查询词典 leaching chloride

In industrial production, the solution can circularly leach silver chloride 11 times when the concentration of sodium sulfite is 2mol/L and the concentration of silver ion is 30g/L after every leaching process.

结合工业生产，确定了亚硫酸钠浓度为2mol/L，控制每次浸出液中银的浓度为30g/L时，亚硫酸钠溶液可以循环浸出氯化银11次。

The experimental results proved the intermediate product of H2S in the leaching of marmatite. The results also showed that oxygen, element sulfur disperser as well as chloride ions could accelerate the electrochemical oxidation of marmatite in sulfuric acid. The electrochemical oxidation of sphalerite was retarded but that of marmatite was promoted with the increase of acidity.

结果表明：在铁闪锌矿浸出过程中有H2S中间产物生成；通氧、元素硫分散剂以及氯离子引入浸出体系均能明显促进铁闪锌矿的电化学氧化；随硫酸浓度升高，铁闪锌矿的电化学氧化不断加强而闪锌矿的电化学氧化受抑。

A preparation method of polysilicate polyferric chloride flocculant by leaching ferric tailings with hydrochloric acid pickling wastewater ,was studied,and the reasonable preparation craft and technological conditions were determined.

研究了以盐酸酸洗废液分解铁尾矿制备聚硅酸聚氯化铁复合絮凝剂的方法，确定了合理的制备工艺和工艺条件。

Brief description is given to the test on the technology for comprehensively recovering gold and silver from tellurium-bearing slag: Tellurium-bearing slag is ground and leached with water to produce crud tellurium dioxide which is then purified through ion precipitation and complexing purification process; leaching reside is leached with chloride to produce copper and bismuth, bismuth oxychloride is recovered through neutralization and hydrolysis and sponge copper is recovered through cementation; gold and silver in the remaining residue can be recycled to the gold and silver smelting system for recovery.

文摘：简述了碲渣综合回收金银等的工艺试验：碲渣经磨矿水浸碲产出粗二氧化碲，用离子沉淀和络合净化法提纯；浸碲渣用氯盐浸出铜铋，中和水解回收氯氧铋，置换回收海绵铜；残留渣中的金银可返回金银冶炼系统回收。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
