High-Temperature and High-Pressure Phase Transition of Natural Barite Investigated by Raman Spectroscopy and Electrical Conductivity

Frontiers in Earth Science, 2022
We investigated the structural, vibrational, and electrical transport properties for natural barite under the conditions of 298–873 K and 1.5–35.0 GPa using a diamond anvil cell by virtue of Raman spectroscopy and electrical conductivity measurements ...

Morphology of Barite Synthesized by In-Situ Mixing of Na₂SO₄ and BaCl₂ Solutions at 200 °C

Crystals, 2021
Barite is an abundant sulfate mineral in nature. Especially, the variety of morphologies of barite is often driven by the mixing of Ba-bearing hydrothermal fluid and sulfate-bearing seawater around hydrothermal chimneys. In order to better understand the

Origin of Hydrothermal Barite in Polymetallic Veins and Carbonate-Hosted Deposits of the Cyclades Continental Back Arc

, 2023
Polymetallic veins and breccias and carbonate-replacement ore deposits in the Cyclades continental back arc, Greece, formed from a range of fluid and metal sources strongly influenced by the dynamics of the late Mesozoic-Cenozoic Hellenic subduction ...

BARITE PRECIPITATION FOR TREATMENT OF MINE WATERS WITH HIGH SULPHATE CONCENTRATIONS [PDF]

, 2023
One of the commonly used methods for removing sulphates from mine waters is the precipitation. The classical approach for the treatment of acid mine drainage (AMD) rich in heavy metals and sulphates at about of 2000 mg/L is based on using Ba added in ...

Toward an Improved Understanding of the Marine Barium Cycle and the Application of Marine Barite as a Paleoproductivity Proxy

Minerals, 2020
Marine barite (BaSO4) is a relatively ubiquitous, though minor, component of ocean sediments. Modern studies of the accumulation of barite in ocean sediments have demonstrated a robust correlation between barite accumulation rates and carbon export to ...
