A process is disclosed for recovering purified glass from solid waste which includes a predominantly organic fraction and a predominantly inorganic fraction both of which contain glass particles. The predominantly inorganic fraction is further subdivided into a glass-rich fraction containing glass, inorganic, and organic constituents. The organic constituents are initially separated from the glass-rich fraction. The organics-free fraction is comminuted and screened to remove coarse particles greater than a first predetermined mesh size. The residue is classified to remove fine particles less than a second mesh size. The resultant mixture, after removal of coarse and fine particles, is subjected to froth flotation to form a float containing predominantly glass which is recovered for further use. |
