Method of separating pulp containing magnetic constituents in a wet-magnetic, low-intensity concurrent separator and apparatus therefor

摘要

A method which pertains to the separation of pulp which contains magnetic constituents in a wet-magnetic, low-intensity separator of the concurrent type, in which a cylindrical, horizontally mounted rotatable drum coacts with non-rotating magnets disposed in the drum in a manner to convey magnetic constituents in contact with the drum surface to an outlet for magnetic concentrate, and in which method pulp which is depleted of magnetic constituents is separated as waste at a region remote from the concentrate outlet in a direction opposite to the direction in which the drum rotates. Additionally, pulp is delivered to the separator so as to bring the pulp into contact with the drum at or close to the highest level of the drum; water is delivered to the separator in the vicinity of the concentrate outlet such that water will flow in contact with the pulp constituents that accompany drum rotation; and water is removed from the drum together with the waste. A wet-magnetic separator is also set forth.
