Live Chat2020313Methods of extraction Many metals are found in the Earths 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
Live Chat2013116There are alternative methods of agitation that are just as effective but much simpler to put into practice. In addition economics become increasingly important and one of the most important objectives is to improve the efficiency of extraction so that less solvent is needed and evaporation requirements for concentrated products are reduced.
Live ChatHow Is Quart Extracted Extraction. Quart is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quart. The reason for this is that although quart is known for its hardness it damages easily if it is suddenly exposed to a change in temperature such as that caused by a
