METHOD FOR REUTILIZING WASTE ORIGINATING IN THE FORM OF DUST OR SLUDGE

As a process for recycling heavy-metal-containing special waste, produced as dust or mud, by binding in a ceramic clay product, it is proposed that the clay mineral-containing starting material used is overburden clay or waste material from coal mining, which has been ground to a particle size of at...

Zusammenfassung:	As a process for recycling heavy-metal-containing special waste, produced as dust or mud, by binding in a ceramic clay product, it is proposed that the clay mineral-containing starting material used is overburden clay or waste material from coal mining, which has been ground to a particle size of at least 80 % less than 0.5 mm, in a solid fraction in packing material of 20 to 90 % by weight, calculated with the exclusion of any coal content that may be present, and that from this an extender for a packing material in mining is produced having a particle size of at least 95 % less than 32 mm.
