The invention discloses a method for treating low-grade 
zinc oxide ores with high 
iron content and large argillization degree by a wet method. The method comprises the following steps of: 1, leaching directly, namely crushing the 
zinc oxide ores, performing ball-milling, and putting the 
zinc oxide ores and zinc electrolytic 
effluent into a reaction tank for reacting, wherein a 
leachate obtained after reaction is used for joint leaching, and leaching 
slag is conveyed to be washed in the next step; 2, performing joint leaching, performing leaching reaction of high-grade zinc oxide ores and a solution obtained after direct leaching is performed, wherein a neutral solution is used for purification, and the leaching 
slag is conveyed to a 
rotary kiln; 3, washing the 
slag, namely putting the slag leached directly and a weak acid solution into a reaction tank, stirring, reacting, allowing the solution to return for leaching directly, conveying the washed leaching slag to a dressing 
plant and separating to recover valuable metals such as lead and silver; and 4, reducing and volatilizing in the 
rotary kiln, namely mixing the leaching slag and coat uniformly, putting the mixture into the 
kiln for reacting to obtain zinc oxide 
smoke for recovering 
indium germanium and 
kiln slag for recovering iron and residual 
coal. By the method, 
metal ore resources can be utilized effectively, so the method has the advantages of low production cost, high 
leaching rate of zinc, high comprehensive utilization of the valuable metals and the like, the original production equipment and production flow can be utilized, and industrialization is easy to realize.
