| Abstract: | The processes of the purification after dewaxing or deoiling waste clay from refinery and of the purification afterdewaxed or deoiled waste clay were studied. The activity and content of montmorillonite from purified waste clay werecharacterized by CEC and M.B. values. The experimental results show the optimum procedure of waste clay purification. |
