style="text-indent:25px">電池級(jí)碳酸鋰的清潔化生產(chǎn)方法包括如下步驟：（1）β-鋰輝石鋰精礦制備：選取富集天然鋰輝石精選礦1000kg置于回轉(zhuǎn)爐中，控制回轉(zhuǎn)爐內(nèi)溫度1100℃之下焙燒5小時(shí)即可制備得到β-鋰輝石鋰精礦；（2）硫酸鋰溶液制備：控制回轉(zhuǎn)爐溫度為95℃時(shí)，將β-鋰輝石鋰精礦粉碎過篩制成礦石粉，向礦石粉中加入過量25%硫酸溶液混合后轉(zhuǎn)入回轉(zhuǎn)爐在270℃下燒結(jié)5小時(shí)；（3）離子去除：向上述硫酸鋰溶液中加入100L濃度為1%的過氧化氫溶液將亞鐵離子氧化為鐵離子，然后加入30%的氫氧化鈉溶液至溶液pH為12，溶液中Mg和Fe形成氫氧化鎂和氫氧化鐵沉淀；（4）碳酸鋰的制備：將Na2CO3飽和溶液緩慢加入到溫度為90℃的上述步驟所得過濾后的Li2SO4溶液中，流加過程中持續(xù)測定溶液的pH值；隨著Na2CO3飽和溶液的加入，溶液的pH由12逐漸下降，當(dāng)混合溶液的pH為9.0，停止加入。保溫?cái)嚢?0min內(nèi)溶液pH無變化后過濾即可得到碳酸鋰沉淀；（5）電池級(jí)碳酸鋰的制備：將上述步驟得到的碳酸鋰沉淀在常溫下用2倍體積的純化水洗滌3次，70℃下烘干洗滌后樣品即可得到本發(fā)明電池級(jí)碳酸鋰成品，碳酸鋰的收率為85%。浙江碳酸鋰生產(chǎn)</p><p
