waste from froth flotation

  • Characteristics of an improved collector derived from a waste of coal

    In the present study, a collector reagent in the form of three distillation fractions from coal tar suitable for froth flotation was developed for the flotation of Indian coking coal fines. The developed tar fractions were compared with known reagent such as diesel, Ndodecane and kerosene oil. Tar fractions were found to be more

In froth flotation cells, the pulverized ore particles are fed downward via a pipe into a large tank where they are mixed vigorously with water, a reagent that promotes bubble attachment and compressed air or inert nitrogen gas. The result is a slurry mix of mineral laden bubbles
