  1. APES Pre-Lab Formative Assessment Copper Extraction and Mine Reclamation and Chapter 14 and 15 • Each of the following is a type of surface mining EXCEPT… • Open-pit mining • Vertical shaft mining • Contour strip mining • Mountain top removal • Area strip mining • 2. Smelting is … • A way to remove the desired metal from the ore using heat and chemicals • Used to separate the ore mineral from the gangue • A way to reprocess old mine tailings • Both a and b are correct • a, b, and c are correct

  2. 3. Today, each of the following is a limiting factor in the mining of lower grade ores EXCEPT… • a. Increased cost of mining • b. Decreased cost of mining • c. Processing larger volumes of ore • d. Availability of freshwater needed in the processing • e. Increased land disruption and environmental impact • When an oceanic plate collides with a continental plate… • a. The oceanic plate usually rides up over the continental plate • b. Oceanic ridges form • c. The continental plate usually rides up over the oceanic plate • d. Subduction zones form • e. Both c and d are correct

  3. 5. Natural gas is a mixture of gases, but primarily (50-90%)... • a. C4H10 (butane) • b. C2H6 (ethane) • c. CH4 (methane) • d. C3H8 (Propane) • e. H2S (hydrogen sulfide) • By far, most of the electricity in the United States is produced by… • a. Burning LPG • b. Burning LNG • c. Nuclear fusion • d. Nuclear fission • e. Burning coal

  4. 7. Each of the following is an advantage of using Nuclear Power EXCEPT… • a. There is a large fuel supply • b. Moderate land disruption • c. Relatively low environmental impact (without accidents) • d. Low net energy yield • e. Low risk of accidents • _____________ is a way to help prevent possible collapse, and dispose of the ore in an environmentally friendly manner. • a. A slag heap • b. Subsidence • c. Backfilling • d. Leaching • e. SX/EW

  5. 9. To reduce the effects of mine waste runoff, surface runoff is often a. Collected and diverted around waste dumps b. Filtered thoroughly before being allowed to re-enter the environment. c. Collected and allowed to evaporate d. Sent to waste-water management systems e. All of the above are correct 10. A less expensive, and more environmentally and economically friendly way to reclaim old mines, rather than using topsoil, is the use of… a. FYM (farmyard manure) b. The leach-solvent extraction-electrowinning process (SX/EW) c. Biosolids d. Municipal sewage sludge e. Both c and d are correct

  6. ***BONUS***10 POINTS*** Discuss two ways that the use of silica sand (which accounts for nearly 61% of the tailings composition of copper ore) helps the environment
