一种制备一水合疏酸锰的方法 技术领域
本发明涉及一种制备一水合硫酸锰的方法。
背景技术
锂离子汽车动力电池所用的 MnS04 · H20原料对化学指标要求较严格, 需 要加以精制处理, 现有技术主要是碳酸化精制工艺或氨法精制工艺, 这些方 法的收率低, 分离效率不明显, 成本也较高。
发明内容
本发明提供一种制备一水合硫酸锰的方法, 该方法利用 MnS04与 BaS或 SrS的定量反应,将 Mn转化为 MnS ,再加入浓石充酸溶解 MnS ,生成 MnS04溶液, 经过蒸发烘干, 从而定量回收了 MnS04溶液中的 Mn。
本发明的主要贡献在于反应的思路, 所用的试剂及工艺设备均为现有技 术中所常用的, 并不是本发明的关键, 因此筒略描述。
该方法主要包括以下步骤:
1 )将硫酸锰配制成溶液, 加入等摩尔的 BaS或 SrS溶液充分反应, 固液 分离, 洗涤固相;
其中, 步骤 1 ) 中原料硫酸钡可以选择任意的硫酸锰, 如申请号为 20091 0179944. 9的专利申请中的烟气脱硫的方法产生的硫酸锰, 如申请号为 20091 0157921. 8的专利申请中的硫化锶或硫化钡与二氧化锰矿反应, 再与硫 酸反应所得的硫酸锰, 也可以使用市售的硫酸锰; 将该硫酸锰配制成一定浓 度的溶液, 一般选 1 0_450g/L较合适, 原因是浓度太大会造成夹带损失, 浓 度太小会造成后面的蒸发步骤能耗加大。 硫酸锰与硫化钡或硫化锶等摩尔反 应主要是为了使反应充分, 节约成本, 如果硫化物不足, 锰的回收率会下降, 硫化物过量则会带来硫化物的损失; 待反应完成后, 固相中主要成分为硫酸 钡和硫化锰, 还存在一些杂质离子, 洗涤固相步骤主要目的在于分离所得固 相中的可溶性杂质离子, 如 K+,Na+等。 优选地, 所述步骤 1 )中洗涤固相步骤利用温度为 50-70 °C热水洗涤, 洗 涤时间为 1-2小时, 可以洗涤多次。
2 )在步骤 1 ) 固液分离所得的固相中加入去离子水打浆, 用浓^ £酸溶解 该浆料, 固液分离;
其中, 溶液中 MnS04进入下步净化处理程序, 而固相则主要为 BaS04, 经 洗涤烘干可得硫酸钡产品。
优选地, 所述步骤 2 ) 中加入浓石克酸后产生的 H2S气体可以用 BaS或 SrS 溶液吸收处理, 生成的 Sr ( HS ) 2或 Ba ( HS ) 2, 可以作为还原性硫化物与 Mn02 反应。
3 )将步骤 2 ) 固液分离所得 MnS04溶液, 加入适量过氧化氢, 升温煮沸, 调节 pH为 5-6 , 精密过滤, 溶液蒸发结晶并烘干获得 MnS04 · H20产品。
其中, 在步骤 3 ) 中加入过氧化氢是为了除去铁等杂质, 另一方面还可 以氧化少量的石克化物, 同时不引入其他杂质。 例如锰的碱性化合物, Mn (OH) 2或 MnC03等。
优选地, 所述步骤 3 )在加入过氧化氢之前, 可以先调节 pH为 1-2 , 此 步仍然优选 Mn (0H) 2或 MnC03进行; 此次调节是为了防止酸度过大时, 加入过 氧化氢后, 中和时则需要加入较多的 Mn (0H) 2或 Mn2C03, 这样带入的铁等杂质 的量就会增多, 从而影响产品的品质。
优选地, 所述步骤 3 ) 中精密过滤步骤可以利用直径为 0. 24-0. 45μηι的 滤月莫,通过压滤机实现。
本发明涉及的主要化学反应包括:
MnS04 + BaS → BaS04 + MnS
MnS04 + SrS → SrS04 + MnS
MnS + H2S04→ MnS04 + H2S t
本发明的主要工艺流程如图 1所示。
本发明通过 MnS04与 BaS或 SrS的反应定量地回收了 MnS04溶液中的 Mn, 提高了 MnS04精制过程中锰的回收率。本发明的制备方法工艺收率高,分离效 率明显, 成本也比较低。
