Introduction • Used since pre-historic times • Used for: • Tools/utensils, Weapons, Ornaments/decoration, currency, structures/devices, energy, machinery, electronics, nuclear fission. • Mining- work or business of taking minerals from the Earth • Many different types of mining hard rock, open-pit, underground coal, borehole, copper, gold, deepsea, and mountaintop removal • Small and large scale mining • 60% mining by opencast (deforestation, contamination, alteration, destruction of habitats) • http://media.wiley.com/product_data/excerpt/11/04713485/0471348511.pdf
Process of Mining • Area Selection- • Choose an area able to find mineral, etc • Deposits easily, cheaply, quickly • Helpful looking at maps 2. Target Generation- • Investigate through maps, geophysics, testing surface/subsurface minerals • Methods: geophysical, geochemical, remote sensing • Resource Evaluation- • Quality/quantity of mineral achieved by drilling 4. Reserve Definition- • Converts resource to a reserve • Same as evaluation, more thorough
Continued 5. Profit Planning- • Planning, evaluating economically recoverable portions. • Study, reasons build/not build • Look at: lost/gained profit for future, economical/environmental 6. Mine Construction- • Time varies for different mine i.e. hard rock, open-pit, underground coal, borehole, copper, gold, deepsea, and mountaintop removal • Mining- • Excavation of mineral 8. Ecological Rebuilding- • Reclamation to make land suitable future usage • Return as close to original • After: land becomes degraded

Why Are They Effected? • Deforestation • Water contamination- causing diseases i.e. Malaria • Groundwater • Surface water • Wildlife effects • Habitats • Drinking water • Means of waste removal- i.e. tailing ponds • No reclamation http://www.emr.gov.yk.ca/aam/images/mn_tailings_pond_ds.jpg
Raking in the cash (1) Profitable resources include: • Coal • Petroleum • Gold • Silver • Copper • Aggregate • Limestone • Lead • Magnesium • Natural gas • Zinc • Gravel; sand Popular! http://i.treehugger.com/images/2007/5/24/coal%20chunks.jpg Expensive! http://www.open2.net/blogs/media/blogs/39197167_gold.jpg Useful! http://2.bp.blogspot.com/_grzwYLmE9Ug/SoqyfYgQETI/AAAAAAAAAD0/_Nk8l6Eet_A/s1600-h/petroleum-300x225.jpg

Technologies for the Worse • Opencast mining • In-situ Leaching • Tailings ponds- cause Acid Mine Drainage • Land/River Dredging http://www.planningwithpower.org/images/photos/PicCat/CT/images/RiverDredge.jpg
Acid Mine Drainage About Acid Mine Drainage Formed when pyrite exposed to air and oxidizes, releases sulfuric acid and dissolved iron Iron precipitates forms yellow, orange, or yellow sediments of streams Dissolves heavy metals, copper, lead, mercury Rate and degree mine drainage continues increased by certain bacteria Usually from abandoned coal mines or active ones Contaminates water, disrupts growth, corroding bridges (water infrastructure) http://maps.grida.no/go/graphic/mining_effects_on_rainfall_drainage

Continued… • Testing; water • Reducing water usage • Fuel cells- benefit platinum mining • Trading carbon emissions • Combine tailings + waste rock= safe storage • Using renewable, nontoxic resources http://maps.grida.no/go/graphic/certified-emission-reductions
Effects on Natural Cycles (1) Water: • Acid mine drainage • Kills aquatic life -lowers pH organisms can’t reproduce -Iron Mountain Mine, CA • Dissolves toxic metals - pollutes rivers, streams + groundwater -travels long distances (Summitville Mine, CO) http://cd7.e2bn.net/e2bn/leas/c99/schools/cd7/website/images/bp-watercycle3.gif
Effects on Natural Cycles (2) Soil: • Oil and gas wastes -sterilize soil & prevent veggie growth • Bad water spills -pollute soil and prevent growth -contaminate groundwater http://www.sustainabilityninja.com/wp-content/uploads/2008/11/potting_soil.jpg
Effects on Natural Cycles (3) Carbon cycle: -mining releases methane gas -adds to global warming Rock: -waste rock disposal problems http://blogs.dickinson.edu/copenhagen/2009/09/the-debates-over-humans-did-it/ http://www.blm.gov/pgdata/etc/medialib//blm/ca/images/images/pa_images/aml_images/aml.Par.2955fdf3.Image.500.300.jpg
Effect on Environment (1) • Appalachia region • Lake Coeur d’Alene • 1992, Summitville • 1995, Berkeley Pit, MT • 2000, Phelps Dodge Tyrone, NM • Rainforest mining -gold, copper, diamonds & precious metals -damages ecosystem -causes problems for locals http://www.discoverlife.org/co/images/parks.640.jpg
Effect on Environment (2) • Small-scale miners • Mercury: toxic, highly bio-accumulative • Top predators: highest levels • Risky fish diet • 500-800 tons of gold & 800-1000 tons of mercury • Exposure of metal sulfides • EPA’s prediction http://static.open.salon.com/files/gold1231583227.jpg
Effect on Local Area • Mountaintop removal -requires small number of workers -mining industry lost 10,000 jobs -destroys economy • McDowell County • Machinery pollutes area’s water source http://farm3.static.flickr.com/2260/1935818331_2641bf5e2a.jpg
