Bitcoin Mining vs. Gold Mining a Comparison

But mining does not simply cease until demand makes it profitable again, as is the case with gold mining. Instead, the Bitcoin protocol has a mechanism that ensures coins are always produced. When Bitcoin mining becomes unprofitable, and the hash rate consequently declines, the mining difficulty is automatically diminished.

Solvent Extraction an overview ScienceDirect Topics

Solvent extraction is generally not used to treat in organics (acids, bases, salts, heavy metals). Solvent extraction processes are not designed to treat particular compounds, and extraction efficiencies and processing rates are lower when there are high concentrations of indigenous organic compounds (humic and tannic acids in soil).

The Environmental Impact of Aluminum (And Why it's Still

Mining may be rough, but there is a silver lining (pun intended)! Almost 75% of all the aluminum ever produced in the US is still in use today. That's how well aluminum can be and is recycled! Aluminum is not only a great material because it's lightweight and conducts heat well, it can also be recycled indefinitely (if uncontaminated).

How Is Iron Extracted From the Earth? Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
