摘要： Sodium metaborate is recovered from a boron-containing first feed solution by extraction of the first feed solution with a 1,3-diol, followed by re-extraction with a solution of an alkali metal hydroxide. Boric acid is recovered from a boron-containing second feed solution by extraction of the second feed solution with a water-insoluble aromatic polyol, followed by re-extraction with mineral acid. The boric acid and sodium metaborate are reacted to form sodium tetraborate. By exchanging sodium ions in the polyol extract with potassium ions, the potassium salts of the mineral acid may be recovered from the polyol as a by-product.
摘要翻译：通过用1,3-二醇萃取第一进料溶液，然后用碱金属氢氧化物溶液重新萃取，从含硼第一进料溶液中回收偏硼酸钠。通过用不溶于水的芳族多元醇萃取第二进料溶液，然后用无机酸重新萃取，从含硼的第二进料溶液中回收硼酸。硼酸和偏硼酸钠反应形成四硼酸钠。通过用钾离子交换多元醇提取物中的钠离子，无机酸的钾盐可以作为副产物从多元醇中回收。

摘要： A process for preparing manganese sulfate solutions having reduced concentrations of potassium impurity is disclosed wherein a digestion mixture of a reduced manganese ore, a source of water soluble aluminum ions, a source of water soluble ferric ions and an aqueous acid solution is prepared, having a solution pH ranging from about 0.5 to about 3.5. The mixture is then digested at a temperature sufficient to produce a mixed digestion product comprising a liquid phase of a manganese sulfate solution and a solid phase of digested ore residue and a particulate complex salt by-product. The liquid phase of manganese sulfate solution is then recovered from the mixed digestion product. An additional feature of this process involves conducting the digestion of the digestion mixture in the presence of at least one complex salt of the general formula:MFe.sub.n Al.sub.3-n (SO.sub.4).sub.2 (OH).sub.6where M is Na.sup.+, K.sup.+ or NH.sub.4.sup.+ and n is a number ranging from about 1 to about 3.
摘要翻译：公开了一种制备具有降低的钾杂质浓度的硫酸锰溶液的方法，其中制备了还原锰矿石，水溶性铝离子源，水溶性铁离子源和酸水溶液的消化混合物，其具有溶液pH范围为约0.5至约3.5。然后将混合物在足以产生包含硫酸锰溶液的液相和消化的矿石残余物的固相和颗粒状复合盐副产物的混合消化产物的温度下消化。然后从混合消化产物中回收硫酸锰溶液的液相。该方法的另外特征包括在存在至少一种通式为MFenAl 3-n（SO 4）2（OH）6）的络盐存在下进行消化混合物，其中M为Na +，K +或NH 4 +，n为数字范围从1到3。
