Residual lime sludge or black sludge is treated by admixing a drying agent in the form of soot in a mixing ratio, counted in units of volume, of 1:2-1:4, suitably 1:3, the soot absorbing liquid from the residual lime sludge and forming with the sludge a dry, particulate and/or granular mixed product. |
