The invention discloses a mineral processing method for improving the recovery rate of tungsten in tungsten fine slime. The mineral processing method is suitable for regrading reselected and recycled tungsten fine slime tailings, wherein the fineness of the tungsten fine slime is less than 0.1mm. The mineral processing method is characterized by comprising the following steps: concentrating and floating the reselected tungsten fine slime tailings; recovering sulphide ore; adding proper medicament into the flotation tailings; stirring and mixing size to agglomerate; firstly adding a dispersing agent, so as to lead various mineral grains in ore pulp to be uniformly distributed; adding proper collecting agent which acts and is attached on the surface of a fine-grained tungsten mineral; and finally adding specific flocculating agent; preferentially catching collecting agent molecules, and meanwhile, leading the fine-grained tungsten mineral to be agglomerated into an easily selected large particle mineral, and le
