摘要： Decontamination of hardening salt residues is accomplished by treating the large pieces broken and slurried in water with an iron-II-chloride solution equivalent to the cyanide portion at a pH of 7-14, in the presence of at least the equivalent amount of alkali carbonate corresponding to the alkaline earth present, wherein the alkali carbonate does not exceed 30% based on the contaminated hardening salt residue.

摘要： A mass of finely divided material is confined in a chamber. Two rollers are arranged for rotation in the chamber in axial parallelism with one another and defined with each other a narrow longitudinally extending gap. At least one of the rollers has a circumferential wall composed of gas-permeable porous material. This one roller is hollow and arranged to communicate with a source of underpressure so that, as the roller rotates, the particulate material is attracted onto its outer surface forming a layer thereon which is subjected to substantial compaction when it passes through the gap between the two rollers. The rollers rotate in opposite direction. The compacted material is removed from the outer surface of the roller or rollers and subdivided into portions of desired size.
