Biooxidation BioMineWiki
In bioleaching the desired metal is leached from the ore. In biooxidation or biobeneficiation the undesired metals and other compounds are leached "away" from the ore. 1) Two types of sulfide ores. To the left sulfur (yellow) is bound to a metal (green), for example copper. To the right sulfur (yellow) is bound to a metal (blue), for example iron.

Ore Wikipedia
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined to extract the valuable element or elements. The ore grade, or concentration of an ore mineral or metal, as well as its form of .

Iron Mining Process Minnesota Iron
The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. Pellets The concentrate (the wet taconite powder) is rolled with clay inside large rotating cylinders.

Separating Iron and gold from rock. by Elsa Huber on Prezi
There are many ways to extract iron ore from rock. Iron is magnetic so you could use a method that involves magnets, and it is also heavier than a lot of substances, so you could use a shaker and see which pieces weigh more. However, the way that we thought to separate iron ore

Gold Extraction / Mining |
Extraction of Gold using the Borax Process. The low melting point thus enables gold to be extracted using a cost effective, low power heat sources to bring about melting. The gold sinks to the bottom of the crucible, whereas other rock material such as silicon, quartz, ore or generally all oxides rise to the top.

Extracting Gold | HowStuffWorks
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
