The invention discloses a method for recovering zinc from willemite resources and belongs to the technical field of mineral processing. The method comprises the following steps that (1) raw ore is crushed to form willemite of preset fineness; (2) a sodium agent is added into the willemite, pelletizing is carried out after sufficient mixing, the mixture is subjected to sodium salt roasting under the oxidizing atmosphere, and a sodium salt roasted product is obtained after cooling is carried out; and (3) the sodium salt roasted product is crushed and immersed in water, so that zinc leachate is obtained. According to the method, zinc is extracted through a mineral phase reconstitution-water immersion method, a zinc silicate mineral phase is converted to zinc oxide through sodium salt roastingof the willemite, the conversion effect is good, and subsequent water immersion and extraction are easy; the sodium agent adopts sodium carbonate and is low in cost and easy to obtain; and compared with a pyrogenic process carbon reduction, no coke needs to be added as a reduction agent, the energy consumption is low, the reaction rate is high, and the zinc leaching rate is 90% or above. According to the method, the zinc extraction effect is good, the leaching cost is low, selectivity is good, no silica gel is produced compared with acid-process leaching, and subsequent leaching, filtering and separation are easy.
