Abstract
As part of the total metallurgical system to recover metals from secondary resources, the Bureau of Mines conducted froth flotation research, using cationic reagents to recover glass from urban refuse. Batch flotation tests showed that high-quality cullet can be obtained from glass-rich aggregates derived from municipal incinerator residues and unburned refuse. This was confirmed by pilot plant operations treating 350 pounds of flotation feed per hour. Aggregates containing 85 to 90 percent glass were wet-ground to minus 20 mesh, deslimed in two stages, and fed to flotation cells. The glass was selectively floated using an amine collector, usually in an amount under 0.2 Pound per ton of solids in the feed. The glass concentrates from the rougher cells were cleaned by refloating two or three times. Over 90 percent of the glass in the deslimed feed was recovered in the cleaned concentrates.
