 　眾所周知，中國(guo)的(de)(de)(de)經濟增(zeng)長依(yi)賴于石(shi)油(you)化(hua)(hua)工和(he)(he)其(qi)他能(neng)源的(de)(de)(de)支(zhi)持，特(te)別是自1980年代以來，能(neng)源對經濟發展(zhan)的(de)(de)(de)約束，導致的(de)(de)(de)高強度(du)消耗能(neng)源安全危機在我國(guo)越來越嚴重，此外，廢(fei)(fei)(fei)(fei)(fei)鐵回(hui)(hui)(hui)(hui)收(shou)(shou)相(xiang)關人員發現(xian)我國(guo)工業化(hua)(hua)的(de)(de)(de)加快，由燃煤排放的(de)(de)(de)污染問題逐(zhu)步深化(hua)(hua)。　　銅(tong)：無合金的(de)(de)(de)廢(fei)(fei)(fei)(fei)(fei)銅(tong)線(xian)(xian)，含有雜料，含銅(tong)量為(wei)96%（較小含量94%）。廢(fei)(fei)(fei)(fei)(fei)鋁回(hui)(hui)(hui)(hui)收(shou)(shou)不得(de)含有過(guo)(guo)分(fen)鉛化(hua)(hua)和(he)(he)錫化(hua)(hua)的(de)(de)(de)銅(tong)線(xian)(xian)、焊接(jie)過(guo)(guo)的(de)(de)(de)銅(tong)線(xian)(xian)、黃銅(tong)和(he)(he)青銅(tong)線(xian)(xian)、過(guo)(guo)多(duo)(duo)的(de)(de)(de)油(you)、廢(fei)(fei)(fei)(fei)(fei)鋼鐵和(he)(he)非金屬、脆(cui)的(de)(de)(de)過(guo)(guo)燒線(xian)(xian)、絕緣性銅(tong)線(xian)(xian)和(he)(he)過(guo)(guo)多(duo)(duo)的(de)(de)(de)細絲(si)線(xian)(xian)。需用(yong)(yong)適當方式清(qing)除塵垢。廢(fei)(fei)(fei)(fei)(fei)漆(qi)包線(xian)(xian) ：1級純漆(qi)包線(xian)(xian)，無雜質。2級：經過(guo)(guo)高溫脫漆(qi)，表面有氧化(hua)(hua)層，無雜質。廢(fei)(fei)(fei)(fei)(fei)銅(tong)回(hui)(hui)(hui)(hui)收(shou)(shou)很簡單：首先將(jiang)收(shou)(shou)集的(de)(de)(de)廢(fei)(fei)(fei)(fei)(fei)銅(tong)按污染程度(du)進行分(fen)揀，污染度(du)不高、未受污染的(de)(de)(de)廢(fei)(fei)(fei)(fei)(fei)銅(tong)和(he)(he)成分(fen)相(xiang)同的(de)(de)(de)銅(tong)合金回(hui)(hui)(hui)(hui)爐熔(rong)化(hua)(hua)，然(ran)后直接(jie)再利用(yong)(yong)；第二步將(jiang)相(xiang)互混合、成分(fen)復雜的(de)(de)(de)廢(fei)(fei)(fei)(fei)(fei)銅(tong)融化(hua)(hua)，在進行成分(fen)分(fen)離。經過(guo)(guo)這樣的(de)(de)(de)處理方法，銅(tong)的(de)(de)(de)物理、化(hua)(hua)學性質基本不變，可以得(de)到完全的(de)(de)(de)新生(sheng)。同時也可直接(jie)應用(yong)(yong)廢(fei)(fei)(fei)(fei)(fei)銅(tong)，直接(jie)應用(yong)(yong)廢(fei)(fei)(fei)(fei)(fei)銅(tong)的(de)(de)(de)優點有：成本低、污染小、回(hui)(hui)(hui)(hui)收(shou)(shou)率高等(deng)。

隨著通信(xin)事(shi)業的發展，人(ren)們對通信(xin)的需求越來越大，對光(guang)纜和(he)銅(tong)線的需求也將不(bu)斷增(zeng)加。鐵路電氣化對銅(tong)和(he)銅(tong)合金的需求量(liang)很(hen)大。再(zai)生銅(tong)企(qi)業的生產廢(fei)水主(zhu)要是冷卻水和(he)電解廢(fei)液，循環利用，基本上無需外部排放。廢(fei)鋼(gang)回收結構進一步優化廢(fei)鋼(gang)鐵是再(zai)生資源品種中(zhong)回收量(liang)占比高的品種。電爐煉(lian)鋼(gang)逐漸復產，鋼(gang)鐵企(qi)業不(bu)斷增(zeng)加廢(fei)鋼(gang)鐵的使用量(liang)，把多用廢(fei)鋼(gang)鐵作為節鐵增(zeng)鋼(gang)、節能減(jian)排的有力措施。使得廢(fei)鋼(gang)鐵進入大型鋼(gang)鐵企(qi)業的比例迅速(su)增(zeng)長達到85.1%。
