Impact of Industrial Methods of Separating Mixtures and Solutions

Which type of mining is most likely used to extract oil from long veins of oil-impregnated sand close to the surface at the Athabasca Tar Sands in Alberta?
1. Strip mining
2. Mountaintop removal
3. Open pit mining
4. Surface mining
Copper is found uniformly scattered close to the surface in New Mexico. Below is a photograph of a copper mine.

This is an example of which kind of mine?
1. Open pit mine
2. Surface mine
3. Strip mine
4. Mountaintop removal
Mountaintop removal is a mining technique most often employed to extract which material?
1. Coal
2. Diamonds
3. Copper
4. Crude oil
What is the correct definition of "mine tailings"?
1. Fine waste suspended in water
2. Chemicals used to extract ore
3. Unrefined metal ore fragments
4. Surface material over a deposit
Which process is not an example of a refining process?
1. Copper and tin ores are combined to make bronze
2. Pure table sugar is extracted from sugar beets
3. Gasoline is distilled from crude oil
4. The gold in gold ore is dissolved in cyanide solution
Many industrial separation processes rely on evaporation. Why does this process often have a negative effect on the environment?
1. The burning of fuel, which produces carbon dioxide
2. Gas flaring, which releases methane, a significant greenhouse gas
3. Tailing ponds, which often contain extremely toxic chemicals
4. Clearcutting, which disrupts the entire ecosystem
Which method of separating mixtures can have a positive effect on the environment?
1. Water filtration
2. Alcohol distillation
3. Potash mining
4. Oil refining
Which statement about the use of filters is false?
1. Air filters can remove excess carbon dioxide from the fuel burning process.
2. Air filters can remove the particles that make up smog.
3. Water filters can have a positive effect on the environment by removing contaminants.
4. Filters can be made fine enough to remove some bacteria from air or water.
Which statement about the environment and industrial methods of separation is true?
1. Some refineries are attempting to recapture carbon dioxide, which is a greenhouse gas
2. Methane is extremely toxic and must be confined to a tailing pond
3. Evaporation is an environmentally friendly process that uses wind turbines
4. When coal mining is undertaken, the topsoil for kilometers all around the site is contaminated with toxic chemicals
Which of the following substances is a byproduct of the oil refining process?
1. Methane
2. Propane
3. Gasoline
4. Tar sand
