The theory dealing with the propagation of phosphorus sludges in elemental phosphorus production is generally well known, but it has long been felt that an investigation should be made in order to devise a suitable process whereby it may become possible to effect a separation of phosphorus. It is perhaps unfortunate that while the development of the electric furnace process continued, it sometimes overshadowed the importance of recovering additional amounts of phosphorus by relatively simple and inexpensive means since this is considered vital to the economics of elemental phosphorus production. At the present time, there is no economically feasible process by which elemental phosphorus can be separated from phosphorus-bearing sludges. The published literature is scant and thus the conclusion is drawn that very little work has been done on this subject.

It was with this problem in mind that the research described in the thesis was undertaken. It is the author's hope that the results, by making the problem amenable to relatively simple treatment, will allow fuller use of a practical and continuous method of separating elemental phosphorus from phosphorus-bearing sludges, and encourage any further studies in the future.
