froth flotation is a process using air bubbles to separate materials based on their relative affinity to water bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed froth flotation has been for more than a century in mining operations to separate valuable materials from excavated ores

froth flotation is a physico-chemical separation process. separation is principally based on differences in surface hydrophobicity. however, particle size and density have a significant impact. initial flotation patent and application was developed for graphite by the bessel brothers 1877. similar to graphite, coal is naturally hydrophobic
