Collection system for a wet drum magnetic separator

An improved collection system for a counter-rotating wet drum magnetic separator comprising:

• a tank for receiving a flow of a mixture of magnetic and non-magnetic particles in a feed port, and
• a collection system including:
• a rotating drum having a roughened collection surface disposed in the tank,
• an array of permanent magnetic elements disposed inside the drum arranged in a fixed position relative to an azimuthal section of the drum for establishing an azimuthal magnetic interaction region defined by a level of the mixture in the tank for attracting the magnetic particles to the roughened collection surface,
• a non-magnetic particle discharge port located on an opposite side of the tank as the flow of the mixture for removing the non-magnetic particles,
• a magnetic particle discharge port located outside the tank for receiving the magnetic particles, and
• a magnetic particle removal subsystem for removing magnetic particles trapped in the roughed collection surface and dispensing the magnetic particles to the magnetic particle discharge port.
