Abstract
The present invention relates to a method of concentrating and recovering precious metals from waste mobile phone PCBs and spent automotive catalysts using waste nonferrous slag, in which precious metals such as gold, silver, platinum, palladium or rhodium can be concentrated and recovered by simultaneously treating different industrial wastes, including waste nonferrous slag, waste mobile phone PCBs and spent automotive catalysts, and industrial waste can be recycled as resources. According to the present invention, it is possible to maximize the utilization ratio of precious metal resources that totally depend on the import in terms of the domestic situation of a poor-natural resources country. In addition, the industrial waste can widely be utilized for the recovery of precious metals in the fields of household appliance recycling and electronic part manufacture, and the recycling of industrial by-products discharged in the field of non-ferrous refinery.
