Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.

SURFACE MINING METHODS A surface mine is an openair excavation for removing minerals. Surface mining can be employed to extract metallic or nonmetallic mineral from any nearsurface deposit in any rock type. Nearsurface generally implies deposit less than 500 ft. the size of the deposit may range from a few tons to more than 100 million tons.

The Borax Method of Gold Extraction for SmallScale Miners

Methods . Gold capture, as well as the amount of mercury released into the environment, was analyzed for two amalgamation methods and the borax method. The Amalgamation Methods . Mercury is used in gold mining because of its ability to bind to gold to form an alloy which helps separate the precious metal from rock, sand and other material.
