o people left: Xiao Jingyu and Xiao Zheng. 。Today, Xiao Zheng saw at the venue how Xiao Jingyu argued for him with reason and conviction. 。Before, Xiao Jingyu rejected Xiao Zheng's proposal to marry h...Li Jiao Chao Yunqi nodded, then said: “That's because considering that most of the people present today wouldn't be able to recognize the two minerals 'keng' and 'qiang', nor know how the two minerals can be fused together, so I invited two teams of scientists today” 。One group is composed of scientists from the Ministry of Metallurgy, who are responsible for extracting "clang" and "bang" metals from minerals and fusing them into a new material called "clangorous"! There is another group of scientists from the aerospace agency's materials department, who will evaluate the potential applications of this "clangorous" new material in the aerospace industry. 。Okay, let's begin!
As Professor Li Jiao gestured outward, two small white devices were pushed in by personnel in white coats. Subsequently, the two ore samples originally on Professor Yunqi’s table were removed and placed into the first white instrument for ore extraction. 。Under the skilled operation of two technicians, the instrument began to rotate, emitting red and golden light inside. 。According to scientists, there are many methods for mineral extraction, such as flotation, magnetic separation, gravity separation, and acid leaching. Sometimes, multiple methods are used in combination. 。and the instruments on site, specifically designed to extract precious minerals, treated all other minerals mixed in the ore as waste, retaining only the most valuable "keng" and "qiang" minerals. Thus, it could also be considered a simple process!
The entire process lasted for over half an hour, but because the whole process was very novel to everyone, no one felt it was too long. 。After theting. 。Everyone began to walk along the dirt path between the tea mountains, down the slope. 。As soon as they arrived by the small bamboo grove, they saw a long line of villagers blocking their way. 。...
