Unit 3: Mining and Mining Impacts
Summary
In this unit, students are introduced to basic mining methods and processes. This unit also addresses some of the impacts of mining (particularly from mining for metals) on the environment and human health, and integrates concepts such as ore grade, economics, and mining-related decisions with resource use and manufacturing. Optional materials are provided so that instructors can modify the unit according to their class schedule and focus.
Learning Goals
Upon completion of this unit, students should be able to:
- Apply different mineral exploration and mining methods in model situations and extrapolate to real-life cases.
- Describe how wastes are created and managed during the different stages of mineral resource production and what can be done to minimize the negative effects of mining and related processes.
- Give examples of how mining activities affect or are influenced by societal factors (i.e., economics, politics, population).
Description and Teaching Materials
Pre-Class Work Reading Students should complete the background reading on the basics of mining and mining impacts before they do the pre-class homework and before class. Similar to many textbook readings, the background intentionally contains more information than will be directly presented in class. The PowerPoint versions can be also be used to help review the material in class. The PowerPoints are large files with many images and may take some time to download. PowerPoint versions: Background Information about Mining Methods and Impacts. (PowerPoint 2007 (.pptx) 44.4MB Oct4 14) Students can download this PowerPoint directly from the Unit 3 Student Materials page. Background Information about Mining Methods and Impacts - Short. (PowerPoint 2007 (.pptx) 44.4MB Oct4 14) This is a simpler version of above, with the same (but larger) images and less text, and may be more useful for classroom use, if desired. Word/pdf versions: Background Information about Mining Methods and Impacts in Word (Microsoft Word 2.7MB Oct4 14) and in PDF: (Acrobat (PDF) 2.4MB Oct4 14) Students can download the PDF version directly from the Unit 3 Student Materials page or complete a similar online reading on the Unit 3 Student Materials Reading page. Unit 3 Mining Glossary of Terms in Word (Microsoft Word 30kB Oct4 14) and in PDF. (Acrobat (PDF) 60kB Oct4 14) Students can download this glossary directly from the Unit 3 Student Materials page. Optional Pre-Class Homework This (optional) assignment asks students to investigate some of the harmful impacts of mines, mining, and mineral processing on the environment and human health. Students research Abandoned Mine Lands (AML) and National Priority List (NPL) sites, many of which are still being cleaned up today. Later in the module, students may draw on this background information when discussing mining in other countries where the regulations are not as stringent as those in the United States. Mining Methods and Impacts AML and Superfund Pre-Class Homework. An alternative version of this pre-class assignment (included in the link above) uses class time to formally discuss the homework using a Gallery Walk. What is a Gallery Walk? In-Class Work Post-Class Work Optional Reading/Assignment for after Unit 3 As a follow up to Unit 3, students are asked to create a concept map detailing the steps necessary to produce a can of soda. The narrative includes inputs from mining, energy, and transportation that are needed to produce components of the can in addition to the soda itself. This assignment allows application of the concepts covered in this unit to the production of a single commonly-used product. The teaching notes include an explanation of the assignment, an example assignment, and a grading rubric.
