Question

How do you differentiate fractional distillation and mining? ​

Answer 1

Answer:

Fractional Distillation

Fractional distillation is a technique employed for many complex liquid mixtures, i.e., mixtures with components that have closer boiling points. For such systems, simple distillation will be meaningless. Therefore, a modified distillation is required. For fractional distillation to be effective, the components should be miscible.

The apparatus of this method is somewhat different to simple distillation apparatus. There is a fractionating column fixed to the flask which contains the liquid mixture. The fractionating column contains glass beads to provide a larger surface area for vaporization and condensation to happen. For example, let’s take a liquid mixture of two components. On heating the mixture, the vapour formed will consist of both components. At some point, the top of the fractionating column will reach the temperature of the lower boiling point, the component which with the lower boiling point will be distilled. The whole amount of the component with the lower boiling point will be gradually collected into the flask, and the one with higher boiling point remains in the flask.

Fractional distillation is the technique used to purify crude oil into numerous components.

Mining

Mining is the process of digging things out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron. Mining can also include other things like oil and natural gas.

Some mining is done by scraping away the soil (dirt) from the top of the ground. This is called surface mining. Some mining is done by going deep underground into a mine shaft. This is called underground mining. Some mining, such as gold mining, is done in other ways. Gold can be mined by searching in the bed of a river or other stream of water to remove the flakes of gold. This is called panning or placer mining.
