This metal has a low density and is extracted by electrolysis?
Aluminium, this is the correct answer if you are completing the AQA Science homework sheet. If not, titanium is also a low density metal and is extracted by electrolysis.
What is meant by - smelting?
Smelting is the process which ore goes through so that a metal can be extracted from it. It involves heating the rock to very high temperatures. Copper, for instance, can be extracted at temperatures of about 1200 °C.Actually, smelting is a process when a metal which is more reactive than copper needs to be extracted. For example, zinc is more reactive than copper so it has to be extracted smelting. It can be extracted by heating its ore with charcoal aka smelting.--different person
What are th two methods of extraction metals from the ore?
Mining techniques can be divided into two common excavation types: surface mining (above ground) and subsurface (underground) mining. sometimes subsurface mining is also called deep mining like in my text book p.s i am in 8th grade
How would you extract sodium?
Sodium is not generally "extracted from its ore" to be recovered and used. Most of the sodium we consume is used in the form of sodium compounds, like table salt (NaCl, or sodium chloride). Recovering the pure metal takes some doing as it is highly reactive. Sodium metal reacts with the moisture in air, and must be stored below something like kerosene to keep it isolated and in its elemental form. To extract sodium metal, we generally use electrolysis on molten salt (sodium chloride) in what is called a Downs cell. The metal is recovered, cooled and "packaged" to keep it from reacting with anything prior to use. A link can be found below to check facts and learn more.
What is sacrificial coating?
When a more reactive metal sacrifices itself for a less reactive metal to prevent the lesser reactive metal from rusting. :-)
Why sodium was not discovered until 1807?
Sodium is a very highly reactive metal, sodium has to be extracted by electrolysis from its rock salt, the process of electrolysis had to be invented.
How was lithium the element extracted?
Lithium is extracted as the molten metal by a process of electrolysis.

How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
Is aluminium found as metal?
Yea But in a compound Al2O3 Bauxite Removed or extracted by electrolysis
Where sodium is obtained?
Sodium cannot be obtained as the pure metal and it is extracted by electrolysis of a sodium salt.
Which process is generally used in extracting magnesium in metallurgy?
Fused salt electrolysis is generally used in extracting magnesium in metallurgy. In the extraction of metal, magnesium is usually extracted by the electrolysis of fused anhydrous MgCl2 because of its reactive nature. Another process uses silicon to reduce magnesium oxide.
How does metal come from the ground?
through the process of smelting ore Ore is mined from the ground in rock or particle form and then processed using many different techniques. The most basic form of smelting involves the utilization of the different melting points of metal, allowing a smelter to heat ore to a desired temperature and melt out the desired product. This metal is then refined.
Which metal oxides will not react with carbon?
Metals which are above Carbon in the reactivity series, eg. Magnesium. These metals need to be extracted by electrolysis.
What problems are caused when extracting metals from their ores by displacement?
Using Electrolysis: is the most powerful extraction method. But it takes a lot of electricity and that makes it expensive. Hence, electrolysis is only used for the most reactive metals.The method of extracting metal from its ore depends upon how reactive the metal is. The more ractive the metal, the more difficult and expensive it is to seperate from its ore.

Why was sodium not extracted until 1807 explain fully?
The main extraction method for sodium is electrolysis. This extraction method was not discovered until 1807.
