Abstract
A method of facilitating wet recovery of high density material from input wet incinerator bottom ash is disclosed. The method involves receiving the input wet incinerator bottom ash at a first density separator, separating by density from the input wet incinerator bottom ash, by the first density separator, first high density wet incinerator bottom ash and first low density wet incinerator bottom ash, causing the first low density wet incinerator bottom ash to flow to a second density separator, and separating by density from the first low density wet incinerator bottom ash, by the second density separator, second high density wet incinerator bottom ash and second low density incinerator bottom ash. Systems and apparatuses are also disclosed.

A method of facilitating wet recovery of high density material from input wet incinerator bottom ash, the method comprising:
- receiving the input wet incinerator bottom ash at a first density separator;
- separating by density from the input wet incinerator bottom ash, by the first density separator, first high density wet incinerator bottom ash and first low density wet incinerator bottom ash;
- causing the first low density wet incinerator bottom ash to flow to a second density separator;
- and
- separating by density from the first low density wet incinerator bottom ash, by the second density separator, second high density wet incinerator bottom ash and second low density wet incinerator bottom ash.
A system for facilitating wet recovery of high density material from input wet incinerator bottom ash, the system comprising:
- a first density separator configured to receive the input wet incinerator bottom ash and separate by density from the input wet incinerator bottom ash, first high density wet incinerator bottom ash and first low density wet incinerator bottom ash;
- and
- a second density separator configured to receive the first low density wet incinerator bottom ash and to separate by density from the first low density wet incinerator bottom ash, second high density wet incinerator bottom ash and second low density wet incinerator bottom ash.
