of barite is considered for the Semenov hydrothermal sulfide cluster associated with an oceanic core complex (OCC) at 13°30′ N of

Establishment and validation of a FLUKA radiation model for a medical electron linear accelerator room based on a virtual source

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Purpose In Monte Carlo (MC) simulations of medical electron linear accelerator (linac) rooms using FLUKA, time‐consuming modeling and simulation of the accelerator head are typically required, and FLUKA cannot directly read the phase space files (PSF) for accelerator heads provided by the IAEA.

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Evaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature [PDF]

Journal of Petroleum Science and Technology, 2017
Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids.

Geochemical characteristics of the barite deposits at cold seeps from the northern Gulf of Mexico continental slope

, 2011
Although less common than the occurrence of authigenic carbonate, barite has been observed frequently at cold seeps on continental margins worldwide. It is understood that barite forms by the interaction of barium-rich and sulfate-free seeping fluids ...
