Since the elucidation of the leaching process by Mizoroki in the 1970s, the research focused on this problem has increased. As a result, it has been discovered that the leached metals can not only hinder product yield, but they can also remain as contaminants of the final products. Thus, it can be concluded that metal leaching needs to be diminished or avoided more efficiently. This problem is important for the industry and the environment because of the increases in costs and pollution. In 2014, we reported a brief review related to this important feature; now we would like to report on the latest findings on this important phenomenon, including an update on the mechanisms used to explain leaching and the reactions that support those mechanisms and including patents related to leaching in catalysis that have appeared in recent years.

自 1970 年代 Mizoroki 阐明浸出过程以来，针对该问题的研究有所增加。结果，已经发现浸出的金属不仅会阻碍产品产量，而且它们还可以作为最终产品的污染物残留。因此，可以得出结论，需要更有效地减少或避免金属浸出。由于成本和污染的增加，这个问题对工业和环境很重要。2014 年，我们报告了与此重要功能相关的简短评论；现在，我们要报告关于这一重要现象的最新发现，包括用于解释浸出的机制和支持这些机制的反应的更新，以及近年来出现的与催化浸出相关的专利。
