The invention belongs to the technical field of mineral processing treatment, and concretely discloses a dressing and smelting method for dephosphorization of scheelite preconcentrated concentrate. The dressing and smelting method for dephosphorization comprises the following steps: a scheelite preconcentrated concentrate slurry is heated, a modified fatty acid collector, an inhibitor A and an inhibitor B are sequentially added to the slurry, and the heated scheelite preconcentrated concentrate is subjected to one-stage roughing, three-stage scavenging and three-to-four-stage concentration toobtain low-phosphorus tungsten flotation concentrate and tungsten tailings; and the low-phosphorus tungsten flotation concentrate is leached with hydrochloric acid to obtain leaching residues which are final scheelite concentrate. The dressing and smelting method provided by the invention has the advantages of effectiveness in reduction of the phosphorus content of the scheelite concentrate, stable process is stable, and small amount of the acid for acid leaching.
