Which Metal Cannot Be Extracted By Smelting?

Solution : (a) Aluminium cannot be extracted by the smelting process because :
(i) `Al`is highly electropositive element and has strong affinity for oxygen. Hence, `Al_(2) O_(3)` is a very stable compound and is not reduced by carbon.

Which metals can be extracted by smelting?

Lead, iron and zinc can be extracted by smelting process .

Which metals Cannot be extracted?

The metal that cannot be extracted by hydrometallurgy is zinc. This is because to extract zinc more reactive metals are required.

Can copper be extracted by smelting?

Smelting is the process of extracting base metal by applying heat to the ore: Some of the metals which can be extracted by the smelting process are: Silver. Copper.

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.

What is smelting with example?

In the smelting process a metal that is combined with oxygen—for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping as carbon monoxide or carbon dioxide.

What is a copper smelter?

Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches.

Which metal Cannot be extracted by aluminium?

As sodium (alkali metal) is more reactive than Al so it cannot be extracted from Na2O by using Al as a reducing agent.

Which metal is not extracted by the process of electrolysis?

Copper is not extracted by electrolysis. Rest other elements such as sodium, aluminium, magnesium are extracted by electrolysis.

Which of the following metals is not extracted by leaching?

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”.

How do you extract Aluminium?

Extraction of aluminium
Aluminium ore is called bauxite . The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis. The ions in the aluminium oxide must be free to move so that electricity can pass through it.

How is nickel extracted?

It is extracted from its ores trough a conventional roasting method which removes the moisture from the ore. Next the nickel oxide is removed by reduction furnace which also greatly reduces the chemical bound water. Resulting in a 75% pure form of nickel.

How do you smelt iron?

This is how iron has been smelted by blacksmiths for hundreds of years:

1. Gather iron ore. Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves.
2. Build the furnace.
3. Prep the reducing agent.
4. Charge the furnace.
5. Heating the iron ore and charcoal.
6. Finishing touches.

Which metals Cannot be extracted by heating their ores with carbon?

Some metals can be extracted by heating with carbon such as zinc, tin, lead, copper and iron from their corresponding oxides. Metals above zinc in the reactivity series are too reactive to be extracted by heat- ing with carbon or carbon monoxide gas.

Can aluminium be extracted using carbon?

Electrolysis is used to extract aluminium from its ore as aluminium is more reactive than carbon therefore cannot be extracted by carbon. Any metal in the reactivity series above carbon must be extracted using electrolysis as it to too reactive.

Which metal Cannot be extracted by heating metal oxide with carbon?

Iron cannot be extracted by reduction with carbon.

Who invented smelting?

The development of iron smelting was traditionally attributed to the Hittites of Anatolia of the Late Bronze Age. It was believed that they maintained a monopoly on iron working, and that their empire had been based on that advantage.

What is called smelting?

Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.

How do you smelt gold?

Smelting gold is accomplished by using high pressure, heat and various chemicals to breakdown the ore and melt the gold to separate it from the impurities. The gold must be heated to an excess of 1046 degrees Celsius or 2150 degrees Fahrenheit.

How is Aluminium smelted?

Aluminum production first begins with smelters extracting aluminum from bauxite (sedimentary rock) during a two-step aluminum smelting process. The Bayer process separates alumina from bauxite. Also known as aluminum oxide, alumina then undergoes the Hall-Héroult process, producing pure aluminum.

Can you smelt magnetite?

Highlights. Magnetite iron ores were routinely smelted during the second millennium CE. Most contain more than 2% TiO₂ and cannot be used as ore for modern blast furnaces. Bloomery iron smelting technology can use iron ores with up to 25%.
