Which metals are not extracted by electrolysis?

The oxides of less reactive metals, such as iron, form less stable oxides and other compounds. Relatively little energy is needed to reduce them to extract the metal….Reactivity and extraction method.

Which metal Cannot be extracted from its ore?

We can see that among the given elements, zinc (Zn), tin (Sn), and lead (Pb) are less reactive than carbon (C) whereas aluminum (Al) is more reactive than carbon. Therefore option (B) Al metal cannot be extracted by the carbon reduction process.

Which of the following metal is not extracted?

The process leaching is generally used for the extraction of aluminum ore, silver ore, gold ore and low grade copper ores too. But mercury as we all know is soluble at room temperature so it can go through the process of leaching. So, the correct answer is “Option B”.

Which metals can be extracted from its ore by electrolysis?

Reactivity and extraction method

Is zinc extracted by electrolysis?

Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells.

Which metal can be extracted from its ore?

Extraction using carbon Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced.

Which of the following metals Cannot be obtained by reduction of its metal oxide by aluminium?

Among the metals Cr,Fe,Mn,Ti,Ba, and Mg, the one that cannot be obtained by reduction of metal oxide by aluminium is. Mg reacts with C to form Magnesium carbide.

Which of the following metals is extracted using a silica lined converter?

Copper matte is put in a silica-lined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO3).

How metals are extracted from ores?

Metal is extracted from the crushed ore by one of two major methods: smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore. Electrolysis separates metal from ore by using acid and electricity.

Which metal can be extracted from bauxite ore?

Aluminium
Aluminium can be extracted from bauxite. Bauxite is an ore of aluminium and the compound is aluminium oxide (Al2O3. 2H2O).

Which metal Cannot be extracted from their ores by heating the metal oxide with carbon?

Iron cannot be extracted by reduction with carbon. Many metals are extracted from their ores by heating the metal oxide with carbon.
