銅有多少種

分三(san)種類型：1、自(zi)然銅(tong)(tong)(tong)------銅(tong)(tong)(tong)含量(liang)(liang)在(zai)99％以(yi)(yi)上，但儲量(liang)(liang)極少; 氧化(hua)銅(tong)(tong)(tong)礦(kuang)-----為數(shu)也不多(duo)； 硫化(hua)銅(tong)(tong)(tong)礦(kuang)-----含銅(tong)(tong)(tong)量(liang)(liang)極低，一般在(zai)2--3%左(zuo)右，世界上80%以(yi)(yi)上的(de)銅(tong)(tong)(tong)是從硫化(hua)銅(tong)(tong)(tong)礦(kuang)精(jing)(jing)煉(lian)(lian)(lian)(lian)出來(lai)的(de)。 2、按生(sheng)產(chan)過程分類： 銅(tong)(tong)(tong)精(jing)(jing)礦(kuang)----冶(ye)煉(lian)(lian)(lian)(lian)之(zhi)前選出的(de)含銅(tong)(tong)(tong)量(liang)(liang)較高的(de)礦(kuang)石； 粗銅(tong)(tong)(tong)------銅(tong)(tong)(tong)精(jing)(jing)礦(kuang)冶(ye)煉(lian)(lian)(lian)(lian)后的(de)產(chan)品，含銅(tong)(tong)(tong)量(liang)(liang)在(zai)95－98％； 純(chun)(chun)銅(tong)(tong)(tong)------火煉(lian)(lian)(lian)(lian)或電解(jie)之(zhi)后含量(liang)(liang)達(da)99％以(yi)(yi)上的(de)銅(tong)(tong)(tong)。火煉(lian)(lian)(lian)(lian)可(ke)得99－99.9％的(de)純(chun)(chun)銅(tong)(tong)(tong)，電解(jie)可(ke)以(yi)(yi)使銅(tong)(tong)(tong)的(de)純(chun)(chun)度達(da)到99.95-99.99％。 3、按主要合金(jin)成份分類： 黃銅(tong)(tong)(tong)-----銅(tong)(tong)(tong)鋅(xin)合金(jin)； 青銅(tong)(tong)(tong)-----銅(tong)(tong)(tong)錫合金(jin)等(除了(le)鋅(xin)鎳外，加入其他元(yuan)素(su)的(de)合金(jin)均稱青銅(tong)(tong)(tong))； 白銅(tong)(tong)(tong)-----銅(tong)(tong)(tong)鈷鎳合金(jin)。
