Method for treating low-grade zinc oxide ores by wet method

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 o...

Zusammenfassung:	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 val
