Abstract

The invention discloses a method for dissolving and purifying precious metal from electronic waste, relates to the technical field of comprehensive utilization of industrial solid waste. Aiming at the problem of poor utilization efficiency of the existing industrial solid waste,the following scheme is provided; the method for dissolving and purifying the precious metal from the electronic waste comprises the following steps of: mixing the electronic waste containing the precious metal with acid liquor; decomposing the electronic waste through acid liquor to obtain decomposition liquid containing precious metal; filtering and cleaning the obtained decomposition liquid; removing water-soluble impurities in the decomposition liquid to obtain precious metal powder; putting the obtained precious metal powder into corresponding drying equipment; and drying the precious metal powder through the drying equipment. According to the method for dissolving and purifying the precious metal from the electronic waste, the precious metal of the electronic waste in the industrial solid waste can be rapidly and efficiently purified and collected, the purification method is simple, processing equipment used for purification is convenient to use, and then the extraction and storage progress of the precious metal is effectively improved, and the recovery efficiency is high.

Description

Technical field [0001] The present invention relates to industrial solid waste utilization technology, and in particular relates to a method for purifying a noble metal is dissolved from electronic scrap. Background technique [0002] With the development of industrial production, the increasing number of industrial wastes. Because of the large number of industrial waste, a wide range of complex composition, process quite difficult. [0003] Most existing industrial solid waste to dumps and landfill disposal methods, although it may be disposed of industrial solid waste, industrial solid waste, but since there is often a certain amount of a noble metal, as the industrial solid waste after stockpiling and disposal to landfill and other methods, industrial solid waste in the precious metals will be lost in the process, wasting a lot of resources, for which we propose a dissolution purification from electronic waste the method of precious metals. Inventive content [0004] One prop...
