2017年粗鋼產量(liang)8.3億(yi)(yi)噸(dun)，同(tong)(tong)比增加(jia)2336萬(wan)噸(dun)，增幅2.9%。共消耗廢(fei)鋼鐵1.48億(yi)(yi)噸(dun)，同(tong)(tong)比增加(jia)5781萬(wan)噸(dun)，增幅為64.2%。廢(fei)銅(tong)(tong)(tong)的回(hui)(hui)收利(li)用分為兩類，一類是(shi)新銅(tong)(tong)(tong)，主要(yao)是(shi)生產廢(fei)銅(tong)(tong)(tong)和冶煉銅(tong)(tong)(tong)的工業生產加(jia)工。另(ling)一種(zhong)是(shi)舊銅(tong)(tong)(tong)，已經流(liu)入銅(tong)(tong)(tong)后消費(fei)品中回(hui)(hui)收廢(fei)銅(tong)(tong)(tong)。隨著通信事業的發展(zhan)，人們對通信的需(xu)求(qiu)(qiu)越來越大，對光纜和銅(tong)(tong)(tong)線的需(xu)求(qiu)(qiu)也將(jiang)不斷增加(jia)。鐵路電氣化對銅(tong)(tong)(tong)和銅(tong)(tong)(tong)合金(jin)的需(xu)求(qiu)(qiu)量(liang)很大。

一般占(zhan)綜合能耗(hao)的60%。也就是說和鐵(tie)礦石相(xiang)比(bi)，用(yong)廢(fei)鋼(gang)(gang)(gang)直接煉鋼(gang)(gang)(gang)可(ke)節約(yue)能源(yuan)60%，其中每(mei)多用(yong)1噸(dun)(dun)廢(fei)鋼(gang)(gang)(gang)可(ke)少(shao)用(yong)1噸(dun)(dun)生鐵(tie)，可(ke)節約(yue)0.4噸(dun)(dun)焦炭或(huo)1噸(dun)(dun)左右的原煤。廢(fei)鋼(gang)(gang)(gang)鐵(tie)回(hui)收(shou)結構發生了較大變化，大型鋼(gang)(gang)(gang)鐵(tie)企業廢(fei)鋼(gang)(gang)(gang)鐵(tie)回(hui)收(shou)量同(tong)比(bi)增長64.2%，所占(zhan)廢(fei)鋼(gang)(gang)(gang)鐵(tie)回(hui)收(shou)總量比(bi)例(li)增至85.1%;其他(ta)企業回(hui)收(shou)量同(tong)比(bi)下降(jiang)57.5%，所占(zhan)廢(fei)鋼(gang)(gang)(gang)鐵(tie)回(hui)收(shou)總量比(bi)例(li)下降(jiang)至14.9%。如果我(wo)們在國際市(shi)場銅價非理性暴漲的情況下，一窩蜂到國外(wai)開發銅礦，廢(fei)銅回(hui)收(shou)勢必抬(tai)高基(ji)礎(chu)價格(ge)，付出沉重(zhong)的代價。

黃銅具(ju)有較強(qiang)的(de)耐(nai)磨(mo)性硬度(du)又比紫銅高，工(gong)地(di)鋼筋(jin)頭廢鋁(lv)回收價，所以(yi)通常用(yong)于(yu)制(zhi)(zhi)造閥門、水管(guan)、空調內外機(ji)連接管(guan)、散熱(re)器和(he)鎖具(ju)等或(huo)工(gong)廠企(qi)業(ye)產生的(de)廢黃銅邊(bian)角(jiao)料(liao)(liao)、機(ji)加工(gong)碎屑為主(zhu)。銅粉重要(yao)和(he)特色的(de)應用(yong)是(shi)(shi)粉末冶(ye)金(jin)領域(yu)(yu)。在(zai)此領域(yu)(yu)的(de)材(cai)(cai)料(liao)(liao)不(bu)是(shi)(shi)通過熔(rong)煉和(he)鑄造得到的(de)，例如(ru)：彌(mi)散強(qiang)化Cu-Al2O3用(yong)來強(qiang)化和(he)制(zhi)(zhi)造焊接電(dian)較(用(yong)于(yu)汽車(che)和(he)其它工(gong)業(ye)領域(yu)(yu))，用(yong)于(yu)電(dian)子部件的(de)熱(re)管(guan)理領域(yu)(yu)W-Cu和(he)Mo-Cu，此類材(cai)(cai)料(liao)(liao)需要(yao)控(kong)制(zhi)(zhi)其孔(kong)隙率(lv)。自潤滑軸承和(he)過濾器是(shi)(shi)粉末冶(ye)金(jin)領域(yu)(yu)典型的(de)應用(yong)。這(zhe)些材(cai)(cai)料(liao)(liao)要(yao)求控(kong)制(zhi)(zhi)適當的(de)孔(kong)隙率(lv)，以(yi)此含(han)(han)油量達到優良(liang)的(de)潤滑效果。廢鋁(lv)中經常含(han)(han)有油漆、油類、塑(su)料(liao)(liao)、橡膠等有機(ji)非金(jin)屬雜質。在(zai)回爐冶(ye)煉前，必(bi)須設法加以(yi)清除。對于(yu)導(dao)線(xian)類廢鋁(lv)，一般(ban)可(ke)采用(yong)機(ji)械研磨(mo)或(huo)剪切(qie)剝離(li)、加熱(re)剝離(li)、化學剝離(li)等措施去除。
