MINING

The ore is transported from the mine by a combination of rear-dump off-highway trucks, belt conveyors, aerial tramways and railways. Ore for export is dried in rotary kilns to reduce the moisture content, while that for local processing is used as mined. About a half of the bauxite mined is shipped unprocessed to the United States.

What is Gold Extraction? (with pictures)

Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is typically mined first, though this is not always necessary, and then subjected

Pyrite

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Minnesota mining history

Minnesota's iron ore was actually discovered while miners were on their way to seek gold. Since their aim was gold, the iron was ignored. As it turned out, the iron would become more valuable to northern Minnesota than the gold. Iron ore was discovered on the three iron ranges at different times.
