Claim One:
1. A method for recycling automobile and electronic waste metal, comprising: A) separating the automobile and electronic waste to obtain a plurality of separated metal pieces, washing and/or breaking and/or selecting the separated metal pieces to obtain several piles of homogenous metal pieces; B) performing full-elemental analysis on the homogenous metal pieces in each pile; C) quantitatively combining weights of the different piles of homogenous metal pieces and obtaining different combinations of weights, and performing weighted averaging of the combinations of weights to calculate the full-elemental weighted average according to the different combinations of weights D) comparing the full-elemental weighted average of different combinations of weights with different alloy grades, so as to find one or more closest types of alloy grades and to set the alloy grades as target alloy grades; and E) performing further processing on metal pieces in combinations of weights corresponding to the target alloy grades, and producing alloy products or raw materials for metallurgy of the target alloy grades.
