  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.Онлайн-запрос

  • Flotation of sodium carbonate and sodium bicarbonate salts

    Aug 01, 2002· Flotation of sodium bicarbonate is so strong, especially with DAH that even 15–20 min after flotation, the particle loaded froth remained stabilized as the froth product. Flotation results at the temperatures considered are given in Table 4.
