| Abstract: | The research relates to regent-absent dressing of clayey diatomite based on the mineral constitution of the diatomite. The experimental results show qualified concentrates of diatomite can be obtained from the clayey diatomite by combined process of regent-absent dressing and acid leaching. The quality concentrates contain SiO 2 of 89.87%, Al 2O 3 3.00%, Fe 2O 3 0.54%. The technology can consume only a small amount of acid. |
