Treatment method of polyhalite ore dissolution production fluid

The invention discloses a treatment method of a polyhalite ore dissolution production fluid. The method includes a step of mixing the dissolution production fluid with production raw brine to obtain raw material brine which can be used for producing sodium chloride, potassium chloride, magnesium sulfate and/or carnallite. The dissolution production fluid is the brine which is obtained through a dissolution production process of polyhalite ore. The method omits a step of new-building a salt field, wherein the dissolution production fluid is fed into a production salt field with the raw brine together to generate salt under sun in the salt field. The method reduces production cost, reduces technical process and reduces production period, increases sources of production raw materials and increases utilization rate of the dissolution production fluid. 本发明公开了种杂卤石矿溶采液的处理方法，其将溶采液和生产原卤混合得到原料卤水，所述原料卤水用于生产氯化钠、氯化钾、硫酸镁和/或光卤石；所述溶采液为杂卤石矿经过溶采过程以后得到的卤水。本发明省去新建盐田的环节，直接配合原卤进入生产盐田，进行盐田摊晒，降低了生产成本，减少工艺流程，缩短生产周期，且增加了生产原料的来源，提高了溶采液
