跳到0分钟和31秒你好,我的名字是弗朗西斯墙。我是埃克塞特大学Camborne矿业学院教授。我对一些地球最罕见和特殊的岩石进行了研究,该岩石含有现在促进消费电子产品等领域的技术进步和运输的脱碳的金属的金属。在本课程中,我们将介绍这些以前很少的知名,甚至相当模糊的元素变得如此必不可少。我们将称他们为技术金属,我们每天都在不考虑他们真正来自的地方。但它们是我们数字技术,可再生能源生成和低碳运输的推动者。
跳到1分16秒Over the next four weeks, we’re going to be investigating how these technology metals form in the earth and become concentrated into minable deposits, where in the world deposits of these metals are located, how we as geologists find the deposits, and then how engineers and chemists extract the minerals and their metals from the host rocks, and of course, where these elements end up being used. We will consider the environmental impact of obtaining these essential raw materials and explore the possibilities of recycling and the circular value chain.
跳到1分54秒本课程的目的是展示这些原材料在现代世界中越来越重要,并在我们的全球通信网络中以及帮助促进脱碳的技术中概述其关键作用。
跳到2分37秒我们期待着通过渗透现代世界的技术金属的生命周期带你去这段旅程。
