The intelligent magnetic microfluidic concentrator comprises a sorting system consisting of an ore feeding chute (1), an overflow chute (2), an overflow tank (4), a sorting tank (5), and a magnetic system (6), the overflow tank (4) is disposed at an upper portion of the sorting tank (5), the ore feeding chute (1) is disposed at the top of the overflow tank (4), the ore feeding chute (1) feeds an ore slurry to the upper portion of the sorting tank (5) circumferentially along an inner wall of the sorting tank (5), and the tailings overflow out upward from the overflow tank (4) disposed centrally and located at the upper half portion of the sorting tank (5). The magnetic flotation sorting technique and the magnetic fluid-control separation technique are combined and cooperate to accomplish the function of accurate sorting, and an influence of unstable in-field ore feeding and water supply on the sorting effect is improved by intelligently regulating the water supply, the discharge of ore concentrate, and the magnetic field, whereby the precise separation of magnetic particles and impurities is achieved, a high extent of grade upgrading is accomplished while ensuring a high recovery rate, the amount of water consumed by the equipment is reduced, and the purpose of automation the equipment is achieved. A magnetic microfluidic concentrator and a complete set of beneficiation equipment are also provided. 15
