The invention discloses a soil lamp drying mineral separation medium, a mineral separation machine and a mineral separation method. The mineral separation medium comprises a high-density magnetic core body; the mineral separation machine comprises a separation chamber; a medium particle and to-be-separation mineral inlet is formed in the top of the separation chamber; a vibrator or a vibrator and a driving mechanism for driving the separation chamber to rotate centrifugally are arranged on the bottom of the separation chamber; the outer side of the upper part of the separation chamber is provided with a light mineral discharging opening; the outer side of the lower part of the separation chamber is provided with a heavy mineral discharging opening; the light mineral discharging opening and the heavy mineral discharging opening are separately provided with a light mineral collection bin and a heavy mineral collection bin; a medium particle recycle system is arranged above each of the light mineral collection bin and the heavy mineral collection bin; the mineral separation method comprises the steps of mixing the to-be-separated mineral with the above mineral separation medium, feeding the above mixture into the mineral separation machine and the like. The soil lamp drying mineral separation medium, the mineral separation machine and the mineral separation method have the advantages that a separation technique is simple; separation effect meets practical requirement; production cost is low; the equipment is minimized; clean production is realized; and energy consumption is low.
