四、包括各種純銅(tong)(tong)(tong)(tong)廢(fei)(fei)(fei)(fei)料(liao)，首(shou)先是包含銅(tong)(tong)(tong)(tong)材加(jia)工(gong)廠和(he)銅(tong)(tong)(tong)(tong)加(jia)工(gong)制(zhi)造廠產生的(de)(de)純銅(tong)(tong)(tong)(tong)的(de)(de)邊角料(liao)、切(qie)頭、廢(fei)(fei)(fei)(fei)次(ci)(ci)材、半成(cheng)品、線材、廢(fei)(fei)(fei)(fei)品等；其(qi)(qi)次(ci)(ci)還(huan)有(you)報廢(fei)(fei)(fei)(fei)的(de)(de)純銅(tong)(tong)(tong)(tong)裸線和(he)銅(tong)(tong)(tong)(tong)管等其(qi)(qi)它純銅(tong)(tong)(tong)(tong)制(zhi)品，但不(bu)(bu)允許(xu)有(you)水垢、油(you)污、涂層等；再次(ci)(ci)廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)材中(zhong)不(bu)(bu)應(ying)含有(you)任何雜(za)質和(he)銅(tong)(tong)(tong)(tong)合金，也(ye)不(bu)(bu)許(xu)含有(you)毛絲、車(che)屑、磨(mo)屑和(he)厚度(du)小(xiao)于(yu)1mm的(de)(de)銅(tong)(tong)(tong)(tong)板。廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)回收原(yuan)本的(de)(de)廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)要(yao)經過(guo)融化(hua)(hua)、氧化(hua)(hua)、除渣和(he)還(huan)原(yuan)，才能夠生成(cheng)具有(you)一(yi)(yi)定(ding)純度(du)的(de)(de)銅(tong)(tong)(tong)(tong)水，進(jin)而(er)成(cheng)為(wei)(wei)有(you)利(li)用(yong)價值的(de)(de)銅(tong)(tong)(tong)(tong)桿。廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)的(de)(de)雜(za)質較多(duo)(duo)，要(yao)達到一(yi)(yi)定(ding)純度(du)必須反復氧化(hua)(hua)，每(mei)天一(yi)(yi)千噸的(de)(de)廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)一(yi)(yi)個(ge)工(gong)序就至(zhi)少(shao)需要(yao)6到8小(xiao)時(shi)，整個(ge)工(gong)序則需要(yao)20到22個(ge)小(xiao)時(shi)，廢(fei)(fei)(fei)(fei)銅(tong)(tong)(tong)(tong)回收多(duo)(duo)少(shao)一(yi)(yi)噸，如果雜(za)質過(guo)多(duo)(duo)還(huan)需要(yao)推遲時(shi)間。　　紫(zi)銅(tong)(tong)(tong)(tong)又名紅銅(tong)(tong)(tong)(tong)就，因其(qi)(qi)顏色為(wei)(wei)紫(zi)紅色而(er)得名，特性導電(dian)(dian)(dian)好(hao)、塑性好(hao)、導熱(re)(re)也(ye)好(hao)，但硬度(du)低(di)于(yu)黃銅(tong)(tong)(tong)(tong)，通常會用(yong)于(yu)發(fa)電(dian)(dian)(dian)機﹑母(mu)線﹑電(dian)(dian)(dian)纜﹑開關裝(zhuang)置﹑變壓(ya)器等電(dian)(dian)(dian)工(gong)器材和(he)熱(re)(re)交換(huan)器﹑管道﹑太(tai)陽能加(jia)熱(re)(re)裝(zhuang)置的(de)(de)平板集(ji)熱(re)(re)器等導熱(re)(re)器材。紫(zi)銅(tong)(tong)(tong)(tong)的(de)(de)鑒別方式與(yu)黃銅(tong)(tong)(tong)(tong)差不(bu)(bu)多(duo)(duo)，價格(ge)會在幾(ji)十塊錢一(yi)(yi)斤(jin)不(bu)(bu)等，根(gen)據摻雜(za)率與(yu)市場行情而(er)定(ding)，比(bi)如說化(hua)(hua)工(gong)單位處(chu)理的(de)(de)廢(fei)(fei)(fei)(fei)電(dian)(dian)(dian)纜，回收公司會根(gen)據廢(fei)(fei)(fei)(fei)紫(zi)銅(tong)(tong)(tong)(tong)價格(ge)，及電(dian)(dian)(dian)纜皮的(de)(de)重(zhong)量來進(jin)行打折。

銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)易與其(qi)它(ta)元素形(xing)(xing)成(cheng)(cheng)合(he)金，大量用(yong)(yong)來(lai)制造(zao)(zao)(zao)(zao)異(yi)型(xing)的(de)(de)(de)鍛件(jian)、鑄造(zao)(zao)(zao)(zao)件(jian)和(he)粉末冶金產品(pin)。銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)與鎳(nie)形(xing)(xing)成(cheng)(cheng)合(he)金具(ju)有抗海水腐蝕的(de)(de)(de)優良性能(neng)。錫(xi)可(ke)以(yi)提高(gao)固(gu)溶體中(zhong)(zhong)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)強(qiang)(qiang)度(du)(du)和(he)抗腐蝕性能(neng)。