稀土生產工藝流程:我(wo)(wo)是(shi)做土(tu)(tu)建的(de)(de),現在(zai)建廠房(fang),廠房(fang)有(you)酸(suan)(suan)(suan)(suan)(suan)溶(rong)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、氯(lv)化(hua)釔車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、重型(xing)(xing)稀(xi)(xi)(xi)土(tu)(tu)萃取(qu)(qu)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、輕型(xing)(xing)稀(xi)(xi)(xi)土(tu)(tu)萃取(qu)(qu)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、沉淀車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、還(huan)有(you)倉庫制(zhi)水車(che)間(jian)(jian)(jian)(jian)(jian)(jian)。我(wo)(wo)想請問這(zhe)個生產(chan)工藝的(de)(de)流程是(shi)怎么樣(yang)的(de)(de)呢。請不要百(bai)度復制(zhi)粘貼,根據(ju)我(wo)(wo)這(zhe)些車(che)間(jian)(jian)(jian)(jian)(jian)(jian)來回答~我(wo)(wo)有(you)更好的(de)(de)答案一、酸(suan)(suan)(suan)(suan)(suan)溶(rong)車(che)間(jian)(jian)(jian)(jian)(jian)(jian),是(shi)把外面進(jin)來的(de)(de)料液(碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)稀(xi)(xi)(xi)土(tu)(tu)混合物(wu))放進(jin)酸(suan)(suan)(suan)(suan)(suan)里邊溶(rong)解(jie),現在(zai)一邊是(shi)設備(bei)里操作了,運行(xing)比較(jiao)(jiao)簡單,以前(qian)人工處(chu)理(li)調(diao)配(pei)時候(hou)很難的(de)(de)。二、分離車(che)間(jian)(jian)(jian)(jian)(jian)(jian),“重型(xing)(xing)稀(xi)(xi)(xi)土(tu)(tu)萃取(qu)(qu)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、輕型(xing)(xing)稀(xi)(xi)(xi)土(tu)(tu)萃取(qu)(qu)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、氯(lv)化(hua)釔車(che)間(jian)(jian)(jian)(jian)(jian)(jian)”主要是(shi)進(jin)行(xing)分離(根據(ju)在(zai)幾種酸(suan)(suan)(suan)(suan)(suan)的(de)(de)不同溶(rong)解(jie)度),把前(qian)面的(de)(de)碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)稀(xi)(xi)(xi)土(tu)(tu)分離成(cheng)單個元素(su)的(de)(de)硝酸(suan)(suan)(suan)(suan)(suan)、氯(lv)化(hua)物(wu)、碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)物(wu)。這(zhe)幾種也可(ke)以進(jin)行(xing)銷售(shou)。三、碳(tan)(tan)成(cheng)車(che)間(jian)(jian)(jian)(jian)(jian)(jian)、把氯(lv)化(hua)硝酸(suan)(suan)(suan)(suan)(suan)化(hua)物(wu)中加入碳(tan)(tan)銨,行(xing)程碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)稀(xi)(xi)(xi)土(tu)(tu)。這(zhe)個碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)稀(xi)(xi)(xi)土(tu)(tu)也可(ke)以進(jin)行(xing)銷售(shou),不過量比較(jiao)(jiao)小。四、隧道窯(yao)、滾窯(yao):這(zhe)兩套設備(bei)主要對碳(tan)(tan)酸(suan)(suan)(suan)(suan)(suan)稀(xi)(xi)(xi)。
