RECOVERY OF PHOSPHORUS FROM DILUTE WASTE STREAMS |
摘要 |
<p>: RECOVERY OF PHOSPHORUS FROM DILUTE WASTE STREAMS Process for recovery of elemental phosphorus from phosphorus sludge produced in a phosphorus furnace by treating the sludge in a centrifugal separator and separating a fine dirt slimes fraction from a recovered heavy fraction containing the major portion of phosphorus; treating the slimes fraction in hydrocyclones not over one inch (25.4 mm) in diameter to separate two streams, a first phosphorus-poor stream containing particles smaller than 8-15 micrometers, and a second phosphorus-rich stream containing particles larger than 8-15 micrometers; recycling the second, phosphorus-rich stream to the centrifugal separator for phosphorus recovery, and discarding the first, phosphorus-poor stream.</p> |
