Froth flotation is the most widely used technique for the beneficiation of fine coals and minerals owing to its high separation selectivity (Darabi et al., 2020; Yu et al., 2017; Yang et al., 2021; Gao et al., 2023). Some researchers have also evaluated the oil recovery from oily sludge by froth flotation.

However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture …

Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means …
