What is added to quicklime to make slacked lime?
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2
Why is limestone added as a raw material to the furnace?
Limestone is added as a raw material to the furnace primarily to act as a flux in the iron and steel-making process. When heated, it decomposes to produce lime, which helps to remove impurities such as silica and alumina by forming a slag that can be easily separated from the molten metal. This not only enhances the quality of the final product but also protects the furnace lining from damage. Additionally, the use of limestone can help improve the efficiency of the smelting process.
Is smelting an expensive process?
Smelting can be expensive due to the energy and equipment required. The cost can vary depending on factors such as the type of ore being processed and the method of smelting used. Additionally, environmental regulations and labor costs can also impact the overall expense of the smelting process.
Why the small amount of coke is required in the smelting process and how slag formed during smelting?
In the smelting process, a small amount of coke is required primarily as a reducing agent to convert metal oxides into their metallic forms. The carbon in coke reacts with oxygen in the metal oxides, producing carbon dioxide and facilitating the extraction of the metal. Slag forms as a byproduct when impurities in the ore, such as silica and alumina, combine with fluxes (often added to the furnace) during the heating process. This molten mixture floats on top of the metal and can be removed, helping to purify the final metal product.
How does the process of smelting work?
Smelting is the process of extracting metal from its ore by heating it in a furnace with a reducing agent such as coke. This process removes impurities and leaves behind the pure metal, which can then be further refined or used in manufacturing. Temperature control and the addition of fluxes are important in achieving the desired outcome in smelting.
How does smelting occur or what is involved in the process of smelting?
in a type of furnace cant remember which one or the name
What is added to quicklime to make slacked lime?

What is smelting waste called?
Smelting waste is often referred to as slag. Slag is the byproduct generated during the smelting process when impurities are separated from the metal ore.

Does gold burn off in smelting process?
No.
What gas is released in the process of smelting?
Carbon dioxide is released during the smelting process as a result of chemical reactions with carbon-based materials used in the process.
Is smelting an expensive process?
Smelting can be expensive due to the energy and equipment required. The cost can vary depending on factors such as the type of ore being processed and the method of smelting used. Additionally, environmental regulations and labor costs can also impact the overall expense of the smelting process.
How do you get slaked lime from seashells?
the only way to get slaked lime is by burning the sea shells in a lime kiln then by adding cold water, this chemical reaction is by burning the carbon off from the calcium then replaced by oxygen atoms, this process will make the seashell lighter , when cold water is added this process will break down the seashell, then turn into hydrated lime.
How does stainless steel resist corrosion?
It has a quantity of Chromium (usually around 10%) added during the smelting process. The Chromium forms a 'film' on the surface - preventing rusting.
Is the name of the process of removing iron from ore called smelting?
No, the process of removing iron from ore is called extracting or refining. Smelting is a different process that involves heating the ore to extract metal from it.
What is the process that ore into useful metals called?
Smelting
When did Abraham Darby invent coke smelting process?
Abranham Darby invented coke smelting, in the year of 1709. KalaBadala :)
