METHOD OF SEPARATION OF PHOSPHORUS FROM A MIXTURE WITH OTHER SOLID SUBSTANCES Russian patent published in 2005 - IPC

FIELD: methods of separation of element phosphorus from phosphorus-containing slimes.

SUBSTANCE: the invention is pertaining to the method of separation of element phosphorus from phosphorus-containing slimes by melting the phosphorus in a slime in the reticular container. The method of the phosphorus separation provides for usage of a separator containing: a tank for holding a liquid, a container located inside the tank and at least part of which is made out of a reticular material, through which the indicated fluid medium can pass, and a melted solid matter can flow through it and a non-melted solid material cannot pass through it. The cells of the indicated net have a diameter approximately equal to 0.2-0.6 cm. The container is at least partially dipped in the pointed liquid, and any part of the container, which has been not dipped in liquid, is in an inert atmosphere. Besides use a heater for heating the liquid above the fusion point of phosphorus. The method includes the following stages: placement of the indicated mixture in the pointed container of the separator and heating of the liquid to the temperature above 44.1°C for a melting of phosphorus and its flowing out through the pointed net from the pointed container. The container may represent a cylinder rotating around its shaft located at an angle α to a horizontal and equal approximately to 0-5°, and-or on an internal side of the cylinder there are a screw type vanes for transportation of not melted solid material along the pointed cylinder at its rotation. The technical result is a capability to separate phosphorus from mixtures.

EFFECT: the invention ensures a capability to separate phosphorus from mixtures.
