To determine the mineral separation process for the non-magnetic material precision sorting problem based on the first-order buoyancy of a magnetic fluid, this study examines the stress of non-magnetic objects immersed in a magnetic fluid by changing the distance between the permanent magnet and the magnetic fluid when the permanent magnet is used as a magnetic source. A structural model of automatic flotation separation is then designed. In the design plan, the lifting stroke of the electric scissor lift platform used for the lifting of the magnetic source was 100 mm; different magnetic field strengths can be provided to the magnetic liquid by lifting the magnetic source. Accordingly, a Cartesian robot and an end effector are designed to separate the non-magnetic materials to salvage and separate non-magnetic objects suspended at different heights. Then, the ANSYS Maxwell software is used to conduct two-dimensional and three-dimensional simulations of the design situation. The approximately calculated first-order buoyancy of the non-magnetic objects provides a certain basis for the design of the lifting platform’s load-bearing capacity. The results show that the suspension height of the specified non-magnetic cylinder in the magnetic liquid is 60–70 mm from the bottom of the container according to the simulation data calculation, which provides a theoretical basis for the design of a flotation separation device. A cylindrical permanent magnet with a height of 30 mm and a radius of 80 mm is used to provide the magnetic field. Converting the first-order buoyancy of the non-permeable magnet into density, the density range of the non-permeable magnet that can be floated using this design is approximately 1.65 × 103‒ 6.66 × 103 kg/m3.
