Carbon Reduction Method Chemistry Tutorial
The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1 , Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no energy to extract the metal.

Types of Extraction | S-cool, 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
Magnesium hydroxide precipitates, while calcium hydroxide remains in solution. Magnesium hydroxide is filtered off and on heating readily forms the pure the oxide. Conversion to magnesium chloride is achieved by heating the oxide, mixed with carbon, in a stream of chlorine at a high temperature in an electric furnace (Figure 1).
Ion-exchange resin - Wikipedia
In this appliion, ion-exchange resins are used to remove poisonous (e.g. copper) and hazardous metal (e.g. lead or cadmium) ions from solution, replacing them with more innocuous ions, such as sodium and potassium.Few ion-exchange resins remove chlorine or organic contaminants from water – this is usually done by using an activated charcoal filter mixed in with the resin.
Lunar Geology: Minerals on the Moon - PERMANENT
Calcium oxides and calcium silies are not only useful for ceramics, but pure calcium metal is an excellent electrical conductor. Calcium metal is not used as a conductor on Earth simply because calcium burns spontaneously when it comes in contact with oxygen (much like the pure magnesium metal in camera flashbulbs).
5 Different Types of Extraction (and Experiments) – …
It is an extraction method used to extract the most reactive metals from an ore; a compound of a metal mixed with impurities. It is the most expensive since a lot of electricity is used. Electrolysis deals with the addition of electrons into the metal ions at a hode terminal(the negative electrode).
