Gold mining is the process of mining of gold or gold ores from the ground.

Peter Ward Yeah, every single cell in us can produce minute quantities of hydrogen sulfide in great crises.

China dominates the global market simply because it has fairly abundant rare earth ores close to the surface.

Faced with severe supply constraints, Asian economies are increasingly tapping other continents fossil fuels, mineral ores, and timber.

The abundances of less volatile compounds such as ammonia, water, and hydrogen sulfide in the deep atmosphere are poorly known.

And what you're seeing here is a cloud of densely packed, hydrogen sulfide rich water coming out of a volcanic axis on the sea floor.

Rare earth ores in southern China all except for those in Inner Mongolia contain radioactive substances that pose significant threats to human health and the environment.

Indeed, rare earth elements are rare only in the sense that they are distributed in small quantities and must be extracted from ores, a time consuming process.

You're in an accident. You've got two choices you're going to die, or you're going to take the hydrogen sulfide and, say, 75 percent of you is saved, mentally.

Unlike most satellites in the outer Solar System, which are mostly composed of water ice, Io is primarily composed of silicate rock surrounding a molten iron or iron sulfide core.

Am I understanding you right, that what you're saying here is that we have in our own bodies a biochemical response to hydrogen sulfide that in your mind proves that there have been past mass extinctions due to climate change?

And so we thought, like in a game of musical chairs, might we be able to give a person some hydrogen sulfide, and might it be able to occupy that place like in a game of musical chairs where oxygen might bind?

The majority of potential bidders are deterred not only by the investment amount, but also by the complexity of the project extensive in mine exploration of reserves and methods for working with complex ores are required, Kommersant's sources in the industry explain.

And in an enormous 40 page paper in German he says, at one point my wife is German and she translated it for me and at one point he says, ganz widerlich Geruch, an absolutely repulsive smell, which is good. Reminiscent of hydrogen sulfide.

We draw from stocks of non renewable natural resources (for example, oil and metal ores), and we deteriorate or modify the quality of other resources (for example, water and arable land) by imposing on them a rhythm of exploitation superior to their capacity for regeneration.

We draw from stocks of non renewable natural resources (for example, oil and metal ores), and we deteriorate or modify the quality of other resources (for example, water and arable land) by imposing on them a rhythm of exploitation superior to their capacity for regeneration. In fact, the exploitation of non renewable resources frees the speed of economic growth from that of ecological renewal, aggravating the deterioration of the biosphere, including irreversible climate changes.
