意外收获美国西北大学称这项研究是意外发现的最好例证,而这项成果是由当代基础科学带来的。氰化法浸金所产生的废品会对环境造成巨大危害,而且环保代价高昂,因此这项新发现的工业应用对环境和采矿业来说都是一个喜讯。一种新颖环保的黄金提取法——玉米淀粉法的发现过程纯属偶然,其背后只是简单的试管化学原理,但是却能让采矿运营更加环保。当化学博士后刘志常试图制作合适的三维立方体结构来储存气体和小分子时,他并不知道自己将会发现一种既环保又低成本的黄金回收工艺。在美国伊利诺伊州西北大学,刘志常在研究组的实验 Unexpected gains Northwestern University called the study the best example of accidental discovery, and the result was brought by contemporary basic science. This new discovery of industrial applications is good news for both the environment and the mining industry, as waste from cyanidation leaching poses a tremendous environmental risk and is costly for the environment. A novel and environmentally friendly method of gold extraction - the discovery of the corn starch method is purely accidental. Behind it is a simple test tube chemistry, but it makes mining operations more environmentally friendly. When Ph.D. chemist Liu Zhichang tried to make a suitable three-dimensional cube structure to store gas and small molecules, he did not know he would find an environmentally friendly and low-cost gold recovery process. In the United States, Northwestern University, Illinois, Liu Zhichang research group experiments
