Minerals and Society Not only are mineral resources important to the economy but the mining and processing of minerals also have important social and economic impacts. The questions below address three examples. Please use complete sentences. 1. Rare Earth Elements and Green Technology a. Go this web site to find out about rare earth elements (REEs) and their uses: http://www.bbc.com/news/world-17357863 1. What are the rare earth elements? 2. Write a brief summary of how REEs are used. b. Read the article “A Scarcity of Rare Metals Is Hindering Green Technologies” (http://e360.yale.edu/feature/a_scarcity_of_rare_metals_is_hindering_green_technologies/2711/ ) to answer the questions below. This article was published in 2013. Use complete sentences. 1. Explain the author’s statement that rare earth elements are “scarce thanks to both geology and politics.” 2. Although there is a high demand for the rare earth elements, recycling of these metals is not common. Why? (give at least two reasons). 2 ` C. Now read the High Country News article that is available as a PDF in the assignment. This is a more recent article published in 2015. It’s long, and I am only asking you to read the highlighted sections for this assignment. Once you’ve read that, answer the following questions. Use complete sentences. 1. Are rare earth elements actually rare, either politically or geologically, at this point in time? Try to compare what you read in the Yale article with the High Country News article. Write a few sentences. 2. As of August 2015, Molycorp has closed down operations at the Mountain Pass mine. Based on what you have read in both articles, especially the HCN article, what do you think this means for US efforts to mine REEs? 3. Do you think the government should subsidize this type of facility to ensure a domestic supply, or do you think the global network of mines outside of China, and recycling technology, are sufficient for our needs? 2. Conflict Minerals and Your Cell Phone Watch this video from PBS : http://www.pbs.org/newshour/bb/entertainment-july-dec13-bleasdale_10-05/ a. What “conflict minerals” are being mined in the Congo? b. What are the social impacts of this mining? 3 ` c. The Congo is one of the most mineral-rich countries on Earth, but it is also one of the poorest nations in the world. Why? 4
