How metals are extracted from their ores? | AnswersDrive

Oct 02, 2019· The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a lessreactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.

extraction of metals introduction

Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.

Extracting Gold | HowStuffWorks

Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Groundwater Extraction – Physical Geology

Groundwater Extraction Except in areas where groundwater comes naturally to the surface at a spring (a place where the water table intersects the ground surface), we have to construct wells in order to extract it. If the water table is relatively close to the surface, a well can be dug by hand or with an excavator, but in most cases we need to use a drill to go down deep enough.

Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs onethird less. With a density of only grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal closepacked (hcp) crystalline structure, so that, like most metals of this structure, it lacks ductility when worked at lower temperatures.

How Is Iron Extracted From the Earth? |

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.
