一(yi)、有人認為(wei)，銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)是(shi)我(wo)國(guo)長期缺乏的(de)(de)金屬，不存在過(guo)剩的(de)(de)問題，建設銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)冶(ye)煉(lian)能(neng)力(li)可以充分利用國(guo)外礦產(chan)(chan)資源，所以不應該局限于銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)冶(ye)煉(lian)項目。事實上(shang)，這(zhe)種觀點是(shi)片面的(de)(de)。中國(guo)確實缺銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。然而，銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)冶(ye)煉(lian)企業(ye)的(de)(de)建設本身(shen)并不是(shi)生產(chan)(chan)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，而是(shi)將銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)精礦加工成電解(jie)(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。因此(ci)，銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)冶(ye)煉(lian)項目的(de)(de)建設只能(neng)將中國(guo)對電解(jie)(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)需(xu)求轉變(bian)為(wei)對銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)精礦的(de)(de)需(xu)求，這(zhe)只會(hui)改變(bian)進口銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)產(chan)(chan)品的(de)(de)結構(gou)，與提(ti)高中國(guo)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)自給水平無關。
