廢(fei)為寶”重要的(de)(de)，就是還原后銅(tong)(tong)(tong)(tong)的(de)(de)純度，每天(tian)還要取樣(yang)來分析其中(zhong)的(de)(de)氧含(han)量(liang)等是否達標(biao)。以前再(zai)(zai)生銅(tong)(tong)(tong)(tong)對廢(fei)銅(tong)(tong)(tong)(tong)的(de)(de)要求(qiu)比(bi)較高(gao)，需要按照(zhao)一定比(bi)例搭配原材料(liao)才能實(shi)(shi)施，經過實(shi)(shi)驗(yan)后，只要是廢(fei)銅(tong)(tong)(tong)(tong)就可以進(jin)行再(zai)(zai)生，技術上取得(de)了進(jin)步(bu)。在(zai)以前，金屬銅(tong)(tong)(tong)(tong)都是從(cong)銅(tong)(tong)(tong)(tong)礦(kuang)石(shi)中(zhong)提煉，礦(kuang)山開采及(ji)冶煉過程容易(yi)污染破壞(huai)環境。而原料(liao)全部(bu)使用(yong)(yong)廢(fei)銅(tong)(tong)(tong)(tong)料(liao)，廢(fei)銅(tong)(tong)(tong)(tong)回(hui)收廠家公司，不含(han)硫等排放(fang)物(wu)(wu)，符(fu)合(he)節能、低污染、規模化(hua)再(zai)(zai)生資(zi)源回(hui)收與綜合(he)利用(yong)(yong)的(de)(de)產業(ye)政策(ce)方向。廢(fei)銅(tong)(tong)(tong)(tong)廢(fei)鋁回(hui)收“廢(fei)銅(tong)(tong)(tong)(tong)”也可以變廢(fei)為寶，節能減(jian)排。關于再(zai)(zai)利用(yong)(yong)的(de)(de)問題：因廢(fei)銅(tong)(tong)(tong)(tong)包(bao)含(han)范圍(wei)大，我們(men)可將其按回(hui)收利用(yong)(yong)的(de)(de)簡易(yi)程度分類，如：表(biao)面(mian)干凈，無(wu)雜物(wu)(wu)黏(nian)著(zhu)物(wu)(wu)為一類；表(biao)面(mian)及(ji)內部(bu)混(hun)有雜物(wu)(wu)為第(di)(di)二類；廢(fei)舊無(wu)法使用(yong)(yong)的(de)(de)純銅(tong)(tong)(tong)(tong)電(dian)器開關、零件(jian)(jian)等為第(di)(di)三(san)類等。也可根據實(shi)(shi)際情況具體分類。我們(men)稱(cheng)含(han)銅(tong)(tong)(tong)(tong)量(liang)高(gao)于99%的(de)(de)廢(fei)銅(tong)(tong)(tong)(tong)為1號銅(tong)(tong)(tong)(tong)，可直接融化(hua)和再(zai)(zai)利用(yong)(yong)。稱(cheng)含(han)銅(tong)(tong)(tong)(tong)量(liang)低于945%的(de)(de)銅(tong)(tong)(tong)(tong)為2號銅(tong)(tong)(tong)(tong)，必須重新(xin)融化(hua)使用(yong)(yong)。　在(zai)粉(fen)末冶金領域(yu)，用(yong)(yong)純銅(tong)(tong)(tong)(tong)粉(fen)生產電(dian)子和導(dao)熱(re)零部(bu)件(jian)(jian)。含(han)有錫、鋅、鎳、或者鐵的(de)(de)銅(tong)(tong)(tong)(tong)合(he)金被廣泛用(yong)(yong)于汽車、草地公園設備、工具和電(dian)子工業(ye)。銅(tong)(tong)(tong)(tong)粉(fen)使用(yong)(yong)在(zai)自潤滑軸承上，另外是Fe-Cu預混(hun)合(he)，化(hua)學工業(ye)領域(yu)的(de)(de)滲析和摩(mo)擦材料(liao)部(bu)件(jian)(jian)。