鋅和(he)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合(he)金，即黃銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)粉，被用(yong)(yong)于水管(guan)、鎖件(jian)、閥門(men)、管(guan)件(jian)。含有鎳(nie)、錫(xi)、鈦、鈹及(ji)(ji)鈷的(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合(he)金強(qiang)(qiang)度(du)(du)相(xiang)當(dang)于高(gao)強(qiang)(qiang)度(du)(du)鋼，而且具(ju)有高(gao)的(de)(de)(de)導電率和(he)導熱性能(neng)。銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)及(ji)(ji)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)鋅鋁合(he)金常被用(yong)(yong)于生(sheng)產片狀的(de)(de)(de)金粉。通過(guo)調整錫(xi)鎳(nie)成(cheng)(cheng)分，可(ke)以(yi)生(sheng)成(cheng)(cheng)特定(ding)的(de)(de)(de)顏色。黃銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)具(ju)有較(jiao)強(qiang)(qiang)的(de)(de)(de)耐磨性硬(ying)度(du)(du)又比紫銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)高(gao)，所以(yi)通常用(yong)(yong)于制造(zao)(zao)(zao)(zao)閥門(men)、水管(guan)、空調內外機(ji)連接(jie)管(guan)、散(san)熱器(qi)和(he)鎖具(ju)等或工(gong)廠企(qi)業產生(sheng)的(de)(de)(de)廢黃銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)邊(bian)角料、機(ji)加工(gong)碎屑為主。廢銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)供應中(zhong)(zhong)還有一類問題(ti)就是(shi)舊廢銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，主要是(shi)在(zai)使用(yong)(yong)時間(jian)之(zhi)(zhi)后被丟棄的(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)資源，通常我(wo)們會被進(jin)行回(hui)收(shou)商回(hui)收(shou)處理(li)之(zhi)(zhi)后，集(ji)中(zhong)(zhong)發展起(qi)來(lai)賣給造(zao)(zao)(zao)(zao)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)企(qi)業。回(hui)收(shou)商通常從廢舊建筑物設計(ji)以(yi)及(ji)(ji)中(zhong)(zhong)國(guo)交(jiao)通管(guan)理(li)工(gong)具(ju)中(zhong)(zhong)拆卸廢銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)資源是(shi)包(bao)著，一般這種(zhong)情(qing)況分析都可(ke)以(yi)被回(hui)收(shou)再(zai)生(sheng)。通常，三(san)分之(zhi)(zhi)一的(de)(de)(de)廢銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)是(shi)以(yi)精煉銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)形(xing)(xing)式形(xing)(xing)成(cheng)(cheng)的(de)(de)(de)，三(san)分之(zhi)(zhi)二的(de)(de)(de)廢銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)是(shi)以(yi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合(he)金的(de)(de)(de)形(xing)(xing)式重復利用(yong)(yong)的(de)(de)(de)。

隨著(zhu)通(tong)信(xin)事(shi)業(ye)的(de)(de)發展，人們對(dui)通(tong)信(xin)的(de)(de)需求越(yue)來越(yue)大，對(dui)光(guang)纜和(he)(he)銅線的(de)(de)需求也將不斷增加(jia)。鐵路電氣化對(dui)銅和(he)(he)銅合(he)金的(de)(de)需求量(liang)(liang)很大。再生(sheng)(sheng)銅企(qi)業(ye)的(de)(de)生(sheng)(sheng)產廢水(shui)主要是(shi)冷卻(que)水(shui)和(he)(he)電解廢液，循環利用，基本上(shang)無需外(wai)部(bu)排(pai)放。廢鋼(gang)(gang)(gang)回收(shou)結構進一步優化廢鋼(gang)(gang)(gang)鐵是(shi)再生(sheng)(sheng)資源(yuan)品種(zhong)中(zhong)回收(shou)量(liang)(liang)占比(bi)高的(de)(de)品種(zhong)。電爐煉鋼(gang)(gang)(gang)逐漸復產，鋼(gang)(gang)(gang)鐵企(qi)業(ye)不斷增加(jia)廢鋼(gang)(gang)(gang)鐵的(de)(de)使(shi)用量(liang)(liang)，把多用廢鋼(gang)(gang)(gang)鐵作為節(jie)鐵增鋼(gang)(gang)(gang)、節(jie)能減排(pai)的(de)(de)有力(li)措(cuo)施(shi)。使(shi)得(de)廢鋼(gang)(gang)(gang)鐵進入大型鋼(gang)(gang)(gang)鐵企(qi)業(ye)的(de)(de)比(bi)例迅速增長達(da)到85.1%。
