摘要： A method for concentrating an aqueous hydrogen halide starting solution, in particular hydrochloric acid, includes the steps of extractive distillation of the aqueous hydrogen halide starting solution in the presence of an extraction agent in a distillation device, removing hydrogen halide vapor and/or hydrogen halide gas from the upper portion of the distillation device, removing an extraction-agent-containing solution from the lower portion of the distillation device, concentrating the extraction-agent-containing solution which is removed from the lower portion of the distillation device in an evaporation device, and returning the extraction-agent-containing solution which is concentrated in the evaporation device to the distillation device, wherein the extraction-agent-containing solution removed from the lower portion of the distillation device is concentrated in the evaporation device by evaporation at a pressure which is greater than atmospheric pressure.

摘要： The present invention relates to a two-stage leaching process using concentrated hydrochloric acid that upgrades a variety of inferior quality titanium-iron ores into premium titanium concentrate and iron oxide products. The ground ore is leached with two separate quantities of hydrochloric acid after which the dissolved titanium is precipitated from the filtered liquor by hydrolysis. The still soluble iron chlorides are then optionally subjected to oxyhydrolysis to recover iron oxide and HCl. The process was developed for low-grade ores (under 12% TiO2), and can be naturally applied advantageously to higher grade titanium-bearing ores.
摘要翻译：本发明涉及使用浓盐酸将各种劣质钛铁矿石升级为优质钛精矿和氧化铁产品的两段浸出方法。用两份分开的盐酸将研磨的矿石浸出，然后通过水解将溶解的钛从过滤的液体中沉淀出来。然后任选地将可溶性氯化铁进行羟水解以回收氧化铁和HCl。该方法是针对低品位矿石（低于12％的TiO2）开发的，并且可以有利地被天然地应用于较高等级的含钛矿石。

摘要： Provided is a method of purifying hydrochloric acid by removing an organic substance having a boiling point of −25° C. to 120° C. under atmospheric pressure from a first organic substance-containing hydrochloric acid that contains the organic substance and has a hydrogen chloride concentration higher than an azeotropic hydrogen chloride concentration under atmospheric pressure. The method includes the step of subjecting a second organic substance-containing hydrochloric acid to distillation using a distillation tower under atmospheric pressure, to distill out the organic substance from a top of the distillation tower. The second organic substance-containing hydrochloric acid is obtained by mixing the first organic substance-containing hydrochloric acid and water or dilute hydrochloric acid and has the hydrogen chloride concentration lower than the azeotropic hydrogen chloride concentration under atmospheric pressure.
