Faugami XX is the XXth reference in the list of references. A slag sample from a lead refiner has been obtained and given to two analytical laboratories to determine the release of trace elements from the sample according to BS EN All in all it was concluded that a contact time of 24 hours might be preferable in a one-stage leaching test both with respect to fulfilling the equilibrium assumption and from a practical point of view.
Search all products by. Samples analysed by one laboratory passed waste acceptance criteria, leading it to be classified as an inert material; samples of the same material analysed by the other laboratory failed waste acceptance criteria and were classified as hazardous.
The purpose of this paper is to open a debate on designing a better defined standard leaching test and making current waste acceptance criteria more flexible.
