Sulfide in a sentence

Hydrogen sulfide emissions A severe anoxic event at the end of the Permian would have allowed sulfate-reducing bacteria to thrive, causing the production of large amounts of hydrogen sulfide in the anoxic ocean.

In similar fashion, hemoglobin also has competitive binding affinity for cyanide (CN − ), sulfur monoxide (SO), nitric oxide (NO), and sulfide (S 2− ), including hydrogen sulfide (H 2 S).

In these organisms, hemoglobins may carry oxygen, or they may act to transport and regulate other small molecules and ions such as carbon dioxide, nitric oxide, hydrogen sulfide and sulfide.

Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as iron sulfide.

Traditionally these were used for carrying out the first step: formation of two liquids, one an oxide slag containing most of the impurity elements, and the other a sulfide matte containing the valuable metal sulfide and some impurities.

When water level drops and sulfide minerals are exposed to air, arsenic trapped in sulfide minerals can be released into water.

As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade.

It is also not unusual to see a high-grade volcanic massive sulfide deposit support a strip ratio greater than 5:1.

Outcrops of sericite altered intrusive rock with molybdenite bearing quartz veinlets have been identified in the area as have gold and silver bearing quartz-sulfide veins.

The East Zone conductor is the largest and highest amplitude in the entire survey, with near-surface conductors consistently correlated with intense copper sulfide mineralization at surface.

The lower section of the interval contains very strong mineralization with 1-5% visual sulfide and localized breccias containing up to 30% chalcocite.

The new dangers found in the FAU study add to the risks already associated with sargassum, chiefly the risk to people with respiratory problems stemming from the release of hydrogen sulfide, which gives the sargassum it’s unpleasant odor.

Then low residual concentrations of hydrogen sulfide can cause irritation to the eyes, nose, and throat.

The Sheeted Vein zone consists of northwest-striking parallel quartz-sulfide veins that dip to the east, with widths of at least 7 m. The veins host semi-massive to massive galena, green sphalerite, and tetrahedrite masses along a quartz stockwork.

We're not aware of data from anyone that demonstrated these fundamental challenges of lithium-metal dendrite formation in sulfide-based systems has been addressed at room temperature and modest pressures.

Workers exposed to methane, ethane, carbon dioxide, hydrogen sulfide or other hydrocarbon components from drilling and refining can experience respiratory problems, headaches, dizziness and insomnia.

Sulfide in the soil was oxidized and became sulfate, which is no longer a solid phase, allowing cadmium to easily filter through and escape into the plant easily.

The in the ocean form when salt water and hydrogen sulfide combine and become denser than the rest of the water.

The rhyolite unit is overlain by a sphalerite-chalcopyrite massive sulfide body up to 100m thick (on the section).

The solid sulfide electrolyte has the world’s highest reported sodium ion conductivity – roughly 10 times higher than is required for commercial use.
