It is a type of process for purification of ores. Lighter impurities are repeated from denser metal by air movement such that metal settle at bottom

The froth flotation process is a method used to separate minerals from their ore using chemical reagents and air bubbles. It relies on the differences in the surface properties of the minerals being separated, such as their hydrophobicity (ability to repel water) or hydrophilicity (ability to attract water).

Physical properties of metals, on the other hand, refer to the characteristics of metals that can be observed or measured without changing the chemical composition of the material. Some important physical properties of metals include electrical conductivity, thermal conductivity, density, melting point, and malleability.

In the context of froth flotation, the physical properties of metals can affect their flotation behavior. For example, metals with high hydrophobicity tend to attach to air bubbles more readily, making them easier to separate from the ore. Similarly, metals with high density may settle faster in the flotation tank, facilitating their collection.

Understanding the physical properties of metals is crucial in designing an effective froth flotation process, as it helps in selecting the appropriate chemicals and operating conditions to achieve efficient separation of minerals from their ore.
