What are the examples of magnetic separation?

Answer 1

The separation technique, magnetic separation is used to separate a solid-solid mixture. But WHAT IS A SOLID-SOLID MIXTURE ? It is a mixture made up of solids that are physically combined. Like..

SULFUR &IRON FILLINGS

The iron fillings are magnetic. That is why a magnet is used to separate the mixture. Want to know how?

Here are the steps !

1. Grab a magnet and hold it above the mixture to attract the iron fillings.

2. Gather the extracted iron fillings in another container.

3. Use the magnet again on the newly gathered iron fillings in the container to ensure that we obtain pure iron fillings only.

4. And woila ! We've separated the mixture !

What have we obtained ?

When the magnet was moved through the mixture, it attracted the iron filling but not the sand. This is how magnetic separation is used to separate mixtures.

Magnetic separation is also used in the real world.

REFLECTION !

I think magnetic separation is a very handy technique ! Imagine accidentally mixing iodine and sand. Everyones first reaction would be 'Oh no! How on earth am I to separate these now? Might as well buy a new one.' . But with this technique, we can separate the mixture faster than you can say butterscotch !

Answer 2

if you had a pan of gold and dirt you would swish the pan around and wait for the gold to sink to the bottom because it is heavier. AND THAT IS GRAVITY SEPERATION. Also gravity is like when you throw a ball in the air and it alway's comes back down. These are Gisselle's a.k.a ( Dont leave me Alone ) example's of gravity.

Answer 3

If a mixture that contains liquids or particles that have different densities the particles that are heavier will tend to sink to the bottom.

If you vigorously mix oil and water, for instance, the mixture will separate if left undisturbed and two phases will form with the denser phase on the bottom.

Not all materials can be physically separated and those that can do not always separate with just the influence of gravity.

Answer 4

Gravity separation is when gravity is used to separate an non pure substance.

Answer 5

* going down on a playground slide

* an apple falling down from a tree by itself

* the earth circling the sun or the moon circling the earth

Answer 6

An example is waste disposal. Before the waste gets dumped in landfills, it is sorted, and magnetic items are separated out of the other waste materials by using a powerful magnet.

Answer 7

To separates metal like iron or affinity to wards magnet
