Removal of Elemental Phosphorus from Electric Furnace Sludge Using Froth Flotation.
For Reference Only At Bureau Libraries :114 pages
Electrothermal production of elemental phosphorus (p4) generates substantial amounts of highly toxic phossy water and sludges. Because of the high phosphorus content and lack of a reliable processing technology, large tonnages of these hazardous wastes are being accumulated from current and past operations. The sludges are stored in ponds or in special containment vessels at various locations around the country despite the serious environmental problems they pose. Under a 3-year research subcontract agreement of the U.S. Bureau of Mines, Grant Number G1195132 to the mineral industry waste treatment and recovery generic center and the Alabama Mineral Resources Research Institute of the University of Alabama, the removal of elemental phosphorus from electric furnace sludge using froth flotation was investigated. The objective of this project was to develop a flotation process to remove and/or recover p4 from the waste sludge and render the sludge residue nontoxic. An appendix to the paper contains the text of three related papers.
