information froth floatation process and fly ash separation

Removal of carbon constituents from hospital solid waste ...

A two–stage flotation process for HSWI fly ash treatment is proposed, which is efficient. Column flotation can simultaneously separate carbon constituents and PCDD/Fs from HSWI fly ash. The large amounts of NaCl and powder activated carbon in fly ash have effects on flotation process. The flotation process of fly ash is favorable to safe disposal of the final products at low cost.
