smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.
What does the term smelting mean Class 8?
Smelting is the process of reducing the roasted metallic oxide to a metal. In this process, impurities are removed by the addition of appropriate flux. It reduces the oxide ore to metals in its molten state.

How is metal smelted?
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.

What type of clothing is at a large market in Europe?
Cotton and Silk had a large market in Europe. Different varieties of Indian textiles like Chintz, Cossaes or Khassa and Bandanna were sold in European markets.
Why did the production of iron and steel decline in the mid 19th century?
Import of steel ingots from Britain gradually led to decline or the Indian iron smelting industry in the nineteenth century. The new forest laws were also responsible for this because finding wood and charcoal was becoming more difficult. New forest laws also restricted the smelters’ access to iron ore mines.
What’s the difference between melting and smelting?
Both processes involve heating a substance into a higher temperature. The main difference between melting and smelting is that melting converts a solid substance into a liquid whereas smelting converts an ore to its purest form.
What are the steps to smelting?
This is how iron has been smelted by blacksmiths for hundreds of years:
- Gather iron ore. Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves.
- Build the furnace.
- Prep the reducing agent.
- Charge the furnace.
- Heating the iron ore and charcoal.
- Finishing touches.
What equipment is used for smelting?

What is a furnace made of?
Today’s modern furnace uses stainless steel, aluminized steel, aluminum, brass, copper, and fiberglass. Stainless steel is used in the heat exchangers for corrosion resistance. Aluminized steel is used to construct the frame, blowers, and burners. Brass is used for valves, and copper in the electrical wiring.
What were the problems faced by the Indian textile industry in India during its early years?
It found difficult to complete with the cheap textiles imported from Britain. In most countries, government supported industrialisation by imposing heavy duties on imports.
