Kinetics of barite reduction from refractory barite-sulphide ore
Refractory sulphide–barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships of lead, copper and zinc minerals with gangue minerals, it is not possible to enrich the ore using the conventional methods of ...

Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Abstract Hole U1601C, drilled during International Ocean Discovery Program (IODP) Expedition 399, reached a depth of 1,268 m below the seafloor (mbsf) in the Atlantis Massif (30°N, 42°W). This borehole represents only one of six boreholes that extends more than 700 m into oceanic rock, penetrating predominantly ultramafic lithologies, mostly composed ...
