Difference Between Fusion and Casting
Main difference
The main difference between the terms smelt and smelt is that smelting is the conversion of a solid substance into a liquid and smelting is the conversion of the ore to its purest form.
Melt vs. Melt
Melting is the process of converting or changing the state of a substance from a solid to a liquid form. Smelting is the process of extracting metals from ores in their purest form. Melting is a simple process of heating the substance to the melting point where it starts to liquefy. Smelting is a process that involves calories and chemicals to melt ore into pure metals. When melting, substances are put under great pressure to melt them, a combination of heat and pressure is also used. A body can also be melted at a lower temperature. With the combination of heat and pressure, in smelting, chemicals such as reducing agents are used to wash other elements from the ores into slag (waste) or gases leaving only the metal. Melting is primarily done to mold an item or substance into a particular shape for use in various ways. Smelting is done for base metals such as copper, iron, silver, and gold. In simple terms, melting is the process by which a substance changes from its solid phase to its liquid phase. Smelting is a process by which metal is extracted from its ore at temperatures beyond the melting point. The melting of a pure substance occurs at a fixed temperature called the melting point. Melting involves a step known as roasting that is done at very high temperatures. So, melting occurs at the melting point of a (pure) substance and melting takes place at temperatures beyond the melting point of a mineral.

What is melting?
Melting is a simple process of heating the substance to its melting point where it begins to liquefy. It is the process of converting or changing the state of a substance from solid to liquid. When melting, substances are subjected to great pressure and heat to melt them. Melting is primarily done to mold an item or substance into a particular shape for use in various ways. Fusion is also known as fusion. It is a phase transition process. The internal energy of the substance increases during fusion. In the process of fusion, the tight packing of molecules or ions begins to loosen. A solid substance has a more orderly and compact structure than a liquid. Merging makes it a less ordered structure. When a solid begins to melt, its volume increases because the liquid does not have a tight packing like the solid. Therefore, the density decreases. But there are also some exceptions, such as the melting of ice to form water. In this case, the density of ice cubes is less than that of water. The melting point is a temperature point where the solid begins to change shape to a liquid. The melting point of an impure substance is not fixed, since it melts at a different temperature. The melting of an impure substance varies depending on the type and amount of impurities present. In the process of melting a substance or an element, the viscosity also changes when it is in the liquid state. The melting point of an impure substance is not fixed, since it melts at a different temperature. The melting of an impure substance varies depending on the type and amount of impurities present.

What is foundry?
Smelting is the process of extracting metals from ores in their purest form. It involves heat and chemicals to melt the ore into pure metals. There are two requirements of the casting process, heat treatment and reducing agent. Smelting obtains a metal at temperatures beyond the melting point of its ore. An ore is a natural material in solid form, from which a valuable metal or ore is profitably extracted. Smelting involves the conversion of the ore into its purest form. The third process removes the metal from the ore that is mined. Very strong heat is applied to separate the pure metal from other impurities. Common applications for smelting include the production of iron, silver, copper, and other metals from their ores. The casting process has two main steps which are roasting and reduction. Roasting involves heating the ore in the presence of a large amount of air or oxygen. Reduction involves the environment removing oxygen atoms from the raw material. Carbon is the most common reducing agent. The ores are mostly impure, so a cleaning agent like limestone is used to remove the impurities as waste and get the pure metal. Smelting is a very important and basic process to obtain metals in their pure form.

Key differences
- Melting is the process in which a substance changes from its solid phase to its liquid phase, while melting is the process by which a metal is obtained from its ore at temperatures beyond the melting point.
- Melting occurs at the melting point of a pure substance, on the other hand, melting takes place at temperatures beyond the melting point of a mineral.
- Melting is primarily done to mold an item or substance into a particular shape to be used in various ways, while melting is done for base metals such as copper, iron, silver, and gold.
- Fusion is a spontaneous process in reverse. Casting is not a spontaneous process.
- Fusion produces liquid from a solid substance, while fusion gives a simple compound or pure element from an impure mineral.
