Direct Biohydrometallurgical Extraction of Iron from Ore ...
· A completely novel approach to iron extraction was investigated, based on reductive leaching of iron by anaerobic bacteria. Microorganisms were collected from an anaerobic bog where natural seepage of dissolved iron was observed. This mixed culture was used to reduce insoluble iron in a magnetite ore to the soluble ferrous (Fe{sup +2}) state. While dissolution rates were slow, ....
The Four Main Methods of Mining
· The solution gets to work and dissolves the ore before being pumped back into the surface to undergo processing. This method of mining allows for the extraction of salts and metals from an ore body without resorting to conventional mining methods such as underground mining. There are plenty of advantages to using insitu mining. It's the most ......

Types of Extraction | Scool, the revision website
Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ......
