Ways of extracting metal from its ores

The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization

    Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction

    Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides

    Answer (1 of 2): It is a general rule that the more reactive a metal is the more difficult the extraction for example comparing gold and sodium. With gold, you simply pick the metal from its ore but with sodium, you have to crush the ore, concentrate it then carry out electolysis under some very

    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 extract from its compound. Electrolysis. Electrolysis is the most powerful extraction method
