BIOX®, POX, and the Albion Process™ yield over 90% gold recoveryFurther work to enhance sulphide recoveries through oxidation ...

"Sulfide oxidation using molecular oxygen as the oxidant is one of the most challenging reactions in organic chemistry, and the development of new solid catalysts that can facilitate this type of ...

Metso’s Cu POX leaching utilizes high-temperature oxidation to convert sulfide sulfur into sulfate and sulfuric acid, ensuring efficient copper dissolution,” stated Petteri Pesonen, ...

This study focused on the MRB in Canada, a major contributor of freshwater, sediment, solutes, and organic carbon to the Arctic Ocean. It comprehensively analyzed hydrochemical data from 1960 to 2020 ...

Rusty red deposits in streambeds are distinctive signs of iron sulfide oxidation. Sulfides also acidify the water, which can accelerate weathering. Some alpine streams sampled were found have a pH ...

Exposure to air oxidizes the metal sulfides in bedrock, releasing the metals into groundwater, which flows into surface streams. Rusty red deposits in streambeds are distinctive signs of iron sulfide ...

The results showed that the silica-supported Cu-containing imidazolium ionic liquid exhibited the best catalytic performance for the diethyl sulfide oxidation with atmospheric oxygen, while the silica ...

4), then sulfide oxidation in the plume would set an upper limit on ROS production arising from the vent flux of reduced Fe and S species (Eq. 5) (6, 7). Eq. 5 shows the expected reaction chain ...
