The invention provides a separation method of tungsten-tin-bismuth-sulfur bulk concentrate. The method comprises the steps that firstly, tungsten-tin-bismuth-sulfur bulk concentrate is subjected to ore grinding and size mixing, then bismuth floating operation of one-time roughing, two-time concentration and two-time sweeping, sulfur floating operation of one-time roughing, two-time concentration and one-time sweeping and tungsten floating operation of one-time roughing, two-time concentration and one-time sweeping are sequentially carried out, and finally concentrate of tungsten, tin, bismuth, sulfur and the like is obtained through the technologies of low-intensity magnetic separation of flotation bismuth concentrate, table separation of flotation tungsten tailings and the like. According to the method, through collaborative operation of all reagents, the ore treatment amount is reduced, the number of devices is reduced, the technological process is simplified, the reagent cost is reduced, effective separati
