FLY ASH DISPOSAL - COSMOS

Generally, fly ash is a highly soluble and reactive material that contains significant quanti-ties of heavy metals (Zn, Pb, Cd, Cr, etc.). Often the heavy metals are present as anionic salts (chlorides and sulpha- tes), and alkaline anionic salts represent one of the main components of this waste (up to 25% of Cl in some samples). In this inorganic fraction, which is very variable in ...
