摘要： A magnetic separator apparatus for use in separating magnetic material from a mixture of at least magnetic material and a liquid includes an endless belt defining a channel. A portion of the endless belt is movable up an incline relative to horizontal through a separation zone. The endless belt includes an endless base section having a predetermined length and first and second sidewalls extending from the endless base section along the entire predetermined length thereof. The endless base section and the first and second sidewalls define the channel wherein the mixture is received. Further, the apparatus includes a ferromagnetic collection matrix positioned in the channel and one or more magnets positioned for generating a magnetic field in the separation zone. A method for use in separating magnetic material from a mixture using such an apparatus is also provided.

摘要： There is disclosed a process for scavenging iron from tailings produced by the flotation beneficiation of iron ore. This process includes the step of scavenging the flotation tailings using wet high-intensity magnetic separation (WHIMS). There is also disclosed a process for increasing the recovery of iron ore in a flotation beneficiation process. This iron ore recovery process includes the steps of feeding the magnetic concentrate produced by the scavenging process to a flotation system and then carrying out an additional flotation step.
