  Although U.S. Pat. No. 8,182,784 teaches the recovery of potassium chloride from schoenite end liquor (SEL) using dipicrylamine as extractant, and consequently simplifies the recovery of sulphate of potash (SOP) from kainite mixed salt employing the scheme disclosed in U.S. Pat. No. 7,041,268, the hazards associated with this extractant have thwarted practical utilization of the invention. Many other extractants for potash recovery have been disclosed in the prior art but none has been found suitable so far for practical exploitation. It is disclosed herein that the bitartrate ion, and particularly L-bitartrate, precipitates out potassium bitartrate very efficiently from SEL with ca. 90% utilization of the extractant. In contrast, recovery of potassium bi-tartrate from sea bittern directly is relatively much lower. It is further disclosed that this precipitate can be treated with magnesium hydroxide and magnesium chloride to throw out magnesium tartrate with ca. 90% recovery while yielding a nearly saturated solution of potassium chloride which can be utilized for the reaction with schoenite to obtain SOP. It is further demonstrated that the magnesium tartrate can be treated with an appropriate amount of aqueous HCl and added into a subsequent batch of SEL to throw out potassium bitartrate once again which demonstrates the recyclability of the extractant. The overall loss of tartrate over a cycle was ca. 20% but the dissolved tartrate remaining in the K-depleted SEL and KCl solutions can be precipitated out as calcium tartrate from which tartaric acid can be recovered by known methods, curtailing thereby the loss of tartaric acid per kg of KCl to <5 g. It is also demonstrated that through a similar approach, seaweed sap containing ca. 4% KCl can be concentrated to 20-22% KCl, with excellent utilization efficiency of tartaric acid, and this solution can similarly be utilized for SOP preparation. Potassium salts bearing other anions such as sulphate, nitrate, phosphate and carbonate can also be prepared from the isolated potassium bitartrate.

  虽然美国专利号8,182,784教导了使用二硝基苯胺作为萃取剂从锁安石终液中回收氯化钾，并因此简化了使用美国专利号7,041,268所披露的方案从卡因石混合盐中回收硫酸钾（SOP）的过程，但与该萃取剂相关的危险阻碍了该发明的实际利用。许多其他用于钾回收的萃取剂已经在先前的技术中披露，但迄今为止没有发现适合实际开发的萃取剂。本文披露了酒石酸根离子，特别是L-酒石酸，可以非常有效地从锁安石终液中沉淀出酒石酸钾，使用率约为90％。相比之下，直接从海卤水中回收酒石酸钾的效率相对较低。进一步披露了这种沉淀物可以用氢氧化镁和氯化镁处理，回收约90％的酒石酸镁，同时产生一个几乎饱和的氯化钾溶液，可用于与锁安石反应以获得SOP。还表明，可以使用适量的水溶盐酸处理酒石酸镁，并将其加入下一批锁安石终液中，再次沉淀出酒石酸钾，从而证明了萃取剂的可回收性。一个周期内酒石酸的总损失约为20％，但残留在K-贫化的锁安石终液和KCl溶液中的溶解酒石酸可以沉淀出来，从中可以通过已知方法回收酒石酸，从而将每千克KCl的酒石酸损失降至<5克。还表明，通过类似的方法，含约4％ KCl的海藻汁可以浓缩至20-22％ KCl，并具有优异的酒石酸利用效率，这种溶液同样可以用于SOP制备。还可以从分离的酒石酸钾中制备含有其他阴离子（如硫酸根、硝酸根、磷酸根和碳酸根）的钾盐。
