  • Method for processing and utilizing bypass dusts obtained during the production of cement
    Patent number: 8864904
    Abstract: In a method for processing and utilizing bypass dust obtained during the production of cement, it is proceeded as a) contacting the bypass dust with an aqueous phase and mixing the same to obtain a homogenous slurry, with water-soluble components of the bypass dust being dissolved in the aqueous phase, b) carrying out a solid-liquid separation to separate the solids contained in the slurry so that a brine is remaining, c) separating heavy metals present in the brine and precipitating calcium as poorly soluble calcium salts, e.g. CaCO3, to obtain a processed brine, and d) subjecting the processed brine to a fractional crystallization.
    Type: Grant
